Putts Gained Statistical Rankings

Here's an interesting article by the Wall Street Journal discussing a new statistical study set forth by some MIT mathematicians in order to better rank putters on the PGA Tour. WALL STREET JOURNAL ARTICLE

Here's the key premise to the article:
With this baseline established, the model compares the results of each putt a pro takes to the expected putts-to-go average on that particular green by a hypothetical average field. If a player holes a 15- footer whose value is 1.82, he gains .82 strokes on the field. If he needs two putts, he loses .18 strokes on the field. At the end of the round, the model adds up all the pluses and minuses to produce the net putts-gained statistic.

The best putter in 2009 by this measure was Luke Donald, who gained an average of 0.905 strokes on the field by virtue of his putting skill alone. Mr. Stricker, who finished No. 1 in putting average last year largely because of his proficiency with approach shots, ranked a surprising 69th in putts gained per round. (Deeper analysis by MIT showed that Mr. Stricker's ranking was also negatively affected because he happened to play on the "easiest" greens of all 166 players sampled.)
I applaud the PGA Tour for trying to put this together. This is very much along the lines of baseball's 'Sabermetrics' methodology which is widely used today. For instance, Sabermetrics can measure pitchers performances by looking at how they do given strength of competition and the ballpark they pitch in. So, if Pitcher A has a 3.00 ERA at a 'hitters park' and Pitcher B has a 2.80 ERA at a 'pitcher's park', Sabermetrics can go into detail and show who was truly the better pitcher.

So, here are the rankings from 2009 of 'putts gained.'

Let's take a look at this in conjunction with my '2009 Total Ballstriking Stats'

First, let's take a look at the top 10 PUTTS GAINED and see where they ranked in my total ballstriking stats. The ballstriking rankings will be in parentheses:

1. Luke Donald (141)
2. Tiger Woods (13)
3. Ben Curtis (169)
4. Bryce Molder (47)
5. Brad Faxon (184)
6. Jim Furyk (52)
7. Brandt Snedeker (86)
8. Brian Gay (93)
9. Matt Kuchar (97)
10. Aaron Baddeley (179)

Now, let's take a look at the top 10 BALLSTRIKERS and their putts gained rankings:

1. Jason Bohn (174)
2. Heath Slocum (192)
3. David Toms (90)
4. Jay Williamson (222)
5. Robert Allenby (206)
6. Greg Owen (186)
7. Joe Durant (215)
8. John Senden (102)
9. Kenny Perry (56)
10. D.J. Trahan (188)

I'll probably be referring to this in my 'scouting reports' and Major Championship overviews on the forum.

Great post, Rich.

The stat really bears out just how bad the Aussies Scott and Allenby have been putting. Allenby in particular should be killing it if he could putt halfway decently (although he's showing some signs of improvement recently, it still looks very fragile).

I think this stat will become very important in form analysis - what do you think?


PS - Looking forward to hearing further swing updates from you now you're doing the ABS modules.

I asked Geoff Mangum about it over at his forum and he didn't like it. I don't think it was specific enough for him and it really doesn't help him or the amateur. It does help the PGA Pro know if they are good or if they suck, but not why they are good or why they suck.

I'm not as down on it as Mangum is because I think in the end it provides a decent ballpark on how well guys putt. Any of those guys in the top 10 have been regarded as great putters in their career. So it's not a big mystery as to why when looking at their rankings.
