Matt Kuchar overcame an early stumble to win a second PGA Tour title of the season at the Sony Open in Hawaii.
The American entered the final round with a two-shot lead, but three bogeys in his first five holes meant he trailed playing partner Andrew Putnam by a shot at the turn.
The duo could not be separated with five holes to play but Kuchar birdied three of his last four to sign for 66, move to 22 under and win by four shots.
Soon after setting out on Sunday Kuchar bogeyed the second and, while he claimed the shot straight back on the next, two more bogeys on the fourth and fifth allowed Putnam to sneak ahead courtesy of a gain on the third.
Both men birdied the ninth but Kuchar picked up further shots on the 10th and 12th before a Putnam birdie on the 13th looked to set up a tense finish.
Putnam bogeyed the next after finding the sand and Kuchar kept his cool to pull away, the four-time Ryder Cup player birdieing the 15th, 16th and last for an eventually comfortable victory.
Australian Marc Leishman, Americans Hudson Swafford and Chez Reavie, and Canadian Corey Conners finished in a share of third at 17 under.
Ian Poulter carded a closing 68 to finish in a tie for 33rd at eight under, while Scot Russel Knox ended in joint 43rd on seven under.
