Louis Oosthuizen was the leader heading into the final round of play, but he ended up shooting his worst round of the tournament by shooting a 3-over par for a score of 75 to finish third.
Oosthuizen's two-stroke lead evaporated quickly as he had a tough time on the front nine. He shot six-over through 10 holes before hitting three birdies over the final stretch to save face at 3-over on the day and 14-under for the tournament.
The winner of the tournament was Hunter Mahan who held onto a one-stroke lead over Carl Pettersson through the final four holes to hang on for the win Sunday.
Former Houston Cougar Fred Couples shot a two-over 74 on Sunday to finish the tournament at three-under and tied for 47th. While Houston native Jeff Maggert shot a two-over 74 and was six-under for the tournament and finished in a tie for 29th.
