Should everyone play single-length irons?

Published

on

Recently, there’s been a lot of interest in a set of irons where each club is the same length. When a talented young player on the PGA Tour uses clubs this distinctive and different, it is going to generate some headlines. It has also sparked some interesting questions about matching clubs in a set in the golf equipment world. I have some experience in alternative ways to match a set of clubs. In fact, my first project at PING was to build an inertia-matched set of irons. I hope this article provides some useful information about matching an iron set.

The idea of a set of single-length irons sounds appealing: If every club has the same swing feel and can be swung on the same plane, it would seem easier to groove one swing for the majority of shots. However, current sets aren’t just different lengths — they’re also different weights, have different lie angles and generally optimized for length progression. They’re also optimized to achieve good distance gaps between clubs. So to begin this discussion, we need to pinpoint what makes up the feel of clubs.

There are many ways to describe the feeling of weight, especially in an object intended to be swung at high speed. For those wishing to explore this topic in detail, I recommend a book called “The Physics of Golf” by Theodore Jorgensen. It was one of the books I really valued during my first couple of years at PING. Jorgensen describes three ways to measure the feel of weight of a club. To understand, it helps to imagine the golf club as being made of a collection of little 1-gram weights, or masses, all stuck together, as shown in Figure 1. In the diagram, the black circles represent the grip, the grey circles the shaft and the blue circles the head (if it’s not abundantly clear, I’m not employed for my artistic abilities). Hopefully you get the general idea.

Figure_1_swing_weight

Figure 1: Diagram showing how a club can be viewed as a collection of 1-gram masses where the feel properties of the club are described by each mass and its distance from the pivot point.

Jorgensen’s 3 measures of feel are:

  1. Mass. You can feel this by picking up the club at the shaft and holding it. It is simply the sum of all the little 1-gram masses in the figure. Adding more mass, whether to the grip, shaft or head, will add to total club mass and make it feel heavier overall.
  2. The first moment (swing weight). You can feel this by holding the club at the grip and then pointing the head straight out in front of you. You can feel the “weight” of the club pushing down on your bottom hand, trying to rotate. This value is calculated by taking each little 1-gram mass and multiplying by the distance from the pivot point. It’s measured in mass-distance or inch-ounces on a standard swing weight scale. So if you add 1 gram to the head, you’ll feel the effect much more than if you added 1 gram to the shaft. Adding 1 gram to the butt of the grip can even make the club feel lighter by this measure. On an actual swing weight scale, the pivot point is 14 inches from the butt end of the club, for reasons no one is exactly sure about, other than it has worked for the last 20 to 30 years. If you were trying to match a set to a true “first moment,” you’d use a pivot point more like 5 inches from the end of the grip (between the hands).
  3. The second moment (club MOI). You can feel this better by waggling the club around. It is the moment of inertia (MOI) of the club around the golfer’s hands, and is often called angular mass in other engineering fields. This value is calculated by taking each little 1-gram mass and multiplying by the distance from the pivot point squared. It is really a measure of how spread out the mass is, and is often described as a resistance to twisting. This value is much more sensitive to even a small amount of mass added to the farthest location from the pivot point. You are used to hearing about the MOI of the club head around the center of the face — a measure of the “forgiveness” of the head. In this case, we’re talking about MOI of the whole club around the hands. Same physics principle, but different axis of rotation.

So why do we care about all this? Because there are two somewhat competing priorities: distance and accuracy. In theory, we would match clubs so that it’s easier for golfers to swing all of them accurately and consistently, but golfers also want more distance. Jorgensen starts his chapter on club matching this way: “I thought perfectly matched clubs should all swing the same and therefore… increase the precision of his game. I found, however, that most golfers were interested in clubs that would give them greater distance on the course…”

Our design intent is to find the optimal balance of distance and accuracy through a set of 14 clubs for any given golfer. One of the main levers to alter distance in particular is the length of the club. If a driver is 45 inches and the shortest wedge is 35 inches, that 10-inch differential plays a big role in achieving good distance gaps while maintaining stopping power with each club. For example, a 4-iron at 7-iron length makes it difficult to generate the same height or distance you’d produce with a standard 4-iron. Moreover, as we change length, it’s difficult to match all three feel measurements to get the clubs to truly feel the same. Table 1 shows some typical values of mass, swing weight and MOI for a few clubs in the G family. You can see that swing weight stays somewhat constant, but the mass increases from driver to PW, while the MOI decreases. This is a function of the design trade-offs made for each club in the set.

Ping_G_family_weight_MOI

Table 1: Typical values of club mass, swing weight and MOI (around a pivot point 5 inches from the grip end) for selected G clubs in a set.

So, all that said, is there a benefit to having at least the majority of clubs in a set at the same length? It’s a tough question to answer, because the results can only really be built up over time using a single-length set on the course. The trade-off seems to be better consistency when switching from iron to iron in this set, but the driver and fairway woods will feel very different from the irons, and it might be a struggle to achieve good distance gaps in the set.

The fact that at least one player has had good results on the PGA Tour shows that a single-length set can be effective, but that does not mean that it would work for everyone. The most famous current exponent of the single-length iron set also plays extremely upright lie angles, is a dedicated disciple of the Golfing Machine instruction system, and has been working diligently at this for years. His single-length iron set is matched for mass, swing weight and MOI, and allows him to use the same swing plane for all of his irons. However, the metal woods are still longer, lighter and have higher MOI. It’s probably unrealistic to expect that just chopping down your shaft lengths will by itself make a big difference. You can see from Table 1 that to make a standard 5-iron at 7-iron length, we also need to add 20 grams to the mass of the club to make it match.

I suggest the best candidates for a single-length set of irons are higher swing-speed players (who don’t have trouble generating distance) who want to take the time to experiment with their game and determine objectively whether the pros outweigh the cons. I don’t recommend that anyone buy such a set on a whim. It takes a lot of effort to adapt a set designed for progressive lengths into a functional single-length set. If you are interested, at least go and talk to a master club-builder for advice.

In the future I could see this approach working for people just taking up the game. In that case, I foresee a set featuring just a few clubs, all the same length. Out of curiosity, I’m tinkering with some single-length irons and hybrids myself right now. As my scientific training taught me, I’ll remain skeptical until I can verify some measurable improvement in my results.

    I am a senior golfer and play one length irons (5I thru pw) which make distance and repeating distance easier. They were assembled by West Georgia Golf, using golf iron heads which vary in weight, but are all assembled to a 7 iron length. I had heavy grips installed. Each club has lead weights installed at the grip end of the shaft, to provide good feel. I like the added distance and long flights. The shafts are FST 90 gm steel.
    I am assembling a practice pitching wedge with small head cast from soft 304 stainless which will also be the same length and same counterweight. This will help my accuracy.
    This is a good solution for seniors with less distance.

    I built and play a set of 2 length irons with matched MOI. Love them and will not change back to standard. Some info below.

    First:, excellent explanation and illustration of CLUB MOI. I am a PhD Mechanical Engineer so I recognize that MOI matching provides a true match. Considering the three matching methods, I will add the comment that total weight does little ir anything. The “swingweight matching” has simply been a sales tool because it is easy to measure and illustrate. However, keep in mind the most important feature of a golf club is ball striking – that is a process of motion which is described by the subject Dynamics – the science of predicting motion of an object knowing the applied force and the object weight and weight distribution. This is not simply a “theory”, this is what landed people on the moon, guides space probes for billions of miles, as well as describes object motion on earth. We need not examine the equations: but note that the “swingweight” concept (mass times distance) does NOT appear in the equations of motion and therefore, has nothing to do with club motion or club matching. The club MOI is the key object parameter for circular motion – like the golf swing. If you want matched clubs, use club MOI – see Wishon Golf.

    Second, a few comments about building a set of 2 length irons from standard available club heads, shafts and grips. Dr. Wood is correct: one must adjust the weight of commercial heads to build a 1 or 2 length set of clubs. I found that this is easily accomplished making a 2 length set instead of single length set because it decreases added weight. My set features short irons 9,8,7,6 all 36 inches long, all shafts trimmed like an 8 iron. I matched head weight by adding tungsten powder + shafting epoxy to the heads that need weight. I used Hireko Golf Prophet CB iron heads because of good feel and the recess on the back of the iron is a convenient place to add weight. You will add 7 grams to the 7 iron head and 14 grams to the 6 iron head. For the 9 iron, I left the weight alone and simply made the club a1/4 inch shorter ( calculation using calculus; verified by measuring club MOI). For the long irons 5 and lower numbers you do the same weighting procedure to increase the head weight to equal a 5 iron head and you make the clubs 37 inches long – again a calculus prediction that was verified by measuring the finished product. Long iron shafts are the same brand as short iron and are all cut like a 5 iron.
    With 2 length irons, you have one swing but play the long irons about 1 ball ahead in your stance. Very simple, very repeatable, all distance gaps between clubs are 10 to 15 yards just like multiple length irons. This too is predicted by Dynamics, but is a subject for another discussion.
    One or two length irons will be very helpful for beginners and intermediate skill players. If your are a 5 handicap, you already mastered the complexities of multiple lengths and standard construction so you may try and experiment, but you may not change.

      Bruce, I’m having a hard time understanding your logic behind the 2-length set that you made. You said that you took your short irons (6-9) and weighted all the heads to equal that of the 9-iron head, but then used an 8-iron shaft (which would mean you soft-stepped them) and made them to 36″ which is a standard 9-iron length, but made the 9 iron -1/4″ shorter (even though it weighed the same as the other heads?). And then with your long irons you weighted all the heads to that of the 5-iron, then used a 5-iron shaft (so not soft-stepped like the short irons) and made them to 37″ which is 1″ shorter than a standard 5-iron. So the final set will result in shafts in the 3-5 irons which play true to flex and are 1″ shorter than standard length, while the 6-9 iron will play to a slightly softer flex and be standard length? Why the two different lengths and flexes? Isn’t the whole point of doing something like that to make everything feel as close to the same as possible?

    If the prodigy of Bryson Dechambeau will set out positively, my guess is it will only be a matter of time that some big oems will offer a SL-set.
    Not as radical as his irons and probably not offered as 1 set of SL-irons but more likely in 3 (or even 2) departments to cover long, mid and short distances.

    so much talk about single length clubs just wait until De Chambeau wins on tour and it will really explode.Many people have replaved the 3 and 4 irons with hybrids which go higher anyway negating some of the problem of low trajectory with those clubs also using a shaft with a lower kick pt in the lower lofted clubs while keeping all other things the same will further mitigate this factor.The wedges should be left out of the discussion.An easy way to try the single length method is get five 7 iron heads preferably forged because you are going to be doing some bending but only for loft by using 7 iron heads the weights and lies will already be constant.Assuming the heads are all 32 degrees of loft bend one head 8 degrees strong to make the 5 iron one 4 degrees strong to make the 6, one 4 degrees weak to be the 8 and one 8 degrees weak for the 9 install 5 7 iron length shafts and you have your set.The main drawback is by changing the lofts by bending the bounce of each club is changed but this a way to see if single length irons are a viable option.In a standard set of clubs the 5 iron is only 1 inch longer than the 7 and the 9 iron 1 inch shorter than the 7 so the change is not as drastic as many think.

    I am 47 years old. I am 22 months into my golf career. Yes, I STARTED playing golf at age 45 in July 2014.

    Starting out, I took 3 months of lessons using my first set of clubs (Adams a12os). My ‘game’ was a mixed bag as you can imagine being such a novice. The different set ups, ball positions, swing planes, lengths, and weight just confused the hell outta me and I had no consistency. So, I basically played with a 7 iron, a 3 wood, and a putter. Let’s just say I was double or triple bogy golfer. Sure, I would get a par now & then …. largely based on luck.

    Because the different set ups, ball positions, lengths, etc confused me so much, I looked into single length play (specifically, David Lake’s One Iron Golf). I read every single word on his website and the downloadable PDF. It all made sense to me & was ‘logical’. So, when my Adams clubs were stolen, I quickly purchased a set of One Irons from David Lake.

    The One Iron set I ordered had 5 iron through PW, a 5 wood, and a 7 wood. I have since added the 3 wood. I do not hit a driver off the tee …. I use the 3 wood. The irons are all the same length, head weight, lie angle, bounce, shaft flex, MOI, grips …. the ONLY variable is the loft (which is in progressive 4 degree increments). The woods are all the same length, head weight, lie angle, bounce, shaft flex, MOI, grips …. the ONLY variable is the loft (which is in progressive 4 degree increments). The head volume on the woods do vary, but the head weight is identical.

    Thus, I have 2 setups/swings to groove …. 1) my iron swing, and 2) my wood swing. It has been a God send for me. I hit clean shots with FAR FAR more consistent & solid ball striking. My golf buddies who have 30 or 35 years of experience compared to my 2 years, are pretty damn impressed at where my game is (relative to theirs) in such a short time. Now, believe me, most on this forum would whip my ass out on the course …. I am not claiming to be a “good golfer”. What I can say is that my scores have dropped significantly (shot a 49, 50, 51, 48 my last 4 times out). Consistent bogey golf (45/90) is my goal …. I think I’ll get there by this time next year.

    As other posters have stated, I think Single Length/Lie/Weight/Flex/MOI concept makes a lot of sense for NEW golfers, not golfers with years of experience who have crafted their game over time with standard clubs.

    One last note: Do not think of “Single Length Irons” as a conventional set all cut to the same length. Obviously, that would not work. It isn’t “Single Length” only …. in reality it is “Single Length/Lie/Weight/Flex/MOI” clubs.

      That’s great! But allow me to let you in on a secret.
      In golf, it doesn’t matter what the equipment is – as long as it helps you hit it fairly well in the direction you want, at the distances you can control.
      But the crux of the game is…….. you have to know how to putt. You have to know how to get it in the hole on the green. Your reported score means nothing, unless you tell us how many putts you had while getting those scores. Then you really know how your score broke down. Of course, it helps to be able to get the ball closer to the hole with your shots from the fairway….. as well as getting into play off the tee.
      And your SW and LW (if you have it), are a different length than the irons, right?

    • cgasucks

      May 25, 2016 at 12:56 pm

      You shouldn’t have 2 different swings (one for irons and one for woods). The swing is the same for all clubs. Ball position and stance differs as the club gets longer.

    • Regis

      May 25, 2016 at 5:27 pm

      There are more than a few legends of the game (Nicklaus to some extent) that believe that there is one swing for normal shots and that all shots should be played from the same position vis a vis your left heel with the only variable being the width of your stance. Yet others believe moving the ball position progressively back as each club gets shorter. I personally believe that there are different swings for driver and fairways than for irons and you can hear all sorts of absolutes as far as how to play a fairway wood off the deck. When you get to the top ball strikers, they may focus on which groove on the clubface they want to be the point of contact. I wouldn’t over think it.

    The end of the article says it all. If you are interested in trying single length irons, see a professional club fitter. Getting the right length and weight shaft is critical, as is getting the proper distance gapping. That is why a major OEM will never succeed in making a set for retail. There are too many variables for the correct fit. Tom Wishon has dealt with the height issue of the 5 iron by also making a 5 hybrid for those that have a problem hitting the same length 5 iron high enough. Single length is not for everyone, just like there is no length 6 iron that is for everyone, or one shaft flex or one shaft weight. Whether you want to try single length irons or traditional variable length irons, seeing a professional clubfitter is the only way to play to the best of your ability.

      If a customer wanted to custom order single length irons through PING they could. The CTP weights or the addition of tungsten through the WRX dept would allow for the added weight necessary for the single length.

      • Jim

        Jul 17, 2016 at 2:32 am

        Yeah, but you’d have to make all the heads the same weight as the PW because you can’t make that head any lighter than it is. And I don’t think a SL set where they’re all made to PW length would work very well.

  11. Scott

    May 25, 2016 at 9:54 am

    What I do not agree with in the article is that high swing speeds are required to provided enough distance separation on single length clubs. That is true on traditional length clubs also. My wife hits her 5, 6 and 7 irons all about the same length, the same with the 8 and 9, and the majority of her wedges.

    I have noticed that the majority of golfers (good and bad players) have much better posture on their long irons vs. their wedges. They are way too hunched over on their short clubs, which results in every poor shot imaginable. Since most bad golfers don’t hit enough greens with any club, giving them one posture to work with, I believe, would help with their consistency dramatically.

    Most of your readers are too young to remember the Tommy Armour EQL model of irons way back when. Every club was the length of a six iron. That set bombed big time and was off the market quickly.

    Now some young guy comes along (DeChambeau) with a home made set like that and all of a sudden the industry is talking about it again. Then there were titanium irons. They bombed. Remember Featherlite golf clubs, Mac Golf, etc. They were all the next big thing.

    Misleading title and weak article… The Physics of Golf actually supports the concept of single length irons, and Tom Wishon (Sterling Irons) and David Lake (1-Iron Golf) +others already sell irons designed and manufactured as single length; it would be absurd and exceptionally difficult for an individual to modify an existing set (as Edel did for Bryson). All of the SL clubs have identical specifications except for loft, which means they all have the same balance, total weight, swingweight, MOI, feel, etc. Since all of the clubs have identical shafts and lie angles, the setup, alignment, and swing plane can be the same for all of the irons (which by design should be the same as your favorite club). Since loft is the primary determinant of distance, those with slower swing speeds can still achieve consistent distance gaps by using 5 degree changes in loft (vs the 3/4 that traditional manufacturers use). BTW, Tom Wishon uses higher COR faces in the lower lofts to help with distance gap concerns.

    I will build everyone in favor of equal length sets a set of their choosing, so long as we go play for money when the clubs are complete. SL clubs are dumb for everyone outside of a small percentage of a small percentage of golfers. They will kill what little chance you have at enjoying the game and make everyone around you miserable due to your constant ramblings about swing plane. Physics doesn’t change due to what you believe would happen if Big OEM would just produce what you obviously know to be best. Thank you Dr. Wood for at least trying to slow the rampant effects of the Internet a bit. It was a solid effort, perhaps a bit more about the effect changing length has on max height, and how due to maths, the result is a change in distance. Might of helped. I doubt it, but who knows.

      May 25, 2016 at 7:27 am

      You completely forget that a vast majority of golfers and the vast majority of consumers are casual golfers. This is what is wrong with Golf. Everyone only thinks about the few percentage that actually play in sanctioned events, tournaments, and so forth and completely ignore the majority of golfers that pay the bills.

      A vast majority of golfers who just show up Saturday with a set of clubs that has never been, and will never will be fitted are the folks who would truly enjoy the game from a single length set of clubs. The problem is NO ONE wants to tap into that potential because they are so ingrained on getting fitted. Single Length irons are the best for learning the game, because it is ONE swing. ONE swing between all your irons. The one problem a vast majority of golfers have issue with is the swing, so give them one swing, and let them enjoy the game.

      • Ryan Christensen

        May 25, 2016 at 1:56 pm

        There is only one swing! You swing every club, driver to putter the same. This is the simple fact that weekend golfers cannot seem to grasp. SL clubs would be a disaster for a causal golfer who already struggles to find a consitant ball flight. The picture at the top of the article is a perfect example, that’s an nFlight readout that shows trajectories throughout the set. Length progression is what allows all of the max heights to be in the same neighborhood. A SL set would be really high in the short irons and excessivly low in the long. For a casual golfer, this means that distance control is out the window and most of their clubs go the same yardage. Not to mention, they would need a more in depth fitting for SL irons! The point of them is to find the iron you hit best and build the rest of the set around that. This would also require actual club builders who can control a lot of variables and manufacturing that can control head weights, shaft weights and grip weights to the gram. Which they cannot. Some come close but then the price would be so high, no one could afford them. What your forgetting is that there are people who have dedicated their lives to this game and have already thought of these things.

        • Smith

          May 25, 2016 at 4:45 pm

          incorrect. Every separate lie angle, and every separate ball position represents a different swing plane. Single length clubs means one swing plane across all irons. There is absolutely no evidence to support your claim.

          Tell me, is it easier to swing the 7 iron over and over or swing each individual club in a different setup with a different ball position for each club?

          And yet the correct build for them is to find the one that they do the best with and base everything else on that one.

    Because if all you people switch to single length irons, we cannot fill your bag with all those useless 3 degree loft difference clubs and line our pockets. Seriously, most high handicappers and occasional golfers could do very well with single length irons and single length woods. Say a 5 degree loft gap between clubs. Driver,4w,7w and 5,7,9,SW, and putter. And instead of making clubs lighter and longer, make them shorter, heavier, and more flexible. I am not a golf club maker although I have built several component sets for myself and others. I am also a retired manufacturing engineer so I know about weight and motion, etc… Using my keen eye for detail, I also have observed what other golfers have done in my 35 years of playing. Telling some to use the 3 wood that they hit 220 off the tee instead of the driver they hit 190 is sometimes a futile task.

      Part I agree with, and part I disagree with. One of the problems with golf in the older days was the heavier club issue. Clubs had to get lighter and as a result they got easier to swing, but you can go too light. So far a lot of research backs shaft weights around 100-110g as being ideal for 90%+ of golfers out there. So if I was to build a set to sell I would keep the weight in that range for shafts.

      I do agree with the lofts, and that is probably one reason OEMs use to say why single length clubs won’t work. With single length clubs you have to have at least 4* gaps which is what the gaps used to be 30 years ago. The loft jacking causes the gaps to shrink in the long irons. OEMs bank on the distance through loft jacking so to reverse course and go to 4* gaps at start at a 24 or 25* 4 iron which is the lowest loft that is comfortable to hit, would cause several clubs in the bag to not hit as far.

      However; It can still be done. You market a single length iron set around easy of play, not distance, and people will bite. OEMs seem to forget the motto “you build it, they will come”. There are currently 3 quality brands that build Single Length irons. One, does it like a mass marketing should be, a standard length of a 7 iron with standard lie of a 7 iron, and upon request you can have that adjusted. The other two push more for a quality fitting to get a set, which is a turnoff to the masses.

      The ideal Single length setup would be a standard 7 iron length 37″ with the standard lie of a 7 iron 61.5*, use shafts around 110g and keep the swing weight around D2. Build the set with 4* loft gaps starting with 24* with the 4 iron. You’ll get lofts of 24, 28, 32, 36, 40, and 44. Now you cut the need for a GW by allowing a PW to be 48* and use a 4 or 5 degree gap for the remaining wedges. No yardage gaps, length and lie fit the standard profile of clubs today, which means the 90% of golfers who never get fitted can still play them without any issues.

        Along with the heavier weight, I would also advocate something I call the “gravity swing”. Basically you take the club back at a slow to moderate pace with a slight pause at the top, then you let the weight of the club take over the downswing with the hands and arms just along for the ride. In short, you let the weight of the club do all the work.

        I adopted this method umpteen years ago and have never looked back. Of course, it is sort of my natural motion so it may not work for all. Whenever I try to swing with lighter weight shafts, I simply pull every thing left. For reference, I use a 70 gram driver shaft, 78 in the 3 wood, 85 gram in the hybrid, and 128 grams in all the irons. All are also tipped halfway between R and S flex to match my speed and spin requirements. I also swing these clubs a few miles faster than their lighter weight counterparts.

      Bravo, timck! You’re exactly right. I had to take a limited set on vacation several years ago–something about the car being full of Her stuff. Played better than usual. With the concurrence of my doctor (who wrote me orders to play golf!), I’ve been playing with D,H,5,7,9,PW, SW, P ever since, carrying them in a Wellzher Sunday bag (his orders included walking and carrying). An 8-degree gap is as close as 95% of all golfers really need and the hybrid takes care of controlled tee balls, long shots from the rough, and many chips. I looked at single length, but they’d be really tough to build–I build component clubs, too.

      Fitting clubs starts with matching a shaft to your swing and then determining lie and length (for each club, not just the 6I). Grip size is also important; more people need a bigger grip than they realize.

    Bryson’s been playing this way for a long time – and there’s certainly no reason a newcomer to the game might not want to try this approach. With a properly designed set – weights, flex, lofts, etc – there’s no reason it couldn’t work reasonably well. For those who already play, yes, it would be an adjustment of significance, and probably wouldn’t work for the majority who try it. (Unless they’re completely determined to stick with it).

    The title is silly; has anyone, anywhere, ever suggested “everyone” should play single length? I’ve not seen that. I’ve seen a few suggest that no one should – which is equally ridiculous. It’s another option in an extremely vast array of equipment and approach options.

    Phil Mickelson has 42 tour wins; should every right-handed player play lefty?

    I don’t understand why many think that single length clubs will be hard to adjust to. You are swinging the same length, same MOI, same weight iron for every shot……..what is to adjust to?

    Just about everyone can consistently hit their 7 or 8 iron. Now, with SL it is the same every time. No, reason you can’t hit draws or fades, or get consistent distances.

    All the absolutes and disagreements over this is very confusing to me. It’s an interesting philosophy that if you are interested in, you should try it. It’s great that they are putting out detailed information on the pros and cons, as it isn’t an easy switch to make and should be done thoughtfully. But if you think its absurd and is a bunch of hype, don’t try it. and leave it at that. How are you going to hate on someone trying to find something that works for them? Isn’t that what all of us are doing? I feel like a lot of people take a very defensive position on this that is more a fear of the different than anything else.

    Golf is about what works for YOU and what feels right for YOU, not trying to be squeezed into someone else’s box. If your biggest argument (and again, why are we arguing??) is Bryson, let the kid be pro for more than 3 hours before making your final conclusion on his ceiling.

      The point about Bryson is that if this method is truly revolutionary, we should be seeing revolutionary results NOW. A win here or there (and even that has yet to happen) isn’t enough to suggest we’ve all been going about it the wrong way all this time. AND believe me when I tell you no one is more interested in unconventional approaches than I am, because so very few of us ever have any real success with the conventional.

      Bryson won the NCAA Champ and US Amateur in the same year. The only two other people in golf history to do that were two losers named Jack and Tiger. I bet those two losers are garbage men now.

      What do you mean he has no wins?

      So Bryson has some missed cuts. The cuts that he has made are a T4 and T7. That’s still better than what most rookies on the PGA Tour do.

    I guess it is easier for OEMs to market against the single length than to actually make one. This is just a bunch of mumbo jumbo to market against the norm. They probably have the next two years worth of irons already designed just dont want to jump on this train. Wait 2 years and you will see about every OEM with a single length set. Also it is easier for them to sell off the rack than custom build for every golfer. Not Golfsmith custom a true custom fit. So I see why they are all dogging on the single length set. Dont want non off the rack items for easy sales. Nothing worng with that just harder for them to be true custom

        I have a lot of experience with using non standard length irons and woods. The key to single length irons is to adapt the lofts to the speed of the player. Some would use the old 3 and 4 degree gaps, some 5 and 6 degree lofts, perhaps others more large gaps. If Ping can crack the code they would rule the market place.

    First and foremost, you CANNOT use a single length set from a Driver to a wedge, LOL, so you are way off on that. This article should have stuck with irons only and nothing else. There are no issues gap wise with a proper single length set of irons. Tons of research to back this up, so you are way off point.

    Second, you only recommend this for high swing players? Really? Who is paying you to write this. That is total garbage. The whole Single Length debate is always been centered around how much more beneficial it is to someone first starting out, because they only have to learn ONE swing with their irons. So suggesting that the average guy stays away is completely against all research on Single Length irons.

    Clearly this article is heavily biased and manipulated to make single length look horrible. 1. because you are trying in driver, wood, hybrid, and wedges into the single length. 2. you don’t back up or support any of your 3 measurements for a single length set. All you do is show the differences in a normal set. In a single length iron set all the SW are the same, the MOI is the same, the Lie is the same. Everything is exactly the same, so telling people you have to match MOIs and SWs is all BS. True single length irons are literally the same from top to bottom and the only difference is loft. There is no balancing act. One you determine the best of your 3 parts, your set, that is the setup for every iron. No variation what so ever.

    I think you tried converting a traditional set into a single length set and it didn’t work out. That is the only way the numbers don’t match up, and is the WRONG way to build a single length iron set.

    • Whackenputter

      May 25, 2016 at 10:51 am

      John Boy,
      I wish you would have written the article instead of the author. You obviously know the more about the subject and how to present an unbiased evaluation than him.

      The MOST IMPORTANT point, in my opinion, in the whole SL discussion, and playing golf in general, is MUSCLE MEMORY. With single length IRONS (which is the only question to ask) one trains ones muscles for one single movement, NOT NINE (or seven, or whatever).

      The conventional golf swing is so complicated that major tour professionals cannot even maintain it from week to week. This is demonstrated by the players bouncing all over the ranking from one week to the next.

      I am convinced that by learning ONE SWING for all (or most of) the irons, a golfer will be more consistent.

      Regarding hitting for distance, that is not as important as accuracy, IMO. It seems to me that for everyone not in the top 30 golfers in the world, putting the ball right where you want it, rather than somewhere 300 yards away, will be more helpful in lowering their scores.

      It also seems to me that I should not rely solely on face angle to determine my distance. I have noticed that I can hit harder or softer to control the distance. If I am only using one memorized swing, varying the speed of the swing is much simpler than remembering how my muscles felt the last ten times I used an eight iron as opposed to a seven or nine iron.

      I am convinced that matched single length irons allow the body to learn one swing well and apply that every time one uses irons, instead of trying to guess what you think you might remember about how you last swung a particular iron.

      • Brian

        May 25, 2016 at 2:08 pm

        I’m not pro/anti SL irons. I’m sure they would be great for some and awful for others. The part I don’t get, however, is how Pro- SL iron lovers claim that you only have to learn “one iron swing” instead of multiple iron swings? Unless, there is some golf course that I am unaware of that is completely flat, then the angle is going to change from swing to swing regardless of the SL club due to the lie. Ball above your feet or below your feet instantly changes the theory of “only one set up”.

        • John Boy

          May 26, 2016 at 9:53 am

          The “one swing” is a simple concept. Regardless of the lie the ball rests on, you still position the ball in the same place in your stance.

          For example, lets look at how you would address the ball from a 4-9 traditional set. The 4 iron you stand more upright because of the lie and length. You place the ball more forward in your stance. As you go down to the 5, 6, 7, 8, and 9 you start to do 2 things. 1st, you stand closer to the ball and more flat. 2nd, you adjust the ball position further back in your stance. This means from a flat lie perspective you have 6 different combinations to swing the club correctly on plane to make an effective strike. Now when you factor that into a downhill lie it doubles to 12 different combinations because you also have to adjust for the downhill lie for each club. And for each additional possible setup you add another 6 different setup potions for the ball. That means using the traditional flat, uphill, downhill, higher left foot, and higher right foot, you have a total of 30 different swing combinations you have to learn and use between all your irons.

          Now with Single length irons it is different. There is only 1 combination for all the irons. Example, where you place the ball with the 4 iron and how you address the ball is the same for the 5, 6, 7, 8, and 9 iron. Now when you go to a downhill lie you double that, meaning 2 combinations. Obviously using the same math above for a typical lie settings you’ll run across: Flat, downhill, uphill, higher left foot, higher right foot, you will have a total of 1 swing combination for each lie. Meaning a total of 5 swing combinations.

          So now it is simple math. Is it easier to learn and use 30 different swing combinations using a traditional setup, or is it easier to learn and use 5 swing combinations with single length clubs?

          • Brian

            May 28, 2016 at 11:03 am

            This was my point. I don’t I agree with the 5 swing combinations, but I definitely agree that it isn’t “one swing” like the SL concept advocates want to believe. Lie and the shot required dictates set up.
            I tend to believe, a ball 1″, 2″ 3″, and 4″ below your feet, would require 4 different swings, since the angle has changed four times with a club of the same length.
            Like I stated, non pro or against, whatever works for the golfer. I’m just stated that there isn’t one set up and one swing in the Sl iron concept.

I want to used these as the heads for a single (or perhaps double, long +med & short+wedges) length set. Coincidentally, these are the same irons that Dechambeau used to make his first real set of single length clubs, so I know it can be done. Thank you Mr. Wood. Your reputation precedes you and I look forward to your contributions to this great site!

    • Petet

      May 25, 2016 at 1:08 pm

      Scudder,
      It is amazing to me that the industry is a-buzz since DeChambeau appeared on the scene with his custom made SL clubs. You would think he invented the things (he didn’t btw–the concept has been around for longer than he has been on this earth). If you are interested, there is a huge body of knowledge that is out on the web regarding SL clubs. However, your expertise only seems to go so far as trotting out your passing knowledge of a few failed golf club experiments. Do you know why they failed? Or is that all you need to know, that they failed?

      Once you know why things fail, you can adjust for those issues. Where would we be without Edison’s years of abject failures with the light bulb? Yet light bulbs are ubiquitous now, aren’t they? Bet you even have one or two in your home.

      Current SL iron sets have been pretty well designed to allow for many of these issues (Wishon’s Sterlings, and Value Golf’s Pinkhawks). Each one takes a slightly different approach, but they both have good working products. I am a clubmaker with over 20 years of experience and have been toying with this idea for quite awhile. However, I didn’t attempt to try and build a set because components didn’t exist that would allow one to create a set that would to do this. Customizing a current set required too much welding/grinding to make it worthwhile. Now there are off the shelf sets and also component sets available.

      I personally play a set of Pinhawks, 5-PW. I have an additional 54 degree gap/sand, and a 58 sand/lob. The 5-PW and 54 are all same length/swingweight, MOI. The 58 is a little shorter at an inch over standard, which is what I have played my standard clubs at all these years. My driver and three wood are 43.5 and 42.5. My hybrids are all same length at 40 inches. I have very reasonable 10-15 yard gaps between every club. I have no problem playing competitively and carry a 9 handicap. You simply make the same swing with each iron and the 5 degree loft increments take care of the distance. I will note that as someone else stated above, you still have to have a repeatable swing to play good golf, regardless of whether or not you use SL or standard golf clubs. SL simply takes a few more of the variables out of your game in the are of iron shots.

      BTW–to those out there that still talk about muscle memory: the whole issue of muscle memory is bogus. Read an article or two on brain science. Muscles don’t store memory. Period. Brains create neuronal patterns that govern muscle movement. Words have real meaning, and punctuation matters! Educate yourself. Remember the old saying: it is better to be thought a fool than to open your mouth (or write an editorial) and remove all doubt.

    Personally I like clubs that change length to loft – gives one a lot more creative options when in tricky situations – for example, taking a shorter club and hooding the club face and playing it back in your stance; or taking a longer club and choking up on it and making a smooth swing for a lower flight; or even taking a longer club when the ball is below your feet and taking less of a swing …

    I think single length irons are the best way to go for golf, the distance claims made by club companies today are getting outrageous. I hit a Wishon single length 7 iron against my ’16 Apex Pros and a Hogan Radial 7 iron. The distances were within a yard of each other. But to have the same swing, same set up every time you go to hit a ball. That’s the way to go, especially for amateur golfers. Less to worry about and an easier way into the game for many. I bet many of the detractors on here have never hit a SLI (single length iron) and would venture that once fitted for a set they would have better ball striking and flight over the set that they currently use.

    Paul thanks for the technical article, unfortunately too many people refuse to see change as a good thing and I don’t see this SLI becoming mainstream although it would probably be the best thing out there for growing the game of golf.

    • Hawk

      May 24, 2016 at 3:44 pm

      There is no reason why this can’t be mainstream. It would be very easy to base a SL set off the current industry standard 7 iron length and the industry standard 7 iron lie. Based on that, you can easily create a mass market single length set that a vast majority of golfers could fit into.

      Considering the argument of “getting fit” yet so many still play standard length anyways, the argument for needing to be fit, is mute.

      I think OEMs are afraid to produce a set because it would change the golf equipment landscape if it actually caught on and took off.

      • Shanks

        May 24, 2016 at 4:41 pm

        I couldn’t agree more. The industry has resorted to jacking lofts to “promise” more yardage out of every new set. While single length wouldn’t cure this it would help change the way a lot of people think about approaching the game from an equipment perspective.

  32. Matty

    May 24, 2016 at 1:14 pm

    IMO, it’s probably best to have 37 or 37.25 inches on the 4-9 irons and about 35.25 or 35.5 inches on the wedges instead of the Dechambeau method of having 37.5 inches on all irons and wedges.

  33. Chris

    May 24, 2016 at 12:36 pm

    Great article. I have been studying and tinkering with this as well. I like the fact that you are considering a more practical swing weight measurement, from a point between the hands, rather than 14″ fulcrum as all SW scales measure. Good stuff!

    I agree that having single length irons that all require the same physical effort to swing will very likely result in improved consistency in tempo, ball striking and distance for a golfer.
    I would love to have a set like this.
    The article does acknowledge the difference between “ClubHead MOI” and Club MOI which is a good thing because the MOI term is frequently used in the “press” w/o indication of which MOI is being referenced.
    I would be really interested in knowing how one goes about making a set of clubs that are BOTH “Club MOI” and “Club Swing weight” matched while being same length; assuming that this really means the set of irons are all the same length, swing weight AND all have the same Club MOI in kg per cm squared w/o differing shaft bend profiles between clubs in the set. That would be quite a feat.

    I would guess that every component used to build the club: Grip, shaft and head would need to be easily controlled for weight all w/o impacting shaft flex / bend profile between clubs.
    PXG Iron heads look like they have enough small weight inserts that may permit post head manufacture influence on the iron “head weight” and “iron head MOI”.
    This would NEVER fit the off the shelf club retail, sell to the sheeple, model and would thus need to be rendered insignificant or blasphemy via “expert testimony to the contrary” or blogology.

    • Paul Wood

      May 24, 2016 at 2:10 pm

      Richard, if we were to build a set from the ground up, then it is somewhat easy to match Club MOI, Club Swing Weight and Club Mass with a single length iron set. We would design each head at the same mass. We could actually use the same shaft and grip on each club. What is a lot more challenging is trying to take an existing set and modify them to be single length. The question of whether people would swing each club in such a set the same is an interesting one to me.

      • Richard Seepaul

        May 25, 2016 at 3:23 pm

        Fair enough, you need to control every aspect of every component used in the build.
        If you can’t then there are compromises to be made by both sides; customer and service provider.

    I strongly believe an average player will benefit more from a single length iron vs a high swing speed player. A club builder or an engineer may consider many things you just listed such as MOI, Swingweight, Projecting, Spin, Swing Plane, Angle of Attack, etc. But, for an average player there really is the one major concern I believe. That is the club contact. Speaking from my own experience, hitting the ball consistently to get it up in the air was the single most challenge when I first started this game. Nothing else mattered more for than to fly the ball in the air rather than rolling it on the ground. 🙂 Distance or anything else was a secondary. But, having to adjust different iron lengths, ball positions, different swing paths, etc just complicated the matters a lot as a beginner. We just had to accept that fact a golf is hard to learn, and many indeed gave up during the process. But, was there a real/tangible benefit in mastering all those different lengths and added complications that comes from those, I must ask.

    Come to think of it. I can see one economic reason why the club builders/manufactures may prefer non-single length irons. Beside all MOI, angle of attach, etc, etc, the single iron set will use more of the raw materials. One may say, it involves more research to produce non-single length irons, but at this point when non-single length irons are so well established and when the single length is the new thing. I think there is research cost on single length. And, for the manufacturing stand point, also the single length is slightly more costlier to produce because they use more steel. So from what I am thinking is that… I think many club builders see that there will be benefit from single length irons for some golf populations, but hesitant to jump onto the wagon because they are not sure if there really is enough demand to justify the added expenses.

    Hi Paul,

    I’d love to see PING take a shot at making a customer order only single length set, particularly with the upcoming iBlade release (maybe the SL concept would work better with the i’s, so you’d have more control over trajectory in the long irons). It would be a more conservative way to gauge interest in the concept, though I suppose the R&D costs could be prohibitive.

    With your advanced usage of CTP’s at PING, an outsider such as myself sees the possibility of weight matching, as well as the other factors you mentioned, very possible to do single length sets. I think many of us are just waiting for a major OEM such as yourself to go ahead with it. Being a PING man myself, I want it to be you guys!

      Alex, we’re looking into it. In theory we can process such an order through our WRX department (the name similarity is purely coincidental). It’s challenging for the club builders, so we’re trying to build some guidelines on what we can do and can’t do and what’s reasonable for the customer to expect out of the set. Our wide range of CTP weights does help a lot in this case. In my experimental set, the only club that required serious grinding to bring the weight down was the pitching wedge.

        That to me would be good reason to play Ping long term and not changing to other brands – currently playing Ping irons.

    man, the single length iron talk is quickly being beaten to death. I am rather over the slew of articles about this, topic not only on Wrx but every golf publication, seeing as only a fraction of a fraction of the golfing population would marginally benefit from this financially and time consuming experiment.

      Respectfully, do you have any research to validate your position or is it based on your (I will grant honestly experienced) opinion?

      Might it be possible that many who only occasionally play golf, or many of those who have tried and given up, would benefit from a much simpler and achievable learning curve?

      Perhaps only a tiny percentage of devoted golf amateurs and touring professionals would benefit from single length clubs. But I assure you, that, as a novice golfer, I really want to get a set of single length left handed irons to learn with.

      Having been a high performing amateur athlete in two unrelated sports, I know that the secret to high performance is training ones body to do simple things so well it becomes unconscious. Instead of learning eight different ways to swing my irons, each only a half inch different from one another, I would rather learn one way to swing all of them.

      I think it makes more sense for me to learn one good swing very well and conform my clubs to my swing than to take someone else’s opinion of how long eight clubs should be and try to memorize eight different swings to conform to that strangers opinion.

Vincenzi’s 2024 Texas Children’s Houston Open betting preview

Published

on

As the Florida swing comes to an end, the PGA Tour makes its way to Houston to play the Texas Children’s Houston Open at Memorial Park Golf Course.

This will be the fourth year that Memorial Park Golf Course will serve as the tournament host. The event did not take place in 2023, but the course hosted the event in 2020, 2021 and 2022.

Memorial Park is a par-70 layout measuring 7,432 yards and features Bermudagrass greens. Historically, the main defense for the course has been thick rough along the fairways and tightly mown runoff areas around the greens. Memorial Park has a unique setup that features three Par 5’s and five Par 3’s.

The field will consist of 132 players, with the top 65 and ties making the cut. There are some big names making the trip to Houston, including Scottie Scheffler, Wyndham Clark, Tony Finau, Will Zalatoris and Sahith Theegala.

Past Winners at Memorial Park

  • 2022: Tony Finau (-16)
  • 2021: Jason Kokrak (-10)
  • 2020: Carlos Ortiz (-13)

In this article and going forward, I’ll be using the Rabbit Hole by Betsperts Golf data engine to develop my custom model. If you want to build your own model or check out all of the detailed stats, you can sign up using promo code: MATTVIN for 25% off any subscription package (yearly is best value). 

Key Stats For Memorial Park

Let’s take a look at several metrics for Memorial Park to determine which golfers boast top marks in each category over their last 24 rounds:

Strokes Gained: Approach

Memorial Park is a pretty tough golf course. Golfers are penalized for missing greens and face some difficult up and downs to save par. Approach will be key.

Total Strokes Gained: Approach per round in past 24 rounds:

  1. Tom Hoge (+1.30)
  2. Scottie Scheffler (+1.26)
  3. Keith Mitchell (+0.97) 
  4. Tony Finau (+0.92)
  5. Jake Knapp (+0.84)

Strokes Gained: Off the Tee

Memorial Park is a long golf course with rough that can be penal. Therefore, a combination of distance and accuracy is the best metric.

Total Strokes Gained: Off the Tee per round in past 24 rounds:

  1. Scottie Scheffler (+0.94)
  2. Kevin Dougherty (+0.93)
  3. Cameron Champ (+0.86)
  4. Rafael Campos (+0.84)
  5. Si Woo Kim (+0.70)

Strokes Gained Putting: Bermudagrass + Fast

The Bermudagrass greens played fairly fast the past few years in Houston. Jason Kokrak gained 8.7 strokes putting on his way to victory in 2021 and Tony Finau gained in 7.8 in 2022.

Total Strokes Gained Putting (Bermudagrass) per round past 24 rounds (min. 8 rounds):

  1. Adam Svensson (+1.27)
  2. Harry Hall (+1.01)
  3. Martin Trainer (+0.94)
  4. Taylor Montgomery (+0.88)
  5. S.H. Kim (+0.86)

Strokes Gained: Around the Green

With firm and undulating putting surfaces, holding the green on approach shots may prove to be a challenge. Memorial Park has many tightly mowed runoff areas, so golfers will have challenging up-and-down’s around the greens. Carlos Ortiz gained 5.7 strokes around the green on the way to victory in 2020.

Total Strokes Gained: Around the Green per round in past 24 rounds:

  1. Mackenzie Hughes (+0.76)
  2. S.H. Kim (+0.68)
  3. Scottie Scheffler (+0.64)
  4. Jorge Campillo (+0.62)
  5. Jason Day (+0.60)

Strokes Gained: Long and Difficult

Memorial Park is a long and difficult golf course. This statistic will incorporate players who’ve had success on these types of tracks in the past. 

Total Strokes Gained: Long and Difficult in past 24 rounds:

  1. Scottie Scheffler (+2.45)
  2. Ben Griffin (+1.75)
  3. Will Zalatoris (+1.73)
  4. Ben Taylor (+1.53)
  5. Tony Finau (+1.42)

Course History

Here are the players who have performed the most consistently at Memorial Park. 

Strokes Gained Total at Memorial Park past 12 rounds:

2024 Texas Children’s Houston Open Picks

Will Zalatoris +2000 (Caesars)

Scottie Scheffler will undoubtedly be difficult to beat this week, so I’m starting my card with someone who I believe has the talent to beat him if he doesn’t have his best stuff.

Will Zalatoris missed the cut at the PLAYERS, but still managed to gain strokes on approach while doing so. In an unpredictable event with extreme variance, I don’t believe it would be wise to discount Zalatoris based on that performance. Prior to The PLAYERS, the 27-year-old finished T13, T2 and T4 in his previous three starts.

Zalatoris plays his best golf on long and difficult golf courses. In his past 24 rounds, he ranks 3rd in the category, but the eye test also tells a similar story. He’s contended at major championships and elevated events in the best of fields with tough scoring conditions.  The Texas resident should be a perfect fit at Memorial Park Golf Club.

Alex Noren +4500 (FanDuel)

Alex Noren has been quietly playing some of his best golf of the last half decade this season. The 41-year-old is coming off back-to-back top-20 finishes in Florida including a T9 at The PLAYERS in his most recent start.

In his past 24 rounds, Noren ranks 21st in the field in Strokes Gained: Off the Tee, 30th in Strokes Gained: Around the Green, 25th in Strokes Gained: Total on long and difficult courses and 21st in Strokes Gained: Putting on fast Bermudagrass greens.

In addition to his strong recent play, the Swede also has played well at Memorial Park. In 2022, Noren finished T4 at the event, gaining 2.2 strokes off the tee and 7.0 strokes on approach for the week. In his two starts at the course, he’s gained an average of .6 strokes per round on the field, indicating he is comfortable on these greens.

Noren has been due for a win for what feels like an eternity, but Memorial Park may be the course that suits him well enough for him to finally get his elusive first PGA Tour victory.

Mackenzie Hughes +8000 (FanDuel)

Mackenzie Hughes found himself deep into contention at last week’s Valspar Championship before faltering late and finishing in a tie for 3rd place. While he would have loved to win the event, it’s hard to see the performance as anything other than an overwhelming positive sign for the Canadian.

Hughes has played great golf at Memorial Park in the past. He finished T7 in 2020, T29 in 2021 and T16 in 2022. The course fit seems to be quite strong for Hughes. He’s added distance off the tee in the past year or and ranks 8th in the field for apex height, which will be a key factor when hitting into Memorial Park’s elevated greens with steep run-off areas.

In his past 24 rounds, Hughes is the best player in the field in Strokes Gained: Around the Greens. The ability to scramble at this course will be extremely important. I believe Hughes can build off of his strong finish last week and contend once again to cement himself as a President’s Cup consideration.

Akshay Bhatia +8000 (FanDuel)

Akshay Bhatia played well last week at the Valspar and seemed to be in total control of his golf ball. He finished in a tie for 17th and shot an impressive -3 on a difficult Sunday. After struggling Thursday, Akshay shot 68-70-68 in his next three rounds.

Thus far, Bhatia has played better at easier courses, but his success at Copperhead may be due to his game maturing. The 22-year-old has enormous potential and the raw talent to be one of the best players in the world when he figures it all out.

Bhatia is a high upside play with superstar qualities and may just take the leap forward to the next stage of his career in the coming months.

Cameron Champ +12000 (FanDuel)

Cameron Champ is a player I often target in the outright betting market due to his “boom-or-bust” nature. It’s hard to think of a player in recent history with three PGA Tour wins who’s been as inconsistent as Champ has over the course of his career.

Despite the erratic play, Cam Champ simply knows how to win. He’s won in 2018, 2019 and 2021, so I feel he’s due for a win at some point this season. The former Texas A&M product should be comfortable in Texas and last week he showed us that his game is in a pretty decent spot.

Over his past 24 rounds, Champ ranks 3rd in Strokes Gained: Off the Tee and 30th in Strokes Gained: Total on long and difficult courses. Given his ability to spike at any given time, Memorial Park is a good golf course to target Champ on at triple digit odds.

Robert MacIntyre +12000 (FanDuel)

The challenge this week is finding players who can possibly beat Scottie Scheffler while also not dumping an enormous amount of money into an event that has a player at the top that looks extremely dangerous. Enter McIntyre, who’s another boom-or-bust type player who has the ceiling to compete with anyone when his game is clicking on all cylinders.

In his past 24 rounds, MacIntyre ranks 16th in the field in Strokes Gained: Off the Tee, 17th in Strokes Gained: Around the Green and 10th in Strokes Gained: Total on long and difficult courses.

MacIntyre’s PGA Tour season has gotten off to a slow start, but he finished T6 in Mexico, which is a course where players will hit driver on the majority of their tee shots, which is what we will see at Memorial Park. Texas can also get quite windy, which should suit MacIntyre. Last July, the Scot went toe to toe with Rory McIlroy at the Scottish Open before a narrow defeat. It would take a similar heroic effort to compete with Scheffler this year in Houston.

Ryan Moore +15000 (FanDuel)

Ryan Moore’s iron play has been absolutely unconscious over his past few starts. At The PLAYERS Championship in a loaded field, he gained 6.1 strokes on approach and last week at Copperhead, he gained 9.0 strokes on approach.

It’s been a rough handful of years on Tour for the 41-year-old, but he is still a five-time winner on the PGA Tour who’s young enough for a career resurgence. Moore has chronic deterioration in a costovertebral joint that connects the rib to the spine, but has been getting more consistent of late, which is hopefully a sign that he is getting healthy.

Veterans have been contending in 2024 and I believe taking a flier on a proven Tour play who’s shown signs of life is a wise move at Memorial Park.

Opinion & Analysis

Ryan: Why the race to get better at golf might be doing more harm than good

Published

on

B.F. Skinner was one of the most important psychologists of the 20th century, developing the foundation of the development of reinforcement, and in doing so, creating the concept of behaviorism. In simple terms, this means that we are conditioned by our habits. In practical terms, it explains the divide between the few and far between elite instructors and college coaches.

To understand the application, let’s quickly review one of B.F. Skinner’s most important experiments; superstitions in the formation of behavior by pigeons. In this experiment, food was dispensed to pigeons at random intervals. Soon, according to Skinner, the pigeons began to associate whatever action they were doing at the time of the food being dispensed. According to Skinner, this conditioned that response and soon, they simply haphazardly repeated the action, failing to distinguish between cause and correlation (and in the meantime, looking really funny!).

Now, this is simply the best way to describe the actions of most every women’s college golf coach and too many instructors in America. They see something work, get positive feedback and then become conditioned to give the feedback, more and more, regardless of if it works (this is also why tips from your buddies never work!).

Go to a college event, particularly a women’s one, and you will see coaches running all over the place. Like the pigeons in the experiment, they have been conditioned into a codependent relationship with their players in which they believe their words and actions, can transform a round of golf. It is simply hilarious while being equally perturbing

In junior golf, it’s everywhere. Junior golf academies make a living selling parents that a hysterical coach and over-coaching are essential ingredients in your child’s success.

Let’s be clear, no one of any intellect has any real interest in golf — because it’s not that interesting. The people left, including most coaches and instructors, carve out a small fiefdom, usually on the corner of the range, where they use the illusion of competency to pray on people. In simple terms, they baffle people with the bullshit of pseudo-science that they can make you better, after just one more lesson.

The reality is that life is an impromptu game. The world of golf, business, and school have a message that the goal is being right. This, of course, is bad advice, being right in your own mind is easy, trying to push your ideas on others is hard. As a result, it is not surprising that the divorce rate among golf professionals and their instructors is 100 percent. The transfer rate among college players continues to soar, and too many courses have a guy peddling nefarious science to good people. In fact, we do at my course!

The question is, what impact does all this have on college-age and younger kids? At this point, we honestly don’t know. However, I am going to go out on a limb and say it isn’t good.

Soren Kierkegaard once quipped “I saw it for what it is, and I laughed.” The actions of most coaches and instructors in America are laughable. The problem is that I am not laughing because they are doing damage to kids, as well as driving good people away from this game.

The fact is that golfers don’t need more tips, secrets, or lessons. They need to be presented with a better understanding of the key elements of golf. With this understanding, they can then start to frame which information makes sense and what doesn’t. This will emancipate them and allow them to take charge of their own development.

Vincenzi’s 2024 Valspar Championship betting preview: Elite ballstrikers to thrive at Copperhead

Published

on

The PGA TOUR will stay in Florida this week for the 2024 Valspar Championship.

The Copperhead Course at Innisbrook Resort is a par 71 measuring 7,340 yards and features Bermudagrass greens overseeded with POA. Infamous for its difficulty, the track will be a tough test for golfers as trouble lurks all over the place. Holes 16, 17 and 18 — also known as the “Snake Pit” — make up one of the toughest three-hole stretches in golf and should lead to a captivating finish on Sunday.

The field is comprised of 156 golfers teeing it up. The field this week is solid and is a major improvement over last year’s field that felt the impact of players skipping due to a handful of “signature events” in a short span of time. 

Past Winners at Valspar Championship

  • 2023: Taylor Moore (-10)
  • 2022: Sam Burns (-17)
  • 2021: Sam Burns (-17)
  • 2019: Paul Casey (-8)
  • 2018: Paul Casey (-10)
  • 2017: Adam Hadwin (-14)
  • 2016: Charl Schwartzel (-7)
  • 2015: Jordan Spieth (-10)

In this article and going forward, I’ll be using the Rabbit Hole by Betsperts Golf data engine to develop my custom model. If you want to build your own model or check out all of the detailed stats, you can sign up using promo code: MATTVIN for 25% off any subscription package (yearly is best value). 

Key Stats For Copperhead

1. Strokes Gained: Approach

Strokes Gained: Approach grades out as the most important statistic once again this week. Copperhead really can’t be overpowered and is a second-shot golf course.

Total SG: Approach Over Past 24 Rounds (per round)

  1. Tony Finau (+.90)
  2. Nick Taylor (+.81)
  3. Justin Thomas (+.77)
  4. Greyson Sigg (+.69)
  5. Christiaan Bezuidenhout (+.67)

2. Good Drive %

The long hitters can be a bit limited here due to the tree-lined fairways and penal rough. Playing from the fairways will be important, but laying back too far will cause some difficult approaches with firm greens that may not hold shots from long irons.

Golfers who have a good balance of distance and accuracy have the best chance this week.

Good Drive % Over Past 24 Rounds

  1. Brice Garnett (+91.3%) 
  2. Zach Johnson (+91.1%)
  3. Sam Ryder (+90.5%)
  4. Ryan Moore (+90.4%)
  5. Aaron Rai (+89.7%)

3. Strokes Gained: Ball Striking

Adding ball-striking puts even more of a premium on tee-to-green prowess in the statistical model this week. Golfers who rank highly in ball-striking are in total control of the golf ball which is exceedingly important at Copperhead.

SG: Ball Striking Over Past 24 Rounds:

  1. Xander Schauffele (+1.32)
  2. Keith Mitchell (+1.29)
  3. Tony Finau (+1.24)
  4. Cameron Young (+1.17) 
  5. Doug Ghim (+.95)

4. Bogey Avoidance

With the conditions likely to be difficult, avoiding bogeys will be crucial this week. In a challenging event like the Valspar, oftentimes the golfer who is best at avoiding mistakes ends up on top.

Gritty golfers who can grind out difficult pars have a much better chance in an event like this than a low-scoring birdie-fest.

Bogey Avoidance Over Past 24 Rounds

  1. Brice Garnett (+9.0)
  2. Xander Schauffele (+9.3)
  3. Austin Cook (+9.7) 
  4. Chesson Hadley (+10.0)
  5. Greyson Sigg (+10.2)

5. Strokes Gained: Total in Difficult Conditions

Conditions will be tough this week at Copperhead. I am looking for golfers who can rise to the occasion if the course plays as difficult as it has in the past.

Strokes Gained: Total in Difficult Conditions Over Past 24 rounds

  1. Xander Schauffele (+1,71) 
  2. Min Woo Lee (+1.39)
  3. Cameron Young (+1.27)
  4. Jordan Spieth (+1.08)
  5. Justin Suh (+.94)

6. Course History

That statistic will tell us which players have played well at Copperhead in the past.

Course History Over Past 24 rounds

  1. Patrick Cantlay (+3.75) 
  2. Sam Burns (+2.49)
  3. Davis Riley (+2.33)
  4. Matt NeSmith (+2.22)
  5. Jordan Spieth (+2.04)

The Valspar Championship Model Rankings

Below, I’ve compiled overall model rankings using a combination of the five key statistical categories previously discussed — SG: Approach (27%), Good Drive % (15%), SG: BS (20%), Bogeys Avoided (13%), Course History (13%) Strokes Gained: Total in Difficult Conditions (12%).

  1. Xander Schauffele
  2. Doug Ghim
  3. Victor Perez
  4. Greyson Sigg
  5. Ryan Moore
  6. Tony Finau
  7. Justin Thomas
  8. Sam Ryder
  9. Sam Burns
  10. Lucas Glover

2024 Valspar Championship Picks

Justin Thomas +1400 (DraftKings)

Justin Thomas will be disappointed with his finish at last week’s PLAYERS Championship, as the past champion missed the cut despite being in some decent form heading into the event. Despite the missed cut, JT hit the ball really well. In his two rounds, the two-time major champion led the field in Strokes Gained: Approach per round.

Thomas has been up and down this season. He’s missed the cut in two “signature events” but also has finishes of T12 at the Arnold Palmer Invitational, T12 at the Waste Management Phoenix Open, T6 at the Pebble Beach AT&T Pro-Am and T3 at the American Express. In his past 24 rounds, he ranks 3rd in the field in Strokes Gained: Approach and 6th in Strokes Gained: Ball Striking in the field.

Thomas loves Copperhead. In his last three tries at the course, he’s finished T13, T3 and T10. Thomas would have loved to get a win at a big event early in the season, but avoidable mistakes and a balky putter have cost him dearly. I believe a trip to a course he loves in a field he should be able to capitalize on is the right recipe for JT to right the ship.

Christiaan Bezuidenhout +6000 (FanDuel)

Christiaan Bezuidenhout is playing spectacular golf in the 2024 season. He finished 2nd at the American Express, T20 at Pebble Beach and T24 at the Genesis Invitational before finishing T13 at last week’s PLAYERS Championship.

In his past 24 rounds, the South African ranks 3rd in the field in Strokes Gained: Approach and 26th in Strokes Gained: Ball Striking. Bezuidenhout managed to work his way around TPC Sawgrass last week with minimal damage. He only made five bogeys in the entire week, which is a great sign heading into a difficult Copperhead this week.

Bezuidenhout is winless in his PGA Tour career, but certainly has the talent to win on Tour. His recent iron play tells me that this week could be a breakthrough for the 35-year-old who has eyes on the President’s Cup.

Doug Ghim +8000 (FanDuel)

Doug Ghim has finished in the top-16 of his past five starts. Most recently, Ghim finished T16 at The PLAYERS Championship in a loaded field.

In his past 24 rounds, Ghim ranks 8th in Strokes Gained: Approach and 5th in Strokes Gained: Ball Striking. In terms of his fit for Copperhead, the 27-year-old ranks 12th in Bogey Avoidance and 7th in Strokes Gained: Total in Difficult Conditions, making him a great fit for the course.

Ghim has yet to win on Tour, but at one point he was the top ranked Amateur golfer in the world and played in the 2017 Arnold Palmer Cup and 2017 Walker Cup. He then won the Ben Hogan award for the best male college golfer in 2018. He certainly has the talent, and there are signals aplenty that his talent in ready to take him to the winner’s circle on the PGA Tour.

Sepp Straka +8000 (BetRivers)

Sepp Straka is a player who’s shown he has the type of game that can translate to a difficult Florida golf course. The former Presidents Cup participant won the 2022 Honda Classic in tough conditions and should thrive with a similar test at Copperhead.

It’s been a slow 2024 for Straka, but his performance last week at the PLAYERS Championship surely provides some optimism. He gained 5.4 strokes on approach as well as 1.88 strokes off the tee. The tee-to-green game Straka showed on a course with plenty of danger demonstrates that he can stay in control of his golf ball this week.

It’s possible that the strong performance last week was an outlier, but I’m willing to bet on a proven winner in a weaker field at a great number.

Victor Perez +12000 (FanDuel)

Victor Perez is no stranger to success in professional golf. The Frenchman has three DP World Tour wins including a Rolex Series event. He won the 2019 Alfred Dunhill Links Championship, as well as the 2023 Abu Dhabi HSBC Championship, which are some big events.

Perez earned his PGA Tour card this season and enters the week playing some fantastic golf. He finished in a tie for 16th in Florida at the Cognizant Classic and then tied for third in his most recent start at the Puerto Rico Open.

In his past 24 rounds in the field, Perez ranks 11th in Strokes Gained: Approach, 1oth in Strokes Gained: Ball Striking, 6th in Good Drive % and 15th in Bogey Avoidance.

Perez comes in as a perfect fit for Copperhead and offers serious value at triple-digit odds.
