Schauffele rolled in a three foot putt on the 72nd hole to claim the win over fellow American Robert Streb (69). Countryman Jamie Lovemark (69) and Colombia’s Sebastian Munoz (72) were a further stroke back in a tie for third place.

The 23-year-old Schauffele not only captured his maiden PGA Tour win but he has tied up starts in next year’s Masters, the PGA Championship next month and the Open Championship starting at Royal Birkdale on July 20. Streb, Munoz and Lovemark also earned spots at The Open with their high finish.

Schauffele tied for fifth in his first US Open at Erin Hills last month and he says it was that finish that gave him the belief he could win on the PGA Tour.

"The US Open was a huge moment in my career," Schauffele said.

"It was one of the biggest stages, and for me to be calm and collected throughout the week and just kind of hang on and tie for fifth was huge for me mentally. It kind of gave me the confidence and allowed me to play to win this week."

FINAL SCORES

He’s now looking forward to playing more majors but is not getting ahead of himself in terms of thinking he is ready to win a big one … just yet.

“Being a rookie, my only goal was to just make the playoffs and maintain, just stay on the PGA Tour,” he said. “So to get the three or Majors is a bonus for me. I'll keep looking at it like that for now and hopefully that pays off.”

Another rookie, Curtis Luck, was the best of the Aussies for a second consecutive week, carding a final round 68 to finish at six under and T20. Geoff Ogilvy was the next best at even par and T58.
