Victor Dubuisson captured the Turkish Airlines Open in Antalya after a thrilling finish at the Montgomerie Maxx Royal.
The 23-year-old claimed his first European Tour title by two shots as his closing three-under 69 and 24-under total was just enough to hold off a dramatic late charge from Welshman Jamie Donaldson.
Dubuisson, who started the day with a five-shot lead, looked to be doing just enough to keep the chasing pack at bay despite starting with nine straight pars while his rivals poured in birdies behind him.
But the tournament was thrown wide open by a dramatic hole-in-one from Donaldson at the par three 16th.
That ace and a bogey by Dubuisson at 14 saw the Frenchman's three-shot advantage wiped out in a heartbeat and when moments later Justin Rose sank a birdie putt at 16 there was suddenly a three-way tie for the lead at 21-under.
The Frenchman recovered heroically though, going a shot in front again with a tap-in birdie at 15 after a superb second.
Donaldson looked set to throw one more big punch when he found the par five 18th in two but his eagle putt to take the lead stayed left.
His birdie for a nine-under 63 briefly tied the lead again but Dubuisson regained it on his own after sinking a 25 footer at 17 and that meant the man from Cannes needed a par rather than a birdie at the closing hole.
Despite missing the fairway, he muscled an iron to just short of the green and a lovely chip sealed the deal before, for good measure, he rolled in the eight footer for birdie to secure a two-shot winning margin.
Rose, who reached the turn in just 29 after four birdies and an eagle, made further gains at 13, 14 and 16 to tie the lead but a bogey at the last left him four back after a closing 65.
Tiger leaves it too late
Tiger Woods made an early move with birdies at three, four and six but his challenge petered out with bogeys at seven and 11.
Woods refused to give in though and four birdies in the last six holes gave the world number one a 67 and elevated him into a tie for third with Rose.
Ian Poulter, who started the day as Dubuisson's nearest challenger, closed to within two after a birdie at 11 but from there he saw a series of putts shave the hole.
A bogey at 12 stopped his momentum and six closing pars meant he had to settle for a tie for fifth with Frenchman Raphael Jacquelin, who had carded a course record 62 in the third round.
Race to Dubai leader Henrik Stenson finished in a tie for seventh although his lead at the top of the standings has now been cut by Rose who moves into second.
The top four going into next season's finale in Dubai are Stenson (2,379,193), Rose (2,165,726), Graeme McDowell (2,057,394) and Poulter (2,035,286).
