SAN DIEGO — Bubba Watson tempered his celebration when he rolled in a 12-foot birdie on the final hole Sunday at Torrey Pines, knowing Phil Mickelson could still eagle the par-5 closing hole to catch him.
It played out just as Watson imagined, right down to Mickelson's caddie tending the pin on the eagle attempt.
There was just one twist — Mickelson wasn't near the green. In a surprising decision, Mickelson laid up on the 18th hole and settled for birdie when his 72-yard lob wedge stopped 4 feet from the hole.
Watson won the Farmers Insurance Open with clutch putts on the final two holes for 5-under 67 and 272 total. He was in the scoring trailer at the end, oblivious to how the last hole played out.
"I don't know how close he hit it. I don't know what he made on the hole," Watson, 32, said. "I just know that I won, because that's all I was worried about. If he makes it, I'm getting ready for a playoff. So I'm trying not to get too emotional. I realize it's Phil Mickelson. He can make any shot he wants to."
Watson finished at 16-under 272 for his second tour victory.
Tiger Woods ended his five-tournament winning streak at Torrey Pines with 75, his 1-under 287 total tied for 44th. He had never finished outside the top 10 at Torrey Pines.
"I have some work to do," he said. "There's no doubt about that."
From 228 yards on No. 18, Mickelson figured his best chance at eagle was a 64-degree wedge from the fairway. He tapped in for birdie and 69.
"Bubba played some terrific golf," Mickelson said. "I did what I thought would be enough, and it just wasn't."
Bill Haas, who shared the lead with Mickelson going into the final round, bogeyed the first hole and never caught up, tying for ninth after carding 75.

EUROPEAN: Paul Casey sank a 5-foot par at the last hole to win the inaugural Volvo Golf Champions event in Riffa, Bahrain. He shot 4-under 68 to finish at 268, edging Peter Hanson, who missed an up-and-down from the greenside bunker, and Miguel Angel Jimenez, who birdied No. 18 to finish at 269.
