Jon Rahm moved up to No.2 in the world rankings after outlasting Andrew Landry in a dramatic play-off at the PGA Tour's CareerBuilder Challenge in California.
The Spaniard had shot a final-round 5-under-par 67 on the Stadium Course at La Quinta to set the clubhouse target of 22-under but Landry birdied the 18th to match him.
Landry twice had putts in the play-off to win but Rahm delivered the knockout blow on the fourth extra hole to walk away with the trophy.
The 23-year-old has now won two of his last three worldwide starts and finished runner-up to World No. 1 Dustin Johnson in the other.
"It's hard to believe, to be honest, passing Jordan Spieth, three-time major champion," said Rahm. "I only have two wins, he's got 10 plus, right?
"I said it many times, I never thought I was going to be at this point in my life right now. Incredibly proud of myself, my whole team, my caddie Adam (Hayes), he does an outstanding job of keeping me calm."
Talking about the play-off, Rahm said: "I was just scared that Andrew was going to take the lead hand and make the putt.
"I just got fortunate that none of us really made any and I was able to make the one that mattered. But then again, it was really supreme ball striking on my part today. Especially on the back nine I hit the ball as good as I can, didn't miss many shots.
"I'm excited it happened the way it did because it's going to make me be a better player."
Rahm now heads to Torrey Pines, the scene of his first PGA Tour win, to defend the Farmers Insurance Open title.
Looking ahead, Rahm is 23.00 to win the Masters in April and 19.00 to land July's Open Championship at Carnoustie.
