Patrick Reed birdied the second play-off hole to clinch his maiden PGA Tour title at the Wyndham Championship.
Reed and his fellow American Jordan Spieth both finished regulation play at 14-under-par and had matching par fours at the first hole of sudden death, the 18th.
Both had birdie chances when the action moved onto the par-four 10th, but Spieth's effort from 10 feet trickled just wide and Reed stepped up to roll in his from around seven feet.
Reed started the final day in a share of the lead with John Huh and produced a four-under 66 - his only bogey of the day coming at the 16th.
That meant Spieth's 65 - which featured four birdies on the back nine including at the 17th - was good enough for a play-off.
Huh's 68 gave him a share of third alongside Brian Harman (66) on 12 under, while Australian Matt Jones fired the low round of the day, 62, to finish as the first non-American a stroke further back.
Matt Every (67) and Zach Johnson (68) were tied for fifth on 11 under with Jones.
