Hometown hero Max Homa survived a play-off against countryman Tony Finau to claim the Genesis Invitational.
Los Angeles native Homa clinched his second PGA Tour title after signing for par on the second play-off hole as Finau could only bogey on Sunday.
A play-off was needed after American pair Homa (70) and Finau (70) finished 12 under through 72 holes at Riviera Country Club in California, where overnight leader Sam Burns (69) ended the tournament a stroke adrift.
Homa – who was born in nearby Burbank – still managed to reign supreme, despite a brutal lip-out on the 72nd hole, which would have sealed victory but it sent the event into a play-off instead.
"Been watching this tournament my whole life, it's why I fell in love with golf – wow, didn't think it'd be like this [choking up]," Homa said after winning for the first time since 2019.
"Tiger [Woods] another reason I'm into golf. Had good feelings this week. Been playing great. City of champions, you know – [MLB World Series champions] Dodgers, [NBA champions] Lakers and me now, so it's a weird feeling."
Cameron Smith (67) finished three shots off the pace and outright fourth, two strokes ahead of Spanish star Jon Rahm (66), Viktor Hovland (67) and Matthew Fitzpatrick (71).
World number one Dustin Johnson's title charge faded following a one-over-par 62, which left the American tied for eighth and six shots behind the leaders.
Jordan Spieth (71) – still searching for his first victory since 2017 – closed out the Genesis Invitational tied for 15th, alongside the likes of Xander Schauffele (69) and Patrick Cantlay (72).
Four-time major winner Brooks Koepka (69) and defending champion Adam Scott (66) responded after forgettable third rounds to finish tied for 38th at even par.
