Thongchai Jaidee of Thailand won the French Open by four strokes for his eighth victory on the European Tour, as Rory McIlroy failed to deliver a final-round surge on Sunday.
Jaidee, who was the overnight leader, shot a 3-under 68 to finish on 11-under 273 at Le Golf National outside Paris, where the 2018 Ryder Cup will be staged. After his impressive display of front-running, he collected $650,000 for the biggest cheque of his career.
Francesco Molinari finished in second place after shooting 66, the lowest round of the final day.
McIlroy started the round two shots behind Jaidee, but bogeyed No. 3 and made his only birdie on No. 14. He shot an even-par 71 and was a stroke behind Molinari in third place.
Brandon Stone, Alex Noren, Callum Shinkwin and Richard Sterne all qualified for the British Open after finishing in the top 12.
