Sepp Straka overcame some late nerves to claim his third PGA Tour title with a win at The American Express at La Quinta in California.
The Austrian carded a two-under-par 70 in the final round to finish two shots ahead of American Justin Thomas.
The European Ryder Cup player led by four shots on the final day but came under pressure when the American hit five shots on the front nine.
But the former world number one – a two-time major champion – only made one birdie on the back nine, meaning Straka held on despite two late shots.
“Nerves, complete nerves,” said Straka, who did not have a bogey in the tournament until the 16th hole on Sunday.
“Stomach is in knots, all nine. So I'm really excited about the way I'm handling the pressure.”
Justin Lauer from the United States and Australian Jason Day tied for third place with 22 points, while American duo Charlie Hoffman and Patrick Cantlay fell behind by two goals.
