(Reuters) - Kevin Kisner, a runner-up four times this year, secured his first PGA Tour win with a flourish, firing his second successive 64 for a six-shot victory in the RSM Classic in coastal Georgia on Sunday.
Kisner, 31, began the final round with a three-shot lead and turned it into a romp with five birdies on the front side to make the turn in 30.
He finished with a six-under round at the Seaside course at Sea Island for a tournament record 22-under-par 260 total.
American Kevin Chappell shot 67 to take second place on 16-under 266, one stroke better than Northern Irishman Graeme McDowell, who also returned a 67 on St Simons Island.
