Tiger Woods claimed his second victory in successive weeks when he parred the first hole of a sudden-death playoff with holder Ernie Els at the Dubai Desert Classic on Sunday.
The world number one, who also won the Buick Invitational in San Diego last week, carded a regulation five at the 18th while South African Els took a bogey after finding water with his second shot.

South African Retief Goosen, the world number three, finished in sixth place on 272 after a final-round 71.Swede Henrik Stenson, last week's Qatar Masters winner, was a further stroke back alongside Briton Darren Clarke.
