(CNN) -- Germany's Martin Kaymer beat Lee Westwood of England at the first hole of a sudden death playoff to win the French Open at Le Golf National near Paris on Sunday.
Kaymer celebrates with champagne after his playoff victory.
Both men had been tied at 13-under after regulation play, but Westwood failed to carry the lake at the 18th, the first extra hole, and ran up a double bogey.
Kaymer, who only just cleared the water himself, had two putts for victory from 18 feet but rolled home his first effort to claim his first win of the season which puts him back into the world's top 20.
"This is obviously very special for me. I had some good chances, but finally I won it, so it's good," Kaymer told the UK Press Association.
Westwood, who was searching for his first victory since September 2007, has now lost three playoffs since his last title.
He had shot a six-under 65 to power his way to the top of the leaderboard and despite being disappointed by the playoff mistake was pleased by the improvement in his play.
"You can't judge the week by that and I certainly can't be disappointed by anything after the way I played today."
Ryder Cup captain Colin Montgomerie, second at the tournament last year, is is still searching for his first top 10 finish since then.
He moved to nine-under but four dropped shots from the 15th saw him finish 13th.
England's Ian Poulter finished third -- three shots behind -- after a closing 67 with Denmark's Anders Hansen and Peter Hanson of Sweden a further shot back.
Argentina's Rafa Echenique, who held a one-stroke lead over Kaymer overnight, collapsed to a 77 to share 13th after triple-bogey sevens on both the 15th and 18th.
