Steven Fisk beat Taylor Pendrith in a play-off to win the ISCO Championship.
The American carded a closing 67 at Hurstbourne Country Club in Kentucky to finish at 16 under alongside Canadian Pendrith, before prevailing with two-putt par on the third extra hole.
Fisk is now a two-time PGA TOUR winner, having won the Sanderson Farms Championship last year, while this is his first on the DP World Tour in just his fourth start.
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 established stars and emerging talent from the HotelPlanner Tour teeing it up.
Aaron Wise and Ben Silverman finished one shot out of the play-off, while American former Major winner Lucas Glover was unable to capitalise on holding the 54-hole lead as a final-round 71 saw him finish in a tie for fifth at 14 under.
On the first play-off hole, Pendrith - who closed with a 65 in regulation play - missed a nine-foot birdie putt, as Fisk got up-and-down from a greenside bunker to force a second play-off hole which both players parred again.
On the final trip down the par four 18th, Pendrith found a fairway bunker off the tee and then left his approach shot short on his way to a double bogey as Fisk sealed victory with a routine par.
"I love to be in the position [to win]," said Fisk, who climbs to a career-high 79th in the Official World Golf Ranking.
"I crave it like nothing else. It's what we play for.
"I couldn't give a damn about finishing 60th in a golf tournament. This is what I want to do."
Asked what makes this victory special, he added: "Validation, probably. Sanderson Farms last fall was kind of out of nowhere.
"I feel like I have shown spurts of some better golf this year but haven't been able to sustain it so to come out here today and grind my butt off is pretty special."
Spaniard Manuel Elvira was the best placed DP World Tour member for the second consecutive year, backing up a third-place finish 12 months ago with a tie for eighth after a closing 67.
