SAINT-QUENTIN-EN-YVELINES, France — Marcel Siem of Germany shot a 4-under 67 on Sunday to win the French Open, edging Francesco Molinari of Italy by one stroke.
Siem had five birdies and one bogey to finish at 8-under 276, earning his second European Tour title. He also won the 2004 Dunhill Championship in South Africa.
Molinari started the round in 22nd place, six strokes off the lead. He dropped two shots on his opening hole but then sank nine birdies to shoot a 64 for the lowest round of the day.
Raphael Jacquelin of France had a 69 to finish third, two strokes off the pace.
Overnight leaders David Howell of England and Anders Hansen of Denmark bogeyed two of their first three holes to surrender the lead to a group of four tied at 6 under — Ian Poulter, Jacquelin, Siem and Molinari.
Despite gusts of wind reaching 21 miles per hour, Molinari managed to set a target of 277 for the other contenders.
Siem took a two-stroke lead with short birdies on the 14th and the 15th, while Poulter and Henrik Stenson of Sweden tied Molinari by picking up a shot on the 16th.
But Poulter’s momentum stalled when he bogeyed the penultimate hole. The Englishman closed with a 69 to share fourth with compatriots David Lynn and Howell at 279.
Siem had a minor scare on the par-4 final hole when he pulled his tee shot into a bunker. But he recovered by hitting his third shot within 15 feet of the flag.
Siem knew the victory was his when his playing partner Stenson fluffed his third shot across the green and into the water for a triple bogey to slip to seventh place, tied with American Brendan Steele at 280.
