Australian Adam Scott won the Genesis Invitational as world number one Rory McIlroy fell three shots off the pace.
The Northern Irish stood on a draw for the lead on the way to the final round in Riviera, but a two-over 73 saw him finish at eight under par.
Scott played a one – under par 70 to win with two hits from South Korean Sung-hoon Kang and Americans Matt Kuchar and Scott Brown.
Tiger Woods finished 22 shots back, the last of those who made the cut.
"It's a very special win this week," said former number one Scott, 39. "They don't come easy for me these days, so I'm going to enjoy this one.
" It's a great way to start [2020]. This must be my year. I can't afford to let the next 10 years slip away. I have to let it happen now. "
The victory marked Scott & # 39; s first PGA Tour title since 2016, but he had to overcome a double bogey on the par-four fifth, the same hole where McIlroy hit a triple bogey.
He followed that with three birdies, all but sealing the win with a 10 foot on the penultimate hole, before he parried the last to end up at 11.
But McIlroy never recovered from his slip-up, bogeying two more holes to finish fifth.
"Absolutely the most difficult day of the week," said the 30-year-old world number one.
"The wind rose , hole locations were a bit tricky places, the job became stronger again. Everyone found it hard there. "
