Dublin, USA: American Bryson DeChambeau captured the biggest win of his short professional career with a play-off victory in the Memorial on Sunday.
DeChambeau, 24, birdied the second hole of a sudden-death playoff as South Korean An Byeong-hun put his second shot into the crowd then chipped short of the hole.
American Kyle Stanley was eliminated with a bogey at the first extra hole as DeChambeau and An both parred.
All three players ended regulation tied at 15-under par 273.
Both DeChambeau and Stanley had the chance to win in regulation only to walk off with 72nd hole bogeys.
Tiger Woods' much-anticipated final round push failed to materialize as the 14-time major champion carded an even par 72 for a nine-under total.
