DOHA, Qatar (AP) -- Alvaro Quiros won the Qatar Masters on Sunday, making five birdies on the back nine to shoot a 3-under 69 and beat Louis Oosthuizen and Henrik Stenson by three strokes.
The 26-year-old Spaniard finish at 19-under 269 at the Doha Golf Course after a round that included seven birdies and four bogeys.
