*G Ogilvy won play-off
Ogilvy finished 72 holes on 19 under par alongside youngster Kevin Na and Mark Calcavecchia but went on to take his maiden PGA Tour title.
A final round of 68 lifted Jose Maria Olazabal to a tie for ninth.
Britain's Philip Price was four shots further back but Brian Davis shot a five-over-par 77 to finish in 62nd.
Ogilvy, who had finished second three times on tour, carded a one-under 71 in the final round after two bogeys and no birdies on the back nine.
Calcavecchia got into the play-off with a 69 while Na was tied with Ogilvy for the 54-hole lead and needed a birdie on 18 to join the play-off.
The trio went back to the par-four 18th to start the play-off where Calcavecchia was eliminated after a double-bogey.
Ogilvy had a chance to win with a birdie putt from 28 feet but had to settle for par.
Na, the youngest player on tour, extended the play-off another hole by draining a 27-footer.
After both players drove in the rough on the par-five 10th, Ogilvy punched out 100 yards from the green while Na took a shot at the flag and rolled his ball to the back fringe.
Ogilvy's third shot put him 18 feet away while Na chipped to eight feet.
Ogilvy then calmly sank his birdie putt and Na failed to convert for his second runner-up finish of the season.
