Antoine Rozner landed his first European Tour title as a closing 64 gave the Frenchman victory in the Golf in Dubai Championship.
Ahead of taking part in next week's highly lucrative World Tour Championship, also in Dubai, Rozner finished two clear of the field after toppling overnight leader Andy Sullivan.
As Englishman Sullivan wobbled, closing with a two-under 70, Rozner took full advantage as he picked up five shots from the ninth to the 13th, with three birdies and an eagle.
The Parisian completed an eight-under round with another birdie at 18, reaching 25 under par for the week, with Sullivan sharing second place with fellow Englishman Matt Wallace, France's Mike Lorenzo-Vera and Italian Francesco Laporta.
Rozner's success came in just his 24th European Tour event, the fewest any French golfer has played before winning for the first time.
Scotland's Grant Forrest jumped 15 places to finish sixth thanks to a closing 63, the lowest score of the day.
Rozner had begun the day four shots adrift of Sullivan, and the turnaround saw the champion collect prize money of €160,342, the biggest pay day of his fledgling career on the tour.
"It means a lot," Rozner said on the European Tour website.
"It's such a strange year, we have been through so much all over the world and to be able to get it done today in such nice fashion, eight under. It's amazing.
"I'm going to be very honest with you, the first time I saw I was in the lead was on the 18th green so I didn't really look at the leaderboards.
"I knew the game was there. I didn't know it was that good."
Now he can target more Dubai success next week, saying of that prospect: "It's a good way to finish the season and the biggest tournament of the year of course. I didn't play any Rolex events this year so to be able to play such a big tournament is going to be a big thing for me so I'm excited."
