Michael Kim produced late fireworks to claim his first worldwide victory in over seven years at the FedEx Open de France.
The American made back-to-back birdies at the 16th and 17th to move into the outright lead with one hole remaining before draining his clutch par putt from 16 feet to seal a one-shot win on 16 under par.
His late heroics denied early clubhouse leader and home favourite Jeong weon Ko the chance to contest a play-off after the French crowd had roared him to a closing 65.
Ko finished alongside Australia's Elvis Smylie in a tie for second on 15 under, one clear of five-time major champion Brooks Koepka.
Kim made a total of six birdies in his spotless final-round 65 to clinch his first title since the 2018 John Deere Classic on the PGA Tour.
He said: "I'm just so happy and grateful that I was able to come out with the victory.
"I've had a really good year on the PGA Tour this year. This feels like the perfect cherry on top and I hope to continue this throughout my career."
England's Marcus Armitage finished in a tie for fifth on 13 under after his 68.
