Robert Karlsson of Sweden shot a 7-under 65 to win the Qatar Masters by three strokes on Sunday.
The 40-year-old Karlsson made seven birdies to total 15-under 273 at Doha Golf Club and record his 10th European Tour victory, his first since missing several months last season due to an eye injury.
Alvaro Quiros of Spain, last year's champion, was runner-up after a 67.
Lee Westwood had a share of the lead with three holes to play, but a bogey at the 16th and Karlsson's two birdies at the final two holes ended his challenge. The Englishman shot a 70 to share third place with Brett Rumford of Australia (69) at 277.
