Regarding aiming at the middle of the green, this is from the SI Golf Masters Preview dated April 12, 2012 page 36:
Donald,only a month away from taking over the top spot in the World Ranking, arrives at the 12th hole only two strokes off the lead but dumps his tee shot into Rae's Creek, leading to a double bogey.
Van Pelt: When he pulled nine iron, I remember thinking, He better hit it good. Seemed like he did, but the air does funny things down there.
Donald: I was aiming at the middle of the bunker and trying to hit a little hold back to the flag. I pushed it eight or nine yards. It was very deflating.
Would his ball have been wet if he'd pulled it 8 or 9 yards?
