Steve Stricker triumphed at the second extra hole to win the Crowne Plaza Invitational at Colonial after a three-way play-off.
The American came up with a birdie at the crucial moment to pip Steve Marino and Tim Clark, who led by two shots with five holes of his final round to play.
The South African had gone into the fourth round with a two-shot lead and looked set for his first PGA Tour victory. But, after bogeying the 14th, he then dropped a shot at the last for a level-par 70.
That put him level with Stricker and Marino, who both shot 68s, at 17 under.
Clark should still have won at the first extra hole but he missed a short putt and saw his luck take a turn for the worse at the second when his approach hit the flag and rolled away, and he missed his birdie chance to open the door for Stricker.
It is the seventh time Clark has finished as a runner-up on the PGA Tour, and the second time in as many years at the Texas tournament.
Australian Jason Day finished fourth after a final-round 69 while new world number three Paul Casey followed up his BMW PGA Championship triumph with fifth place.
The Englishman birdied his first three holes on the way to a four-under-par 66 - his third of the tournament - and a final score of 15 under.
Woody Austin and Vijay Singh tied for sixth a further shot back while England's Ian Poulter shot a 68 to finish on 12 under.
Another Englishman, Luke Donald, had to settle for a level-par 70 and a tie of 13th place on 10 under while Justin Rose and Brian Davis both finished on six under.
