Jordan Spieth won the AT&T Pebble Beach Pro-Am by four shots for his ninth PGA Tour title in just 100 starts.
The two-time major winner carded a two-under-par 70 at the iconic Californian course to finish on 19-under par.
The 23-year-old Texan, who had led since the halfway stage, hit two birdies in his bogey-free final round, including one from 30 feet on the par-three 17th. He managed to play the final 28 holes of the tournament without a bogey.
“This is a bucket-list place to win,” said Spieth, who made his major breakthrough at the Masters in 2015. “Here, Augusta National, St Andrews, I mean there’s only a few in the world, it feels really special, it was amazing walking up the 18th green knowing that I was going to win. It’s just such a unique position, I tried to soak it in.”
The world No.6 added: “I don’t like playing boring golf, but that’s what was needed and that’s how we closed it out. I could afford to make a couple of mistakes if I needed to, but fortunately I didn’t and managed to stay ahead. It was just kind of a dream round when you are leading by a bunch.”
American Kelly Kraft finished alone in second on 15 under, with Dustin Johnson third on 14 under, and world No.1 Jason Day a further shot back in fourth. Luke Donald was the highest placed Briton, tied for 23rd on six under, two shots ahead of Justin Rose.
