Bubba Watson shot a final round 69(-2) to win by two shots at the Genesis Open at Riviera Country Club.
It was the American’s first win since he triumphed here in 2016.
It is his 10th PGA Tour win and his third at this tournament after first winning the in 2014.
Watson – a two-time Masters winner – said after the round that he considered retirement after dropping to 117th in the world.
He said: “The last year and a half, almost two years, has been a struggle, because I want to be at the top.
“I was top 10 in the world for a few years, so not being there you feel like: ‘Is this it? Is this my old man moment where I can’t play golf again?”
If it wasn’t for his wife Angie then we may not have been able to see the enigmatic Watson play the game again.
“I was close to retiring – my wife was not close,” he said.
“My wife basically told me to quit whining and play golf. She’s much tougher than I am. I was focusing on the wrong things – pitiful me and not how beautiful my life was.
“Nobody thought Bubba Watson from Bagdad, Florida would ever get to 10 wins – without lessons, head case, hooking the ball, slicing the ball, can’t putt.”
Watson now heads to Augusta in April looking to add a third green jacket. The signs are good. He won here at Riviera in 2014 before going on to win that year’s Masters.
He will move back into the world’s top 50 for the first time since last summer.
Kevin Na and Tony Finau finished two shots back from Watson in a tie for second.
Dustin Johnson couldn’t reproduce the magic of Saturday’s round and a disappointing 73 left him in a tie for 16th.
Phil Mickelson looked set to produce a stunning comeback win. Five birdies in the first 12 holes moved him right into contention before a couple of late bogeys put an end to his chances.
There will be another strong field for next week’s Honda Classic. Rickie Fowler will head there as defending champion.
