South Korean Kim Si-woo broke through for his first PGA Tour title after winning the Wyndham Championship by five strokes on Sunday.
Kim had never won on Tour, coming close at the Barbasol Championship following a play-off defeat to Aaron Baddeley in July.
But that all changed for the 21-year-old - a star on the Web.com Tour and the second youngest winner in history on the developmental tour after Jason Day - after he closed out the tournament with a final-hole birdie, ahead of former world number one Luke Donald at 21 under.
Kim teed off with a four-stroke lead at Sedgefield Country Club and he extended that by a stroke via a final-round 67, following a delay in play late in the day which lasted almost one and a half hours due to inclement weather in Greensboro, North Carolina.
Donald, who hit a hole-in-one in the opening round, finished in sole possession of the runner-up position after carding a three-under-par 67.
Hideki Matsuyama (67) and Brandt Snedeker (67) closed out the tournament six shots off the pace.
A stroke further back were Brett Stegmaier (64), Johnson Wagner (67), Billy Horschel (68), Graeme McDowell (68) and Rafa Cabrera-Bello (70), who tied for fifth at the Olympic Games in Rio.
The top 10 was rounded out by Kevin Kisner (63), Bud Cauley (67), Kevin Na (70) and Jim Furyk (70).
