OK, Know-it-all: What IS Yang's Problem?

I hope you read my last entry. In it I pointed out what I believed to be Johnny Miller's mistaken assessment as to why Y.A. Yang does not measure up to the top level on the PGA Tour. I took exception to Johnny's blaming Yang's post-PGA invisibility on missed fairways. I pointed out that while Y.A. does hit the fairway just over 60% (60.56) of the time, Tiger hits only 64%. I left out a more dramatic example of just how irrelevant the "Fairways" stat is - Phil Mickelson, the #2 player in the world, hit only 52% of his fairways in 2009.

But I could not call out Johnny Miller without offering a better explanation for why we aren't hearing more about Yang. The real answer to the question was not easy to find because, unlike Tiger, whose data I retrieve and analyze after every event, I do not have Y.A.'s ShotByShot.com data. As a result, I had to dive into the massive statistical storehouse of the Tour's ShotLink database. If one is fortunate enough to have access to this robust research tool, one can retrieve more bits of data than one can possibly process, and the pieces of the puzzle are in there somewhere....

I started with the old faithful long game measure - Greens-Hit-in-Regulation - the most pertinent of all of the traditional stats, especially at the Tour level. This stat consistently maintains the strongest direct correlation to scoring and winning of all the stats on Tour. Why? Because it signals a lack of errors in the long game and also corresponds to birdie opportunities. Y.A. hit 66% of his greens, just behind Tiger at 68%, and Tiger is ranked 12th on Tour. This only confirmed that Y.A.'s long game was not his major issue.

Next, I looked at the Tour's Scrambling stat. This is the percent of "saves" (par or better) when the player has failed to hit the green in regulation. Not perfect, but a fairly good overall short game barometer. Y.A. saved 58% of these short game opportunities, ranking 91st on Tour - barely better than the Tour average (57.5%). Tiger ranks #1 on Tour at 68% - this is a significant difference.

Finally, I looked at what I believe to be the Tour's best putting stat yet: Total Putting. This stat considers the weighted average (based upon number of opportunities) of six putting stats. The first five are the % 1-putt in each of the following critical ranges: (3-5 feet, 5-10 feet, 10-15 feet, 15-20 feet, 20-25 feet). The sixth is 3-putt avoidance. This is a simple percentage of holes on which a player has 3 or more putts. Again, not perfect, but by far the most representative of overall putting skill that I have seen from the Tour. Y.A. Yang's PGA Tour ranking is 113. This is worse than the PGA Tour average in these categories. By contrast, Tiger, whose putting never looks great based upon the old and useless Putts per GIR, is ranked #8 in this stat.

Bottom line, Johnny - and I'd love the opportunity to discuss this with you - I believe that Y.A Yang has not been as visible among the winners on Tour this year because his short game and putting just don't measure up. Not only does "Average" NOT win on the PGA Tour, these players are rarely ever seen on TV. What I view to be meaningful short game and putting indicators for Y.A. Yang (approximately 50% of the game) are at best average.
