Padraig Harrington and Shane Lowry saw their Turkish Open chances scuppered as Justin Rose hit form at just the right time.
Three birdies in his last four holes were enough for the English man to claim a one-shot win in Antalya, his second Tour win in a row.
Triple-major winner Harrington was just one shot off the lead coming down the 17th but up ahead Rose drained a 12-footer to push further out his lead.
That left the Dubliner needing to hole his second shot on the last to force a play-off but a valiant effort, which had the line but not the length, fell short and meant the €985,495 prize went to Rose - his second title in the space of seven days after also winning in Shanghai last week.
Rose finished on 18 under, one ahead of the Belgium’s Nicolas Colsaerts and Dylan Frittelli of South Africa.
The highlight of Harrington’s round was a long-distance par save on the tenth when he looked certain to drop a shot before chipping in.

The Dubliner also landed an eagle on 15, which momentarily saw him joint top of a crowded leaderboard.
His 67 also included two bogeys and four birdies.
Lowry, who was co-leader overnight, never got into his stride.
The Offaly man bogeyed his second but then failed to pick up a shot until the 12th, his only birdie of the day.
A bogey on the par-5 15th finished effectively ended his chances and he had to settle for a share of eighth on 13 under.
Wicklow's Paul Dunne began the day six off the lead and did pick up a shot on the second but three bogeys between six and nine saw him drop down the field, eventually carding a one-over-par 72 to share 23rd spot on eight under.
Rose's win sets up a thrilling finale to the European Tour campaign.
He began the week trailing fellow countryman Tommy Fleetwood by more than one million points but has now closed the gap on the money-list leader to just over 71,000 points with two tournaments remaining this season.
