Sergio Garcia proved again why he's his own worst enemy on Sunday, when he derailed his rise up the BMW Championship leaderboard with a string of poor shots and questionable decisions on the second-to-last hole of the tournament.
Trailing by two strokes with two holes to play, Garcia laid up on the par-5 17th, airmailed his third shot over the green and then chipped into the water hazard.
It's hard to watch, but here it is:
Garcia would make a triple-bogey 8 on the hole -- a "snowman" in golf parlance -- the lone blemish on an otherwise stellar round of 67.
The costly chip dropped Garcia into a tie for fourth with Rickie Fowler, Jim Furyk and Ryan Palmer at 9 under, four strokes behind the eventual winner Billy Horschel.
"It's what happens when you're not mentally sharp," said Garcia after his round of his decision not to attack the green on 17. "Then, just a mistake after another mistake."
NBC's Johnny Miller offered a different assessment on the air: "That is just a flat choke."
