Nick Watney's 65 matched the low round of the Masters.
Got him an invitation back for next year, too.
The top 16 and ties automatically qualify for next year's Masters, and Watney finished alone in seventh place.
"It's always nice to nail down an invitation," said Watney, who began the day tied for 16th. "I felt like if I played a good round that would take care of itself. Then once I got off to a good start I just kind of wanted to keep it going and kind of ignored all the, tried not to get too lost in the moment. But it's definitely nice to have an invitation back here next year."
Also earning return trips were Lee Westwood; Anthony Kim; K.J. Choi; Hunter Mahan; Ricky Barnes; Ian Poulter; Miguel Angel Jimenez; Jerry Kelly; Ryan Moore; David Toms and Steve Marino. Winner Phil Mickelson, Tiger Woods, Fred Couples and Trevor Immelman were already exempt as past champions.
