France’s Victor Dubuisson won the Turkish Airlines Open for the second time as he carded a final round 66 to finish 22 under par.
Rory McIlroy, who began the fourth round a shot off the lead after three consecutive 67s, finished a disappointing sixth.
The world number three could only manage a final round of 71, including bogeys on the eight, ninth and 12th.
Dubuisson won by one shot ahead of South Africa’s Jaco van Zyl, with Thailand’s Kiradech Aphibarnrat a further shot back.
