Si Woo Kim shot an 8-under 64, just enough to hold off Patrick Cantlay's final-round charge and wrap up The American Express tournament in La Quinta, Calif., on Sunday.
Kim's third consecutive bogey-free round included eight birdies, occurring four times on consecutive holes, concluding on Nos. 16 and 17 before a closing par on the Stadium Course. It was Kim's third career win on the PGA Tour, and he finished third at last week's Sony Open.
The South Korean held off Cantlay, who fired the best round of the day, 11-under 61, to finish at 22-under. He set the course record by two strokes in the process. He also finished bogey-free on the day, one of five players to do so, with 11 birdies and seven pars, accelerating his pace from Saturday's 65 that kept him in contention.
Kim said he was well aware of how well Cantlay was playing.
"I knew Cantlay played really well. I tried to keep patient and believe in myself. I got the chance on 16 and 17, and that's when I could make it. I feel good about myself," Kim said.
Cantlay, who began the day tied for 13th at 11-under, posted birdies on four of his first six holes, and again on three of his final four. His nine birdies on Saturday had been his career best.
"I knew they still had a bunch of holes left, but really I put myself so behind the 8-ball," Cantlay said, referring to shooting 69 and 71 on Thursday and Friday, respectively. "I played unbelievable this weekend. I did everything I could. Just going to be a shot short."
Australia's Cameron Davis finished alone in third place, his best finish on the PGA Tour, at 20-under thanks to a bogey-free 8-under 64. He was hot at the start, posting six birdies on the front nine.
Tony Finau, who began the day tied atop the leaderboard with Kim and Max Homa, shot 4-under 68. He could not overcome two bogeys in a four-hole span on the back nine and finished along in fourth place at 19-under 269, but was not downbeat about his showing.
"A couple of those guys just went really low today. I had some opportunities, I think, to shoot a number. But man, I'm kind of leaving today pretty encouraged. I played nicely," Finau said.
Homa had a worse fate, ballooning to a 4-over 76 thanks to four bogeys with only two birdies on Sunday. He finished at 11-under 277.
The defending champion, Andrew Landry, fired his second consecutive 2-over 74 to end at 1-under 287.
Tied for fifth at 15-under 273 were Mexico's Abraham Ancer (a final round 66), Michael Thompson (66) and Doug Ghim (69).
