Carl Pettersson eased to a five-shot victory in the RBC Heritage tournament on Sunday.
The Swede led by one stroke going into the final round but pulled away in the early stages on Sunday's play and was never reeled in at the Harbour Town Golf Links.
Three birdies in his first five holes took him well clear of the field.
Colt Knost, who played alongside Pettersson in the final group, struggled from the off.
He bogeyed the first hole of the day and a triple-bogey at the third effectively ended his chances.
Pettersson finished with a total of 14 under par, five shots clear of Zach Johnson with Knost a shot further adrift in third place.
Brian Davis was the top Briton in joint 13th. He finished on three under for the week.
Pettersson said: "Every win is really special. It's getting harder and harder to win out here.
"But five wins is great. I'm hoping to add to that. I know it's going to take a lot of effort and hard work and dedication, but I hope I can add to it."
On his unusual approach to fitness, Pettersson, one of the larger me on tour, added: "Just because you don't look like an athlete doesn't mean you're not an athlete.
"We're not running marathons here, we're just walking 18 holes. Maybe some of these guys are overdoing it."
