Luke Donald will need at least a top-two finish in the final event of the season to take the US PGA Tour money list after Ben Crane claimed his fourth victory by edging Webb Simpson on the second play-off hole at the McGladrey Classic in Georgia.
The 35 year old Crane from Portland stormed up the leaderboard with a seven under par final round of 63 at Sea Island.
Simpson earned a play-off by joining his fellow American on 15 under with a blemish-free 66, but missed a three foot putt for par on the second play-off hole - the 17th.
Two Major winners from South Africa rounded off the top five, 2010 Open Champion Louis Oosthuizen 13 under after a 66 and 2008 Masters Tournament winner Trevor Immelman a shot further back following a 69.
Two-time Major winner Angel Cabrera of Argentina finished ten under and tied for sixth after a 67 along with American trio Scott McCarron (68), Kevin Streelman (68), Jeff Overton (69) and Australia's Nick O'Hern (69).
Rookie Michael Thompson had looked on course for his maiden US PGA Tour triumph when he opened up a three-shot lead with three birdies over his first six holes.
The 26 year old from Tucson birdied three straight holes from the fourth and was 16 under through seven, but that was as good as it got as two bogeys on the back nine led to a third-place finish on 14 under.
Billy Horschel, who was just one shot behind overnight leader Thompson at the start of play, opened well with birdies on one and three but endured a nightmare round thereafter.
A triple-bogey seven on the par four fifth and a double bogey on 18 - along with further dropped shots on four, seven and 15 - saw him slip to joint 20th after signing for a five-over-par 75.
Simpson now leads Donald by over $300,000 in the money list race ahead of the final event at Disneyland.
