Japan’s Hideki Matsuyama won the Genesis Invitational after an incredible fightback in the final round.
His nine-under 62 to secure the victory was one stroke shy of the Riviera Country Club course record.
The 2021 Masters champion, 31, started the day six shots behind leader Patrick Cantlay, but finished at 17 under par to win his ninth PGA Tour title.
Cantlay finished fourth, behind Will Zalatoris and Luke List.
The American trio was stunned by Matsuyama, who started the day with three birdies and added six more in the back nine to all but secure his victory.
“I didn’t hit the ball really well, but my chipping and putting worked a lot this week,” Matsuyama said.
“It’s really important for me to keep that momentum going, especially going to Augusta.”
Zalatoris and List both finished at -14 while Cantlay was tied for fourth at -13 with American Xander Schauffele and Canadian Adam Hadwin.
England’s Tommy Fleetwood finished in a five-way tie for 10th after closing with a 67, while world number two Rory McIlroy finished 24th with a final round of 70.
“I think I’m close. I’m not quite where I want to be,” McIlroy told CBS News.
“It’s one of those courses where you know that accuracy is so important and you have to put your ball in the right areas. If you’re slightly behind, your weaknesses are kind of magnified this week.”
The US PGA Tour continues with the Mexican Open on February 22.
