The 46-year-old Swede shot 11 under par at Trump National Golf Club Bedminster, which hosted the third LIV Golf event since its launch in June, finishing ahead of Americans Matthew Wolff and Dustin Johnson.
“I guess we can agree that I played like a captain,” Stenson said after his victory. “It’s been a good first week, obviously, nice to be here with the guys and get an idea. Like I said, it’s been a busy 10 days and I’m extremely proud that I managed to concentrate as well as I did.”
Stenson shot a two-under 69 in the final round on Sunday to finish two shots ahead of Wolff and Johnson after taking the lead alongside Patrick Reed in the first round shooting 64.
“The first day in particular, I played really, really solid. Yesterday was a bit more difficult, and today we played pretty well for most of the rounds. It was a bit wobbly coming in. home, but we’ll take it at the end,” Stenson said.
Elsewhere, Phil Mickelson’s struggles continued as he finished near the bottom of the standings with a par-six on the tournament.
In the tag team competition, Stenson’s Majesticks GC, led by Lee Westwood, finished second to Johnson’s 4 Aces GC, who shot 25 under par to claim the $3 million prize.
The next LIV Golf event is scheduled to take place September 2-4 at The International’s Oaks Golf Course in Bolton, Massachusetts.
