The Wedge Guy: An analysis of spin

Published

on

As long as I have been in the wedge design business and writing my blog (over 700 articles!), I have received hundreds of questions like, “How do I get more spin with my wedge shots?” The truth is that there is a very complex answer to what appears to be a simple question. So, let’s dive into it today.

We all know those golfers who seem to spin the ball easily, and others who just do not generate much spin. And of course, we watch the tour professionals every week hit a wide variety of shots with varying amounts of spin. How do they do that?

I believe that very few recreational golfers really understand the dynamics of what makes a golf ball spin, so let me see if I can’t break it down into pieces here.

First, understand that the amount of spin imparted to the golf ball is affected by six things. Those six factors are (in no particular order of importance):

  1. The quality of grooves on the face of the wedge
  2. The loft of the wedge
  3. The speed of the clubhead at impact
  4. The path of the clubhead as it approaches the ball
  5. The specific “quality” of impact . . . and
  6. The ball itself

The great thing is that you have control over all these factors, though some are easier to improve than others. Let’s examine each, but in the order of easiest to most difficult.

The ball. This is one very simple way to improve the spin you get with your wedge shots. All of the more premium balls feature a softer urethane cover that allows the club to grip the ball better. The harder, and usually less expensive, balls typically have a Surlyn cover which is more durable but doesn’t allow as much spin. You should experiment with various balls to see which gives you the optimum combination of distance and spin.

The grooves. One of the major wedge brands is now reporting that your wedges begin to lose their ability to spin the ball after as few as 50 rounds of golf. If you practice a lot, that number would surely be lower. I can’t comment to these numbers, but I will say that, very simply, if you are playing a wedge that you’ve had for years, it’s likely costing some of your spin. That said, I have seen golfers who play badly worn wedges that seem to be able to spin the ball at will.

The loft of the wedge. It stands to reason that your 56-degree wedge will impart more spin than your pitching or gap wedge, because it has more loft. And your 60-degree will give you even more. So, generally speaking, when you want more spin for a shot, choose a higher lofted wedge.

Now we get into the technique aspects of generating improved spin. Let’s examine these.

Clubhead speed. It’s pretty simple physics, actually. Given all the other parameters the same, the faster the clubhead is moving through impact, the more spin will be generated. That’s one reason why most of us amateurs should not lay up on par fives and long par fours to that awkward 30- to 50-yard range. Not only is it an in-between swing we probably don’t practice, but you don’t have the clubhead speed at that range to generate optimum spin.

Angle of approach. We have read thousands of times that you have to “hit down” on the ball to get spin. Well, that’s true, but can also be misleading. I mean, the ball is sitting on the ground – how would you hit “up” on it anyway? I contend that’s practically impossible. When you are hitting practice shots, you want to think of making contact with the ball…and then the turf – it’s that simple. The thought of hitting “down” on the ball causes many amateurs to make an overly steep swing path, which is undesirable. Just realize that you do not need to “help” your wedge get the ball in the air. Club designers have given it loft to make sure it will get in the air. All you need to do is swing the club through the ball and make sure the clubhead is traveling slightly downward at impact.

Quality of impact. This aspect of the spin equation takes into account the ability to get a clean face on the ball, not compromised by grass or moisture. And it also considers exactly where on the clubface you make contact, a subject on which I have personally conducted quite a bit of research. In fact, from my experience, this is possibly the most important and misunderstood aspect of good wedge play and is probably worthy of an entire article.

So, think about these other five aspects of spin for a bit. I’ll dive into that subject next week, and we’ll examine impact in detail.

    I agree with Matt,
    of course better ball, better grooves but spin comes from 2 essential elements: Speed and friction.
    Maximum friction is at 46* of dynamic loft. A putter has zero spin and at the other spectrum a 90* wedge would have zero spin.
    Max friction is at 45* so maybe a gap with 3* negative angle of attack would generate more spin but go to far. So more loft will allow to have more speed to get the job done.

    For an older golfer, I still can manage to spin the ball pretty well. Even on some shorter chip shots around the green where there isn’t a lot of club head speed. I have always felt that one of the factors influencing spin was acceleration through the ball.

    Doesn’t hitting the ball cleanly but slight low on the face impart more spin? Like one groove below the sweetspot?

    Also I read once a 58* wedge imparts the most spin for the majority of players, although I am sure this varies a bit based on technique.

    Of course point Number One is… urethane-cover balls. The revolution in equipment technology that produced, for elite players, acceptable spin in a solid-core “distance” golf ball.

    Don’t think its true that more loft always imparts more spin. There are diminishing returns as spin loft increases and spin will actually decrease at some point. Reasoning has to do with compression – the more glancing the blow is the less likely you are able to impart maximum spin. Its obviously going to depend on many delivery characteristics, but many people will spin their 56 more than their 60. In a related story – trackman shows wedge shots hit with draw spin actually have more backspin than those with fade spin.

      I agree. I find this to generally be true, but in terms of how the ball behaves once it hits the green you also have to factor in angle of descent.

Vincenzi’s LIV Golf Singapore betting preview: Course specialist ready to thrive once again

Published

on

After another strong showing in Australia, LIV Golf will head to Sentosa Golf Club in Singapore looking to build off of what was undoubtedly their best event to date.

Sentosa Golf Club sits on the southern tip of Singapore and is one of the most beautiful courses in the world. The course is more than just incredible scenically; it was also rated 55th in Golf Digest’s top-100 courses in 2022-2023 and has been consistently regarded as one of the best courses in Asia. Prior to being part of the LIV rotation, the course hosted the Singapore Open every year since 2005.

Sentosa Golf Club is a par 71 measuring 7,406 yards. The course will require precise ball striking and some length off the tee. It’s possible to go low due to the pristine conditions, but there are also plenty of hazards and difficult spots on the course that can bring double bogey into play in a hurry. The Bermudagrass greens are perfectly manicured, and the course has spent millions on the sub-air system to keep the greens rolling fast. I spoke to Asian Tour player, Travis Smyth, who described the greens as “the best [he’s] ever played.”

Davis Love III, who competed in a Singapore Open in 2019, also gushed over the condition of the golf course.

“I love the greens. They are fabulous,” the 21-time PGA Tour winner said.

Love III also spoke about other aspects of the golf course.

“The greens are great; the fairways are perfect. It is a wonderful course, and it’s tricky off the tee.”

“It’s a long golf course, and you get some long iron shots. It takes somebody hitting it great to hit every green even though they are big.”

As Love III said, the course can be difficult off the tee due to the length of the course and the trouble looming around every corner. It will take a terrific ball striking week to win at Sentosa Golf Club.

In his pre-tournament press conference last season, Phil Mickelson echoed many of the same sentiments.

“To play Sentosa effectively, you’re going to have a lot of shots from 160 to 210, a lot of full 6-, 7-, 8-iron shots, and you need to hit those really well and you need to drive the ball well.”

Golfers who excel from tee to green and can dial in their longer irons will have a massive advantage this week.

LIV Golf Singapore Picks

Sergio Garcia +3000 (DraftKings)

Sergio Garcia is no stranger to Sentosa Golf Club. The Spaniard won the Singapore Open in 2018 by five strokes and lost in a playoff at LIV Singapore last year to scorching hot Talor Gooch. Looking at the course setup, it’s no surprise that a player like Sergio has played incredible golf here. He’s long off the tee and is one of the better long iron players in the world when he’s in form. Garcia is also statistically a much better putter on Bermudagrass than he is on other putting surfaces. He’s putt extremely well on Sentosa’s incredibly pure green complexes.

This season, Garcia has two runner-up finishes, both of them being playoff losses. Both El Camaleon and Doral are courses he’s had success at in his career. The Spaniard is a player who plays well at his tracks, and Sentosa is one of them. I believe Sergio will get himself in the mix this week. Hopefully the third time is a charm in Singapore.

Paul Casey +3300 (FanDuel)

Paul Casey is in the midst of one of his best seasons in the five years or so. The results recently have been up and down, but he’s shown that when he’s on a golf course that suits his game, he’s amongst the contenders.

This season, Casey has finishes of T5 (LIV Las Vegas), T2 (LIV Hong Kong), and a 6th at the Singapore Classic on the DP World Tour. At his best, the Englishman is one of the best long iron players in the world, which makes him a strong fit for Sentosa. Despite being in poor form last season, he was able to fire a Sunday 63, which shows he can low here at the course.

It’s been three years since Casey has won a tournament (Omega Dubai Desert Classic in 2021), but he’s been one of the top players on LIV this season and I think he can get it done at some point this season.

Mito Pereira +5000 (Bet365)

Since Mito Pereira’s unfortunate demise at the 2022 PGA Championship, he’s been extremely inconsistent. However, over the past few months, the Chilean has played well on the International Series as well as his most recent LIV start. Mito finished 8th at LIV Adelaide, which was his best LIV finish this season.

Last year, Pereira finished 5th at LIV Singapore, shooting fantastic rounds of 67-66-66. It makes sense why Mito would like Sentosa, as preeminent ball strikers tend to rise to the challenge of the golf course. He’s a great long iron player who is long and straight off the tee.

Mito has some experience playing in Asia and is one of the most talented players on LIV who’s yet to get in the winner’s circle. I have questions about whether or not he can come through once in contention, but if he gets there, I’m happy to roll the dice.

Andy Ogletree +15000 (DraftKings)

Andy Ogletree is a player I expected to have a strong 2024 but struggled early in his first full season on LIV. After failing to crack the top-25 in any LIV event this year, the former U.S. Amateur champion finally figured things out, finished in a tie for 3rd at LIV Adelaide.

Ogletree should be incredible comfortable playing in Singapore. He won the International Series Qatar last year and finished T3 at the International Series Singapore. The 26-year-old was arguably the best player on the Asian Tour in 2023 and has been fantastic in the continent over the past 18 months.

If Ogletree has indeed found form, he looks to be an amazing value at triple-digit odds.

Ryan: Lessons from the worst golf instructor in America

Published

on

In Tampa, there is a golf course that boasts carts that do not work, a water range, and a group of players none of which have any chance to break 80. The course is overseen by a staff of crusty men who have succeeded at nothing in life but ending up at the worst-run course in America. However, this place is no failure. With several other local courses going out of business — and boasting outstanding greens — the place is booked full.

While I came for the great greens, I stayed to watch our resident instructor; a poor-tempered, method teacher who caters to the hopeless. At first, it was simply hilarious. However, after months of listening and watching, something clicked. I realized I had a front-row seat to the worst golf instructor in America.

Here are some of my key takeaways.

Method Teacher

It is widely accepted that there are three types of golf instructors: system teachers, non-system teachers, and method teachers. Method teachers prescribe the same antidote for each student based on a preamble which teachers can learn in a couple day certification.

Method teaching allows anyone to be certified. This process caters to the lowest caliber instructor, creating the illusion of competency. This empowers these underqualified instructors with the moniker of “certified” to prey on the innocent and uninformed.

The Cult of Stack and Jilt

The Stack and Tilt website proudly boasts, “A golfer swings his hands inward in the backswing as opposed to straight back to 1) create power, similar to a field goal kicker moving his leg in an arc and 2) to promote a swing that is in-to-out, which produces a draw (and eliminates a slice).”

Now, let me tell you something, there is this law of the universe which says “energy can either be created or destroyed,” so either these guys are defying physics or they have no idea what they are taking about. Further, the idea that the first move of the backswing determines impact is conjecture with a splash of utter fantasy.

These are the pontifications of a method — a set of prescriptions applied to everyone with the hope of some success through the placebo effect. It is one thing for a naive student to believe, for a golf instructor to drink and then dispel this Kool-Aid is malpractice.

Fooled by Randomness

In flipping a coin, or even a March Madness bet, there is a 50-50 chance of success. In golf, especially for new players, results are asymmetric. Simply put: Anything can happen. The problem is that when bad instructors work with high handicappers, each and every shot gets its own diagnosis and prescription. Soon the student is overwhelmed.

Now here’s the sinister thing: The overwhelming information is by design. In this case, the coach is not trying to make you better, they are trying to make you reliant on them for information. A quasi Stockholm syndrome of codependency.

Practice

One of the most important scientists of the 20th century was Ivan Pavlov. As you might recall, he found that animals, including humans, could be conditioned into biological responses. In golf, the idea of practice has made millions of hackers salivate that they are one lesson or practice session from “the secret.”

Sunk Cost

The idea for the worst golf instructor is to create control and dependency so that clients ignore the sunk cost of not getting better. Instead, they are held hostage by the idea that they are one lesson or tip away from unlocking their potential.

Cliches

Cliches have the effect of terminating thoughts. However, they are the weapon of choice for this instructor. Add some hyperbole and students actually get no information. As a result, these players couldn’t play golf. When they did, they had no real scheme. With no idea what they are doing, they would descend into a spiral of no idea what to do, bad results, lower confidence, and running back to the lesson tee from more cliches.

The fact is that poor instruction is about conditioning players to become reliant members of your cult. To take away autonomy. To use practice as a form of control. To sell more golf lessons not by making people better but through the guise that without the teacher, the student can never reach their full potential. All under the umbrella of being “certified” (in a 2-day course!) and a melee of cliches.

This of course is not just happening at my muni but is a systemic problem around the country and around the world, the consequences of which are giving people a great reason to stop playing golf. But hey, at least it’s selling a lot of golf balls…

Vincenzi’s 2024 Zurich Classic of New Orleans betting preview

Published

on

The PGA TOUR heads to New Orleans to play the 2023 Zurich Classic of New Orleans. In a welcome change from the usual stroke play, the Zurich Classic is a team event. On Thursday and Saturday, the teams play best ball, and on Friday and Sunday the teams play alternate shot.

TPC Louisiana is a par 72 that measures 7,425 yards. The course features some short par 4s and plenty of water and bunkers, which makes for a lot of exciting risk/reward scenarios for competitors. Pete Dye designed the course in 2004 specifically for the Zurich Classic, although the event didn’t make its debut until 2007 because of Hurricane Katrina.

Coming off of the Masters and a signature event in consecutive weeks, the field this week is a step down, and understandably so. Many of the world’s top players will be using this time to rest after a busy stretch.

However, there are some interesting teams this season with some stars making surprise appearances in the team event. Some notable teams include Patrick Cantlay and Xander Schauffele, Rory McIlroy and Shane Lowry, Collin Morikawa and Kurt Kitayama, Will Zalatoris and Sahith Theegala as well as a few Canadian teams, Nick Taylor and Adam Hadwin and Taylor Pendrith and Corey Conners.

Past Winners at TPC Louisiana

  • 2023: Riley/Hardy (-30)
  • 2022: Cantlay/Schauffele (-29)
  • 2021: Leishman/Smith (-20)
  • 2019: Palmer/Rahm (-26)
  • 2018: Horschel/Piercy (-22)
  • 2017: Blixt/Smith (-27)

2024 Zurich Classic of New Orleans Picks

Tom Hoge/Maverick McNealy +2500 (DraftKings)

Tom Hoge is coming off of a solid T18 finish at the RBC Heritage and finished T13 at last year’s Zurich Classic alongside Harris English.

This season, Hoge is having one of his best years on Tour in terms of Strokes Gained: Approach. In his last 24 rounds, the only player to top him on the category is Scottie Scheffler. Hoge has been solid on Pete Dye designs, ranking 28th in the field over his past 36 rounds.

McNealy is also having a solid season. He’s finished T6 at the Waste Management Phoenix Open and T9 at the PLAYERS Championship. He recently started working with world renowned swing coach, Butch Harmon, and its seemingly paid dividends in 2024.

Keith Mitchell/Joel Dahmen +4000 (DraftKings)

Keith Mitchell is having a fantastic season, finishing in the top-20 of five of his past seven starts on Tour. Most recently, Mitchell finished T14 at the Valero Texas Open and gained a whopping 6.0 strokes off the tee. He finished 6th at last year’s Zurich Classic.

Joel Dahmen is having a resurgent year and has been dialed in with his irons. He also has a T11 finish at the PLAYERS Championship at TPC Sawgrass which is another Pete Dye track. With Mitchell’s length and Dahmen’s ability to put it close with his short irons, the Mitchell/Dahmen combination will be dangerous this week.

Taylor Moore/Matt NeSmith +6500 (DraftKings)

Taylor Moore has quickly developed into one of the more consistent players on Tour. He’s finished in the top-20 in three of his past four starts, including a very impressive showing at The Masters, finishing T20. He’s also finished T4 at this event in consecutive seasons alongside Matt NeSmith.

NeSmith isn’t having a great 2024, but has seemed to elevate his game in this format. He finished T26 at Pete Dye’s TPC Sawgrass, which gives the 30-year-old something to build off of. NeSmith is also a great putter on Bermudagrass, which could help elevate Moore’s ball striking prowess.
