What makes a great putter?

Brandt Snedeker ranked #1 in Strokes Gained Putting for the 2012 PGA Tour year.  Quite an accomplishment to be considered the best of the best.  I decided to see if I could find the key to his putting prowess - was there something that clearly separated Brandt from the rest?  My conclusion:  Two things stand out.
     1.  Consistency
     2.  Distance control

Consistency
In 18 events covered by ShotLink, Brandt recorded a negative Strokes Gained total in only five (28%).  While negative, these five poor putting events were not horrible.  The average of the five was only -.325 (only giving up .325 shots per round to the field) and his worst was only -.64.  

Brandt's other 13 events were positive SG numbers and for the year Brandt averaged .860 strokes gained on the field.  This profile is the picture of putting consistency.

But what exactly does he do to achieve this high level of consistent performance?  The answer does not exactly leap out of the Tour stats.  Speaking of the ..., there are NINE putting stat categories and 110 individual putting stats.  Each is expressed in a number or percentage with a ranking for perspective.  Further, there is a high degree of compaction which causes the rankings to sometimes be misleading.  That said, rankings in the TOP-20 on Tour are good in ANY stat.  The Tour average tends to be around 75.

Brandt's ranking for the year in a few stats stood out and lead me to my conclusion:
  • 1 Putts 10-15 feet - rank 4 (this range consistently shows up in the Winners on Tour)
  • 1-Putts > 25 feet - rank 8
  • Putts made over 10 feet - rank 3
  • Putts made over 20 feet - rank 4  
I believe that Brandt's high level of success in the four stats mentioned above comes from a great confidence in his distance control and the relative absence of fear about the length of the next putt.

Distance control
In 2000 and 2001, when Tiger was the dominant player on tour, I did a study of his distance control as it related to the other top players at the time.  I found that they all tended to average 7% of their start distance (40 foot start ==> inside 3 feet = 7%).  I also found that Tiger set himself apart by getting a higher percentage of his long distance lag putts to or past the hole.

ShotLink makes this exercise quite a bit easier and precise.  A study of Brand Snedeker's 2012 putts of 25 feet and greater revealed a similar result:
  • His overall average lag distance - 6.5%
  • 2-Putts - 5.8%
  • 3-Putts - 14.2%
In both instances above (2 and 3 Putts), Brandt got 63% of these long putts to or past the hole.  I can't help but think of the annoying refrain:  Never up, never in!  Obviously, Brandt has taken it to heart.

Finally, we amateurs should take heed and work on distance control.  I like to focus on 10% of the start distance as my goal and highly recommend it.  First, we don't do this for a living and second, the math is much easier.

Muirfield brings out the worst in most - not Matt Kuchar

I have said for years that the frequency and severity of our mistakes in golf have a far greater influence on our score and handicap level than do our good shots.  Jack's event this weekend proved to be a great example of my point.  The table below displays the errors (mistakes) made by Matt Kuchar in his four rounds on Muirfield Village as compared to the average of the field.  For perspective, I added the average number of errors made by the PGA Tour in 2012 for an equivalent four rounds.

Muirfield Village is, without question, one of the most difficult courses visited by the Tour.  It is ranked the 3rd most difficult this year, based upon score over par, just behind PGA National - Champion (#2) and Augusta National (#1).  While I have yet to be invited to play Muirfield, I did walk (actually run) the course some years ago to record Shot By Shot data for Jack and his three pro am partners.  Not quite as much fun as playing but I did not lose a single ball.  
What did I learn?
  • Playing is more difficult than walking.  The three amateurs, not bad golfers, picked up almost as often as they finished holes.
  • Muirfield has lots of water that comes into play around the greens.  (Note the approach shot penalties are more than 2x the 2012 Tour average.)
  • The greens and green complexes are very severe and present difficult short game shots. 
 In my study of the event this week, I was surprised to see that aside from the difficulty of the approach shots to the greens, it was the greens and their surroundings, especially the bunkers, that presented the greatest relative difficulty.  (Note the average number of short game errors were more than 50% higher than the 2012 Tour averages.) The Muirfield field made an error from the greenside sand 19.5% of the time - one in every five attempts.  This compares to 12%, or one in every nine attempts in all of 2012.

Matt Kuchar obviously had his sand game ready for Muirfield's test.  In seven attempts, his average putting distance was 6.7 feet (1.3 ft. closer than the field).  And he saved all seven (100% vs. 49% for the field), obviously with ZERO errors.  Well done, Matt!

How do your errors match up?

How Important are Fairways?

One of my college coaches asked my help to provide some perspective for his players - I love when my clients do that - it's a compliment!

Thanks to my genius programmer, I was able to run a query on the last two years of PGA Tour ShotLink data - 28,272 rounds to be exact - a pretty solid sample.  I looked to see how players score from the fairway vs. rough as well as their relative accuracy from various distances from each.  To be clear, the "rough" locations that I reviewed did not include the intermediate rough, fairway bunkers or any of the many "Other" results.

Score
The cost or scoring difference between hitting the fairway vs. rough is:  .315 strokes
  • Results from the fairway = -.156 (under par)
  • Results from the rough = +.159 (over par)
This means that a golfer who misses half the fairways (7) in a given round loses over 2 shots to par - not counting any Penalty or No shot results driving results that we consider to be errors.

Accuracy
The affect on accuracy is even more dramatic than that on score.  Bottom line, in order to achieve the same accuracy from the rough as the tour enjoys from the fairway at 151 to 175 yards, the players must move as much as 75 yards closer to the target.    

Accuracy from 151 to 175 yards:  
  • Hit Green from Fairway: 71%; Hit Green from Rough: 49%
  • Average Proximity to Hole from Fairway: 28 feet; from Rough: 45 feet
To attain the same the fairway accuracy cited above from the rough, we need to get to the 76 to 100 yard range:
  • Hit Green from Rough: 71%
  • Average Proximity to Hole: 27 feet
Mid point to mid point of these ranges is 75 yards.

One might ask, how does this relate to amateur golfers.  I do not have that data, but my slightly educated guess is NOT SO MUCH.  Why?  Because amateurs do not have anywhere near the accuracy from any position and certainly not from the greater distances.  Thus, it can only fall off so much when faced with shots from the rough.

iPhone App Now Available!


Finally, the App was approved by Apple yesterday morning 5/3/13 and is available as a FREE download from the App Store.  Follow this link:  Download App
Some of the features that I believe make it appealing:
  • Large buttons and numeric keypad makes data entry easy, especially while walking.  I am able to use it on the course WITHOUT my reading glasses.
  • No data connection is required while entering data - works perfectly in "offline" mode.
  • We added Front nine and Back nine review screens to help ensure data accuracy.
  • Missing data is highlighted, with easy navigation to fix them.
  • "Jump to Hole" feature makes navigation simple.
  • Bonus stat summary, such as Driving - Fairways and Errors as well as Short game Saves vs. Errors.  Instant feedback on your round.
  • Courses - Choose from your entire course list, or add a new course on the fly.
It has been a long time coming but I am excited to finally have a product of which I am very proud.  I used it every round during my recent 6-round trip (Field tests).  It was quick and easy - not at all a distraction.  Best of all, when I finished my round I had checked and entered it by the time I had changed my shoes.

I will be very interest in your feedback.

What's so hard about Harbour Town?

I spent much of this weekend camped out in front of my TV multi-tasking - watching the golf (RBC Heritage Classic), while happily collecting data on my players.  It is a special event because it is a special course.  Short by today's standards at 7,101 yards (Par 71), and tight by any standards.  The greens are the smallest on tour and well protected by the thin fairways, towering pine trees, water and SAND.

Accordingly, it plays like a mini-major and tends to bring the very best players to the top.  Tom Watson and Hale Irwin are multiple winners and Davis Love, III has won FIVE times.  The King won the first in 1969 taking home $20,000.  I found it interesting that only 44 years later Graeme McDowell multiplied Arnie's cash by just over 50 times to earn $1,044,000.  My Dad said I should focus on golf NOT football - what did he know?

While the telecast was focused on the leaders, I noticed some uncharacteristic short game errors by some players not quite on camera.  When the event was over, I looked closer and noticed that the frequency of errors from the sand at Harbour Town was unusually high.  I compared the  Tour average YTD, just prior to Harbour Town, to the  average for the field in this event.  The errors from the sand were UP by 55%!  The chart above displays the percentage of Sand shots hit to within 8 feet (a good shot by ShotByShot.com standards) as well as the % Errors (shots that miss the green).  Note, the Harbour Town field would no doubt be proud to fall in the 6 to 9 handicap group based upon the frequency of their faux pas in the sand.   

Why so many mistakes?  My somewhat educated guess is that it was due to the small greens and the severe, collection areas adjacent to most of the greens.  First, given the small greens, the normal miss in the sand tends to be further into the sand - leaving more sand to cover and less green.  Second, the poor (or safe) sand shot that would come to rest on a larger green tends to run off into the collection areas. 

One might say:  "It was the wind on Sunday!"  My thought exactly, so I compared the first 3 rounds to the wind-blown 4th - NOT so.  In fact, the sand errors in the 4th round dropped slightly to only 15% (3 to 5 Handicap).

So, whatever your handicap, when you plan to tee it up at Harbour Town, bring your A sand game.
