Jason Day stayed strong down the stretch to record a two-shot victory in the Wells Fargo Championship at Quail Hollow in North Carolina.
The Australian carded a final-round two-under-par 69 to finish at 12-under 272 - two shots clear of Aaron Wise and Nick Watney. But his victory wasn't without drama.
The former World No.1 suffered back-to-back bogeys on 13 and 14 which dropped him back into a tie with Wise but, with the tournament wide open again, Day posted birdies at 16 and 17 to move clear and closed out victory with a par at the 18th.
It gave him his second win of 2018, the 12th PGA Tour victory of his career and took the 30-year-old up to No.2 in the FedEx Cup standings.
"I felt like I went 10 rounds out there, just fighting against myself," Day said after his triumph. "Aaron played tremendous golf coming in. I didn't have the best day off the tee and even into the greens, but I had a really good day on the greens and around the greens.
"It's special. I mean, obviously I think I've had some tough finishes before with wins and I remember specifically Bay Hill, but this was probably the toughest with how I was driving it out there, you know, hooking the ball in the water on 14 and not knowing what was going on, how Aaron was playing."
Day won the 2015 US PGA Championship but is now keen to add to that solo major victory.
"My next step is to try to win a major this year," he added. "It would be nice to be able to capitalise on the good play, and if I can do that, hopefully the US Open comes around nicely for me."
Day is 16/1 to win next month's US Open at Shinnecock Hills on Long Island, New York while he is 25/1 to land July's Open Championship at Carnoustie.
