Carl Pettersson didn't feel the pressure Sunday until trying on the tartan jacket.
Then it all sank in.
The 34-year-old native of Sweden coasted to a five-shot victory at the RBC Heritage Presented by Boeing, posting 14-under to win over Zach Johnson and Colt Knost, who was one off the lead entering the final round but struggled out of the gate.
Pettersson secured $1,026,000 with the victory, his fifth on the PGA Tour.
Never miss a local story.
"I knew I was playing well," Pettersson said. "I didn't want to put too much pressure on myself. I was kind of downplaying the whole thing."
Beaufort resident Mark Anderson enjoyed his best tournament as a professional, finishing 3 under, tied for 13th and earning $106, 875. Bluffton resident Kyle Stanley finished 6 over and slipped to a tie for 60th.
Pettersson made birdies at Nos. 1, 4 and 5 to create a cushion, by that time over second-place Johnson, who finished 9 under.
Pettersson led the field in greens in regulation and in putts per greens in regulation -- a devastating combination at Harbour Town Golf Links, which sports the smallest greens of any PGA Tour course.
Anderson made five birdies on Sunday to post 68, his best round at Harbour Town.
"It feels really good," Anderson said. "It was an exciting week the entire week, especially today, playing really well in the final round on a tough day."
