How to track some of the most important stats in golf

Published

on

I have been studying the game of golf from a statistical standpoint for 27 years. In 1992, I launched a new form of analysis that I called Strokes Lost and Saved, now known as Strokes Gained. My system was built around encouraging golf instructors and players to move away from the traditional, one-dimensional stats (fairways, GIR’s, sand saves and number of putts) to this much more accurate method. Traditional golf stats can be misleading as they give one-dimensional, yes/no answers to describe a complicated, multi-dimensional game.

The inability of these stats to shed light on performance is what motivated me to create ShotByShot.com, which gives golfers real insight and answers about their strengths and weaknesses with comparative data relevant to their handicap level. It’s a simple, powerful tool, but I’m often pressed for an even simpler solution by golf professionals, who ask:

“What is the most important stat in golf? If I were to get my players to keep ONE stat, what should it be?”

My quick, somewhat sharp-edged, answer to that question is: “If there were such an all-important stat, I would be out of business.” I guess I have mellowed, and can suggest a “starter stat” to provide instructors and golfers something simple that adds value: Have your players track their major ERRORS!

I realized years ago that frequency and severity of errors does more to establish every player’s scoring level than all of the good shots hit. Further, the ability to identify and limit these errors is the most efficient way to improve.

Below, I have defined the most frequent and costly errors in the game, and can provide the average frequency of these errors for the typical 80 and 90 shooters. This data comes from ShotByShot.com’s robust database of more than 250,000 rounds entered and analyzed. See how your game matches up over three to five rounds:

1. Driving errors. There are three types:

  • No Shot result: Drive hit out of play requiring an advancement shot to return to normal play.
  • Penalty-1 result: Hazard for unplayable lie.
  • OB/Lost result: Lost or out of bounds.

2. Short Game errors: Chip/pitch and sand shots (separately) from all positions within 50 yards of the hole that MISS the green.

3. Three-Putts: From within 20 feet of the hole or less.

In your next few rounds, track these four errors on four lines of a separate scorecard. For driving errors and 3-putts (within 20 feet), simply mark the holes where these mistakes occur. For chip/pitch and sand shots, mark the hole where each short game shot is successful (on the green) with a check and those that miss the green with an X. This way you will know the total number of shots in each short game category as well as the relative number of errors.

Compare your results from three to five rounds with the chart below and your major weakness should become clear. Work to mitigate that weakness and you will achieve meaningful improvement. Then repeat the process until you have NO major weakness in your game.

In 1989, Peter Sanders founded Golf Research Associates, LP, creating what is now referred to as Strokes Gained Analysis. His goal was to design and market a new standard of statistically based performance analysis programs using proprietary computer models. A departure from “traditional stats,” the program provided analysis with answers, supported by comparative data. In 2006, the company’s website, ShotByShot.com, was launched. It provides interactive, Strokes Gained analysis for individual golfers and more than 150 instructors and coaches that use the program to build and monitor their player groups. Peter has written, or contributed to, more than 60 articles in major golf publications including Golf Digest, Golf Magazine and Golf for Women. From 2007 through 2013, Peter was an exclusive contributor and Professional Advisor to Golf Digest and GolfDigest.com. Peter also works with PGA Tour players and their coaches to interpret the often confusing ShotLink data. Zach Johnson has been a client for nearly five years. More recently, Peter has teamed up with Smylie Kaufman’s swing coach, Tony Ruggiero, to help guide Smylie’s fast-rising career.

    Peter, I am interested in how this compares to GIR targets for 80s shooter. I am a mid-high 80s shooter struggling to get into low 80s. I have read other statisticians say GIR is the strongest correlation to score, and their analysis shows 8 GIR per round is general target to break 80. My personal stats also show the most correlation of GIR to score and I rarely hit that magic 8 number. This article has no mention of GIR. I tracked my stats versus these errors and the only shortcoming I see is I am about 5% off in the short game category – which is only about 1 shot per round. Is it viable to track the total errors per round – as one day may be driving, another short game, etc…This is really interesting material.

      Jason,
      GIR’s is the most valuable of the “Traditional”, one-dimensional stats and there generally is a direct correlation between # GIR’s and scoring. Further, you are barking… in the right direction with your goal of 8 GIR’s to break 80. In our database of 250,000+ rounds, the 79 shooter averages 8.3 GIR’s. That said, the game is a puzzle and there are many important pieces that must all fit together. If GIR’s were the tell all stat, I would not be in business. It is why I created ShotByShot.com and what is now called Strokes Gained to remove the mystery from golf stats.
      I hope this helps.

    ” that I called Strokes Lost and Saved, now known as Strokes Gained”
    So it was you who invented Strokes Gained not Mark Broadie? Does Mark Broadie know that he didn’t actually invent Stokes Gained ;-)?

    • Peter Sanders

      Jun 6, 2016 at 11:29 am

      ParHunter,
      Yes, I have spoken with him about it. Further in his book, he was careful to say that “…he implemented Strokes Gained in 2005…”

    My stats for my last round would be useless. I played 9 holes. 6/7 fairways. Gir 7/9. And 1.9 putts per hole. The course didnt maintain a bunker and it had lots of weeds in it and my laser picked up the weeds and not the stick. Laser said 170. I landed right in the middle and made double bogey. A few holes later i landed in a bunker that was full of rocks and wasn’t maintained so i picked up my ball and went backwards away from the hole (i didnt want to scratch my new wedge…) The whole area was bare and i skulled it over for another double bogey. Rest of my round was my best this season with a bogey and a two birdies. Maybe i should play better courses ????

    This analysis is sooooo true! The only thing keeping me from consistently shooting in the low 70’s to high 60’s are the 4-5 bad shots I hit per round. But if I play defensively trying not to hit those bad shots I will hit more of them. Seemingly a contradiction. Your thoughts Peter???

    • Peter Sanders

      Jun 6, 2016 at 9:21 am

      I understand, one cannot play defensively. My old pro taught me to look at it differently – to evaluate every shot opportunity as a green light (go for it), yellow light (play conservatively), or red light opportunity (play to avoid the error). Each of these situations simply help determine the target. Once the appropriate target is selected, the shot is executed full out without fear. Make sense?

      • Double Mocha Man

        Jun 6, 2016 at 11:17 am

        Yes, it does. Thanks. Wish I could be a teen again when I had no fear.

      Thanks Robert, I will have to fix that. When we added the approach shot feature last May to complete the entire Strokes Gained puzzle we raised the price. I have been at this for 27 year and need to cover my substantial costs at some point. Sorry.

        No problem, just wondering. Thanks for the response.

    The only stat that really matters is if there is more money in your wallet after your match then there was before.

    What is the difference between OB/Lost ball and No Shot Result?

    • Peter Sanders

      Jun 5, 2016 at 12:16 pm

      No shot is the least costly of the Driving errors. It is a ball hit to a position that requires some sort of advancement shot to return to normal play. Behind a tree, etc.
      OB/Lose is either Out of Bounds or a Lost ball – both stroke and distance penalties.

    How do you change your definition of each error for a player who shoots low 70s. I assuming driving stays the same, but how do you define an error in the short game area / 3 putts?

    • Peter Sanders

      Jun 5, 2016 at 12:18 pm

      Eric,
      I don’t change the definitions. If you shoot in the 70’s, a. well done and b. you should experience very few of these errors.

    2 questions:
    Why do 3 putts only matter within 20 feet? Is it normal to 3 putt outside of that range for people who shoot 80 and 90?

    Why do you select 50 yards as the short game range rather than looking at a normal GIR?

    Is the point just to show where you’re losing strokes that are easier to save?

    • Jim

      Jun 4, 2016 at 8:26 pm

      The tour average within 20 feet is 2 putts. Over 20 feet and the tour average begins to tic slowly over 2 putts. For example at 30 feet the average is 2.1 or something like that. So the thought is you should be making all putts within 20 feet in 2 putts or less.

      If you miss GIR chances are you are with 50 yards of a hole and you will need to chip and 1 putt to save par. My making a mistake here your shot at par goes away completely. GIR gives you a better chance of making par, but being able to scramble for par is also just as important if not more important. The tour average for GIR is 75%, so that remaining 25% can make or break you.

      • Peter Sanders

        Jun 5, 2016 at 12:31 pm

        Jim,
        Thanks for your supporting comments. I have to call you to task on the Tour stats that you mention:

        1. “Tour average w/i 20 ft. is 2 putts.” – The 2.0 distance on Tour is 34 ft. That means that they average 2 putts from that point and will do better inside that.

        2. “The Tour avg. for GIR is 75%” The winners on Tour average only 70% GIR’s. The Tour average in 2015 for GIR’s was 64.5%.

        • Jim

          Jun 6, 2016 at 7:00 am

          Yup, I don’t have the latest stats. Your stats seem to help more though now. I’m sure the probability of making 2 putts within 20 feet is higher the lower the handicap. My whole thing was the 20 feet is a must for 2 putts. If you can’t 2 putt within 20 feet, your got work to do.

          The 64.5% GIR is a stronger argument for your 50 yard stat. That means 35.5% of shots will be scrambles for par, and missing those will have a huge impact on your score. I’m sure there is also a sliding scale for handicap. The higher the handicap the lower the GIR% is, but even at that, that means the higher the scramble% is. Meaning you have an even greater importance on being able to scramble within 50 yards.

          • Peter Sanders

            Jun 6, 2016 at 9:29 am

            You are correct about the sliding scale for GIR’s. It is the most important of all of the “traditional” stats. There is a direct correlation between GIR’s and score – always. A GIR means two good things:
            1. Your game has been efficient enough to get there in regulation.
            2. It is always a birdie opportunity of some length.

            The 90 shooter averages less than 5 GIR’s.

            • Double Mocha Man

              Jun 6, 2016 at 11:27 am

              I’ve come up with a stat I call BGIR. (Bigger Green in Regulation”) If I’m a few yards off the green with an easy chip or on the fringe where I can easily putt I count these as BGIR’s… they almost always still result in pars, the occasional birdie. It’s when I miss the green by 10 -15 yards that I am in trouble. My BGIR rate is about 72%. It’s that 28% that kills my score.

              • Double Mocha Man

                Jun 6, 2016 at 11:30 am

                Oh, and the occasional smothered duck hook…

    • Peter Sanders

      Jun 5, 2016 at 12:25 pm

      Adam,
      Q 1: Yes, it is fairly normal for the 80 and 90 shooter to 3-Putt from outside 20 feet. The average 2.00 putt distance for the 90 shooter is inside 20 feet. While 3-Putts outside are not good, I do not consider them to be Errors.

      Q 2: Good Q! I had a lot of help and advice from notable instructors like Chuck Cook, Jack Lumpkin and Hank Johnson early on. We all finally agreed that within 50 yards was clearly short game for every handicap level – 75 yard can be a full approach shot for many.

Top 5 wedges of all time

Published

on

Wedges. They are the “trusted old friends” in our golf bags. They inspire confidence inside of 100 yards and help us get back on track when we hit a wayward approach.

There was a time not too long ago when a bunker was considered a true hazard, but over the last 80 years, as agronomy has evolved on the same trajectory as club an ball technology, wedges have changed a great deal along the way—from the first modern prototype wedge built by Gene Sarazen to clubs featuring various plating and coatings to increase spin and performance. There are a lot of wedge designs that have stood the test of time; their sole grinds, profiles from address, and performance bring back memories of great hole outs and recovery shots.

With so many variations of wedges in the history of golf (and so much parity), this is my top five list (in no particular order) of the most iconic wedges in golf history.

Original Gene Sarazen Wedge

Gene is famous for a lot of things: the career grand slam, the longest endorsement deal in professional sports history (75 years as a Wilson ambassador), the “shot heard around the world”, and as mentioned earlier—the creation of the modern sand wedge. Although not credited with the invention of the original  “sand wedge” he 100 percent created the modern wedge with a steel shaft and higher bounce. A creation that developed from soldering mass to the sole and flange of what would be our modern-day pitching wedge. Born from the idea of a plane wing, thanks to a trip taken with Howard Hughes, we can all thank Mr. Sarazen for the help with the short shots around the green.

Wilson R90

The next evolution of the original Sarazen Design, the Wilson R90 was the very first mass-marketed sand wedge. Its design characteristics can still be seen in the profile of some modern wedges. Although many might not be as familiar with the R90, you would almost certainly recognize the shape, since it was very often copied by other manufacturers, in their wedge lines.

The R90 features a very rounded profile, high amount of offset, and a great deal of bounce in the middle of the sole, with very little camber. Although not as versatile as modern wedges because of the reduced curve from heel to toe, the R90 is still a force to be reckoned with in the sand.

Cleveland 588

You know a name and design are classic when a company chooses to use the original notation more than 30 years after its initial release. The 588 was introduced as Cleveland’s fifth wedge design and came to market in 1988—which is how it got its name. Wedges were never the same after.

The brainchild of Roger Cleveland, the 588 was made from 8620 carbon steel—which patinad over time. Not unlike the Wilson before it, the 588 had a very traditional rounded shape with a higher toe and round leading edge. The other part of the design that created such versatility was the V-Sole (No, not the same as the Current Srixon), that offers a lot more heel relief to lower the leading edge as the face was opened up—this was the birth of the modern wedge grind.

Titleist Vokey Spin Milled

The wedge that launched the Vokey brand into the stratosphere. Spin-milled faces changed the way golfers look at face technology in their scoring clubs. From a humble club builder to a wedge guru, Bob Vokey has been around golf and the short game for a long time. The crazy thing about the Bob Vokey story is that it all started with one question: “who wants to lead the wedge team?” That was all it took to get him from shaping Titleist woods to working with the world’s best players to create high-performance short game tools.

Honorable mentions for design goes to the first 200 and 400 series wedge, which caught golfers’ eyes with their teardrop shape—much like the Cleveland 588 before it.

Ping Eye 2 Plus

What can you say? The unique wedge design that other OEMs continue to draw inspiration from it 30 years after its original conception. The Eye 2+ wedge was spawned from what is undoubtedly the most popular iron design of all time, which went through many iterations during its 10 years on the market—a lifecycle that is completely unheard of in today’s world of modern equipment.

A pre-worn sole, huge amount of heel and toe radius, and a face that screams “you can’t miss,” the true beauty comes from the way the hosel transitions into the head, which makes the club one of the most versatile of all time.

Check out my video below for more on why this wedge was so great.

Honorable mention: The Alien wedge

To this day, the Alien wedge is the number-one-selling single golf club of all time! Although I’m sure there aren’t a lot of people willing to admit to owning one, it did help a lot of golfer by simplifying the short game, especially bunker shots.

Its huge profile looked unorthodox, but by golly did it ever work! Designed to be played straight face and essentially slammed into the sand to help elevate the ball, the club did what it set out to do: get you out of the sand on the first try. You could say that it was inspired by the original Hogan “Sure-Out,” but along the way it has also inspired others to take up the baton in helping the regular high-handicap golfer get out of the sand—I’m looking at you XE1.

That’s my list, WRXers. What would you add? Let me know in the comments!

A day at the CP Women’s Open

Published

on

It’s another beautiful summer day in August. Just like any other pro-am at a professional tour event, amateurs are nervously warming up on the driving range and on the putting green next to their pros. As they make their way to the opening tees, they pose for their pictures, hear their names called, and watch their marque player stripe one down the fairway. But instead of walking up 50 yards to the “am tees,” they get to tee it up from where the pros play—because this is different: this is the LPGA Tour!

I’m just going to get right to it, if you haven’t been to an LPGA Tour event you NEED to GO! I’ve been to a lot of golf events as both a spectator and as media member, and I can say an LPGA Tour event is probably the most fun you can have watching professional golf.

The CP Women’s Open is one of the biggest non-majors in women’s golf. 96 of the top 100 players in the world are in the field, and attendance numbers for this stop on the schedule are some of the highest on tour. The 2019 edition it is being held at exclusive Magna Golf Club in Aurora, Ontario, which is about an hour north of downtown Toronto and designed by noted Canadian architect Doug Carrick. The defending Champion is none other than 21-year-old Canadian phenom Brooke Henderson, who won in emotional fashion last year.

From a fan’s perspective, there are some notable differences at an LPGA Tour event, and as a true “golf fan,” not just men’s golf fan, there are some big parts of the experience that I believe everyone can enjoy:

  • Access: It is certainly a refreshing and laidback vibe around the golf course. It’s easy to find great vantage points around the range and practice facility to watch the players go through their routines—a popular watching spot. Smaller infrastructure doesn’t mean a smaller footprint, and there is still a lot to see, plus with few large multi-story grandstands around some of the finishing holes, getting up close to watch shots is easier for everyone.
  • Relatability: This is a big one, and something I think most golfers don’t consider when they choose to watch professional golf. Just like with the men’s game there are obviously outliers when it comes to distance on the LPGA Tour but average distances are more in line with better club players than club players are to PGA Tour Pros. The game is less about power and more about placement. Watching players hit hybrids as accurately as wedges is amazing to watch. Every player from a scratch to a higher handicap can learn a great deal from watching the throwback style of actually hitting fairways and greens vs. modern bomb and gouge.
  • Crowds: (I don’t believe this is just a “Canadian Thing”) It was refreshing to spend an entire day on the course and never hear a “mashed potatoes” or “get in the hole” yelled on the tee of a par 5. The LPGA Tour offers an extremely family-friendly atmosphere, with a lot more young kids, especially young girls out to watch their idols play. This for me is a huge takeaway. So much of professional sports is focused on the men, and with that you often see crowds reflect that. As a father to a young daughter, if she decides to play golf, I love the fact that she can watch people like her play the game at a high level.

There is a lot of talk about the difference between men’s and women’s professional sports, but as far as “the product” goes, I believe that LPGA Tour offers one of the best in professional sports, including value. With a great forecast, a great course, and essentially every top player in the field, this week’s CP Women’s Open is destined to be another great event. If you get the chance to attend this or any LPGA Tour event, I can’t encourage you enough to go!
