Tommy Fleetwood moved to the top of the Race to Dubai Rankings presented by Rolex as he won the second Rolex Series event at the HNA Open de France.
The Englishman arrived at Le Golf National as one of the form players on the European Tour but with a poor record on the course that will host next year's Ryder Cup having never made the cut or even broken par in Paris.
He put that right in some style with a closing bogey-free 66 that gave him a 12 under par total and a one-shot victory over American Peter Uihlein.
For Uihlein there was the consolation of earning a spot at the Open Championship along with home favourite Mike Lorenzo-Vera and Swede Alexander Björk, who both finished in a share of third at eight under alongside Dane Thorbjørn Olesen.
The victory is Fleetwood's second of the season after the HSBC Abu Dhabi Championship and the winner's cheque of 1,040,824.34 euros moves him above the season's only other multiple winner so far - Sergio Garcia - to the top of the European standings.
Fleetwood also has four other top fives this season including at the WGC - Mexico Championship and US Open Championship and this victory will move him into the top 20 in the Official World Golf Ranking.
"Today, it's a day that I'll never forget," he said. "The way I felt coming down the stretch, the holes and the shots you have to hit.
"Winning, it's the best feeling by far in golf and to do it on this golf course in this event, a Rolex Series event, just massive, massive bonuses.
"It's just been a great week from start to finish. Coming off the back of good golf, US Open and BMW in Germany, felt like I've been swinging it well. So it's good to put it into practice and I've just kept up good form.
"With the start I had this year, it's very easy to look at the Race to Dubai and want to look towards the end of the year. Winning the Race to Dubai, it's going to be tough.
