Thomas Bjorn became the 28th man to win back-to-back European Tour titles with a four-shot victory at the Omega European Masters.
The Dane, who prevailed in a five-man play-off at last week's Johnnie Walker Championship, fired a nine-under final round of 62 at Crans-sur-Sierre for a 20-under-par total.
Starting the day three back, he had five birdies on the front nine, including four in a row from the fifth to make early inroads on a packed leaderboard.
Martin Kaymer missed a two-foot putt on the long 14th that would have taken him two in front and how Bjorn made him pay.
He followed a birdie at the 14th with an eagle three at the next to snatch the lead from the German.
And holding a two-shot advantage with two holes remaining, Bjorn sealed the win in style with birdies at both the 17th and 18th.
That left him four better off than Kaymer, who finished on his own in second place at 16-under-par.
"Only parring the 14th and 15th hurt me, especially missing the two-foot putt," said world number five Kaymer, who could have moved up two places in the rankings with victory.
"I didn't come here to finish second, I wanted the win and to go to third in the world. But I'm hitting the ball so well I'm optimistic about trying again next week."
Bjorn has had a real rollercoaster career, talking of "fighting demons" after he lost the 2003 Open from three ahead with four to play and going through another low this summer following the death of his father.
But with a third win of the year - world number one Luke Donald is the only other player to do that - Bjorn is now back in the world's top 30 and, of course, leads the Ryder Cup race.
US Open champion Rory McIlroy (68), South Africa's Jaco Van Zyl (64) and overnight leader Jamie Donaldson (70) shared third, a stroke behind Kaymer.
World number two Lee Westwood (70) was part of a three-way tie for sixth at 14 under, alongside fellow Englishman David Lynn (65) and Sweden's Fredrik Andersson Hed (64).
