GREENSBORO, N.C. — Henrik Stenson kept making birdies on the back nine Sunday at the Wyndham Championship. They added up to a tournament record — and his first victory of the year.

Stenson closed with a 6-under 64 for a one-stroke victory in the final event of the PGA Tour regular season.

The 2013 FedEx Cup champion finished at 22-under 258 at Sedgefield Country Club, breaking the course’s 72-hole record set by Carl Pettersson in 2008 and matched last year by Si Woo Kim.

The Swede earned $1,044,000 and 500 FedEx Cup points for his sixth win on tour and his first since the 2016 British Open.

“It’s certainly a good time to start firing,” Stenson said. “We know the kind of damage you can do in the playoffs. ... If you get hot and keep on playing well, you have a chance to challenge.”

Stenson said he left his driver in his locker all week — “he’s a little anxious to get out there and start getting some air time next week,” he quipped of the club — and certainly didn’t need it on the par-70 Sedgefield course.

For the second straight day, he had four birdies in a five-hole stretch of the back nine.

Ollie Schniederjans shot a 64 to finish second. Webb Simpson was 18 under after a 67.”

“I had to keep on making birdies,” Stenson said, “because Ollie was surely not backing down.

Stenson had three consecutive birdies on Nos. 15-17 — leaving a 20-foot eagle putt on the 15th hole about a foot short — after he and Schniederjans were both at 19 under.
