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.
