He really only hit one 'choke shot'.
The first one would have been safe had it landed 1 or 2 feet further up the hill. He would have made a 3 and won the tournament.
The shot into the bunker wasn't great but its only natural that he overshot given the previous two shots (and he made a pretty incredible up and down out of that bunker).
That really only leaves him with one choke shot. That second approach where he barely made the water. That was above the shoulders, pure and simple. A total choke where the moment got inside his head.
One terrible shot under extreme pressure. One. Out of of 286 that he hit over 4 days, the vast vast majority of which were perfect.
And that's the only shot he'll be remembered for.
