William Mouw carded a brilliant closing 61 to surge up the leaderboard and claim a one-shot victory at the ISCO Championship.
The American was making just his second start on the DP World Tour - and only 20th on his home PGA TOUR - but is now a winner on both after finishing at ten under, one clear of fellow American Paul Peterson.
The event featured a field of PGA TOUR and DP World Tour members as part of the Strategic Alliance between both tours, with 50 DP World Tour members, featuring a mix of seasoned stars and emerging talent from the HotelPlanner Tour and Qualifying School, teeing it up.
Spaniard Manuel Elvira carded a closing 66 to finish the week in third three shots off the lead, one clear of England's David Skinns and American Vince Whaley.
Mouw made the turn in 30 and then registered four birdies on the back nine and set the target while overnight leader Peterson still had several holes to play.
But Peterson, who had completed his third round in the morning, dropped two shots on the front nine and came up just short despite three birdies on the way home in a 69.
"I'm thrilled to be a PGA Tour Champion, first one," said Mouw.
"Yeah, it was quite the long wait. We finished early. My caddie, Steve, and my wife were able to go to the range and kind of just do our own thing, joke around a little bit.
"But I was mentally ready for a play-off, and if it came to that, I was ready. But that wasn't the case and I'm just blessed to be the winner."
Elvira's third-place finish is his best DP World Tour result since graduating from the HotelPlanner Tour in 2023.
