Thongchai Jaidee beat Stephen Gallacher and Victor Dubuisson in a play-off to capture the Nordea Masters in Sweden.
The Thai bagged his sixth European Tour win by sinking a three-foot birdie putt at the first extra hole after he, Scotland's Gallacher and Frenchman Dubuisson had all posted 16-under in regulation play at PGA Sweden National in Malmo.
Robert-Jan Derksen was a shot further back in fourth while home hero Henrik Stenson had to settle for fifth after bogeying the last when a birdie would have got him into the play-off.
Jaidee was the first to post 16-under after a superb closing seven-under 65. The 44-year-old started with three straight birdies to be out in 33 and came home in 32 after an eagle at the 11th and two more birdies at 14 and 15.
Dubuisson was next to hit that mark after a 67 which featured five birdies in his first 11 holes but seven pars to close while Gallacher made it a three-way play-off after recovering from a bogey at 17 by holing a 20 footer for birdie at the last.
All three men couldn't reach the par five 18th - the first extra hole - in two and the door was left open for Jaidee when Dubuisson could only wedge to 25 feet and Gallacher to 15.
The Thai took the opportunity in style as he put his third to just three feet.
Dubuisson and Gallacher both couldn't hole their birdie tries, allowing Jaidee to stroke in the winning putt and raise his arms to the sky in celebration.
World No 2 Stenson, looking to win on home soil for the first time having twice been a runner-up in this event, had looked set for victory when he birdied three of the first six holes.
He nailed a 20 foot putt at the second, added another birdie from six feet at the fourth and moved to 16-under and into a two-shot lead by draining a 25 footer at the fifth.
But bogeys at six and nine checked the 38 year-old's progress and he was left needing a birdie at the last to join the play-off.
Despite a good tee-shot, he leaked his second right and from there he could only make bogey after chipping his third into sand.
Fellow Swede Robert Karlsson posted the low round of the day, a nine-under 63 which featured seven birdies and an eagle and lifted him into tied sixth with England's Eddie Pepperell and Spain's Alvaro Quiros.
