Jim Furyk shot a 4-under 68 on Sunday to win The Ally Challenge in his inaugural event on the Champions Tour at Grand Blanc, Mich.
Furyk, who turned 50 on May 12, finished at 14-under 202 in his three trips around Warwick Hills Golf and Country Club.
Brett Quigley (71 on Sunday) and South Africa's Retief Goosen (66) tied for second at 12 under.
Furyk recorded four birdies in his second straight bogey-free round.
He is the first player to win in his Champions Tour debut since Miguel Angel Jimenez in 2014. Furyk is the 19th player to win his first Champions start.
Furyk won 17 PGA Tour titles, including the 2003 U.S. Open, and Sunday's triumph was his first since the PGA's RBC Heritage in 2015.
"I probably felt better today than I did any day of the week," Furyk said after the victory. "I put a lot of pressure on myself early and Friday I was kind of a wreck on the golf course and was able to kind of chip and putt and scrap my way around for a 68. It was an ugly, ugly 68.
"So that's the one round that kind of saved my week and I think gave me the opportunity to get in position to win. So just excited to be able to come out here, first week and play so well and get a win."
The tournament was the first Champions event since the Hoag Classic, March 6-8, due to the coronavirus pandemic.
Meanwhile, Furyk was able to fight off Quigley down the stretch.
Quigley birdied the par-5, 16th hole to tie Furyk for the lead but then bogeyed each of the final two holes.
"I just got a little sloppy as I was going along and unfortunately didn't do it when I had a chance," Quigley told reporters. "But yeah, I mean, it happens. And, unfortunately, it will probably happen again in my lifetime."
Quigley carded four bogeys on the back nine. He made five birdies on Sunday.
Goosen eagled the par-5, No. 1 and added seven birdies. But he also had three bogeys.
Chris DiMarco's 65 was the low score of the round. He tied with Wes Short Jr. (69) and Australia's Rod Pampling (68) for fourth at 11-under 205.
Tom Lehman (68), Jerry Kelly (69) and Germany's Bernhard Langer (69) were another shot back in a tie for seventh.
Mike Weir, who the 2003 Masters, and K.J. Choi of South Korea also made their Champions' debuts. Both players finished in a tie for 27th at 6-under 210 with Choi shooting 70 on Sunday and Weir a 71.
The final round was delayed about three hours due to heavy rain.
