American Collin Morikawa birdied the final three holes to win his first US PGA title at the Barracuda Championship in only his sixth start as a tour professional.
The 22-year-old, who graduated from the University of California in May, on Sunday finished on 47 points, three more than US runner-up Troy Merritt in the only US tour event that uses the Modified Stableford scoring system.
The former world amateur number one made his pro debut at last month's Canadian Open, shared second three weeks ago at the 3M Open and shared fourth two weeks ago at the John Deere Classic to secure a spot on next season's tour.
"It was something really special to finally get the win," Morikawa said.
"I think the gates are open. I've been knocking on the door the past month or so. I've been playing well. I just believed in myself, was able to make some shots and come through."
"When I hit it I knew it was dead center. It felt good to make the putt but I knew it wasn't over. I knew I had business to do on 18."
"My heart was beating really fast," Morikawa said of watching the final drama unfold. "It's something I've got to get used to."
