How to Catch a Tiger: Understanding Putting Performance on the PGA Tour

Douglas Fearing, Jason Acimovic, Stephen C. Graves
January 18, 2010

Abstract:
Existing performance metrics utilized by the PGA TOUR have biases towards specific styles of play, which make relative player comparisons challenging. Our goal is to evaluate golfers in a way that eliminates these biases and to better understand how the best players maintain their advantage. Through a working agreement with the PGA TOUR, we have obtained access to proprietary “ShotLink” data that pinpoints the location of every shot taken on the PGA TOUR. Using these data, we develop distance-based models for two components of putting performance: the probability of making the putt and the remaining distance to the pin conditioned on missing. The first is modeled through a logistic regression, while the second is modeled through a gamma regression. Both of these models fit the data well and provide interesting insights into the game. Additionally, by describing the act of putting using a simple Markov chain, we are able to combines these two models to characterize the putts-to-go for the field from any distance on the green for the PGA TOUR. The results of this Markov model match both the empirical expectation and variance of putts-to-go. We use our models to evaluate putting performance in terms of the strokes or putts gained per round relative to the field. Using this metric, we can determine what portion of a player’s overall performance is due to advantage (or loss) gained through putting, and conversely what portion of the player’s performance is derived off the green. We demonstrate with examples how our metric eliminates significant biases that exist in the PGA TOUR’s Putting Average statistic. Last, extending the concept of putts gained to evaluate player-specific performance, we show how our models can be used to quickly

A Stat Is Born: Golf's New Way to Measure Putting

Steve Stricker falls from No. 1; Brad Faxon climbs the charts; Tiger still great; who's the best?



Researchers at the Massachusetts Institute of Technology, working with the PGA Tour, have come up with a way to solve one of golf's biggest conundrums: how to determine who are the truly great putters in the game.

Putting, as any golfer with more than 30 minutes experience on an actual course will tell you, is the key to scoring. The old saw "drive for show, putt for dough" is a bedrock truth among professionals. But until now there hasn't been a reliable statistical method of measuring putting skill among the world's best golfers.

The main problem is that too many external variables come into play. The most commonly used putting statistic, "putting average, " measures the number of putts that a player takes per round when his ball lands on the green in regulation—that is, in par less two strokes (for example, in two strokes on a par-four hole). Not only does this approach exclude about 30% of putts attempted on the PGA Tour (those made on greens not reached in regulation), but it also rewards the accuracy of shots into the green as much as it does putting skill.

Distance = Club Head Speed + Square Impact

Most golfers are influenced by certain myths in playing golf. One such myth would be to slow down their swing. Thinking like that is exactly why golfers can not hit the ball as far as they want. Let's do some reasoning with club head speed. Take any club you want with everything being the same. Same impact on the face, same loft at impact, the following is going to be true. Swing the club slower and the ball will not go longer, it will go shorter.

There is only one way to increase the distance you hit your metal woods or irons. A combination of increased club head speed and how solid you hit the ball on the center of percussion, a.k.a. "sweet spot".

If each golfer focused on learning to hit the ball solid and in the "sweet spot" they would be amazed at how much distance would be picked up. Now, most golfers are influenced by certain myths in playing golf.

The average golfer’s problem is not so much a lack of ability as it is a lack of knowing what he should do.” Ben Hogan

What is the problem? The problem is simple, poor impact. Golfers practice the wrong thing and get good at doing it wrong. The contact with the golf ball and golf club face at moment of impact is not consistent. Why is this important? Impact controls trajectory, distance, and direction of each shot. These three things are affected each time the club face and ball collide. A golfer’s only feedback is the flight of the ball. Every fifth or sixth shot most golfers make good contact by accident. As a result, the golfer does not know what they have done differently to make the good contact happen.

격심 [Center of Percussion, 擊心]

물체가 외부의 힘을 받아 움직일 때 회전 반작용에 의한 영향을 가장 적게 받는 힘의 작용점을 말한다. 야구 방망이의 이 부분에 공이 날아와 맞을 경우 충격력이 최소가 되므로 가장 멀리 공이 되튀어나갈 수 있다.

타격중심이라고도 한다. 어떤 물체가 외부로부터 힘을 받아 움직일 경우, 어떤 점을 중심으로 회전을 하게 되면 그 물체의 회전축에서 회전 반작용의 영향을 거의 받지 않는 지점이 있다. 즉, 외부의 힘을 가장 적게 받는 작용점이 있는데, 이 작용점을 무게중심과 구분해 격심이라고 한다.

예를 들어 야구에서 타자가 배트를 휘둘러 공을 때리게 되면, 공을 맞히는 순간 타자에게는 충격력이 전해진다. 이때 공을 때리는 배트의 위치에 따라 타자가 받는 충격력은 달라진다. 공이 타자의 손에서 가깝게 맞으면 맞을수록 충격력은 커지고, 반대로 공이 배트의 격심에 정확히 맞으면 맞을수록 충격력은 줄어든다.

다시 말해 타자가 배트를 휘둘러 공이 가장 멀리 날아갈 수 있는 지점이 있는데, 이 지점이 격심이다. 따라서 격심에서 멀어질수록 회전 반작용에 의한 영향을 강하게 받아 타자가 받는 충격력은 커진다. 골프 헤드에도 스위트 존(sweet zone)이라는 표시가 있는데, 이 스위트 존이 무게중심과는 다른 헤드의 격심이다. 이 지점에 맞아야 공이 가장 멀리 날아간다.

Putt Probabilities

By IAN AYRES

Like many others, I was incredibly jazzed by Tiger’s victory on Monday.

But I was frustrated that the commentators routinely failed to mention the putting distance to the hole. It would be nice to know, “It looks like Rocco has a 25-foot putt.” But I, for one, would like commentators to go further and routinely give us information about the probable outcome of the next stroke. If the golfer is putting, I want to know the probability that the put will go in.

Analogous information is an old hat in basketball. When Kevin Garnett goes to the free-throw line, we are told what his FT percentage has been this season and in the playoffs (and in this very game).

Putting is not as standardized as shooting a free throw. But it would be useful to know that pros generally only make 60 percent of five puts. At least that’s what’s shown in this article (based on pre 1995 data):

Woods' performance since the British Open

By Mike Vitti
PGATOUR.com ShotLink Analyst

Tiger Woods equaled his career-best PGA TOUR victory streak over the weekend, winning his sixth consecutive event-the World Golf Championships-American Express Championship- by eight shots. It is obvious that Woods has been playing at a very high level over his last six starts, but the question is: just how good has he been and what has he improved upon to get on such a roll?

• Woods' putting average of 1.713 during the win streak is slightly better than the 1.718 average of current PGA TOUR leader Daniel Chopra.

• Overall, Woods is saving about one stroke per round on the greens; however, the difference in putts per round during the first two rounds is much more significant. In round one and round two before the streak, Woods was averaging 29.75 and 30.25 putts per round respectively. During the streak, he has averaged 27.83 and 27.33 putts per round in the same two rounds.

• Putts measuring between 10 and 25 feet in length are where Woods has improved his performance on the greens. He has improved his percentage of made putts by at least 17 points on putts measuring between 10-15 feet and those measuring 15-20 feet. On putts between 20 and 25 feet, Woods has gone from making 6.3 percent of his attempts to an average of 28.6 percent.

• The improvement in putting during the streak has Woods making an additional 15 feet of putts per round, with his average during the streak exceeding the current TOUR leader, Richard S. Johnson, by about 5 feet.
