World No.1 Victoria Azarenka extended her domination over Australia’s Samantha Stosur to win her third successive title of the year at the WTA Qatar Open on Sunday.

The Australian Open champion from Belarus showed no signs of discomfort from her overnight injury scare in the semi-finals against Agnieszka Radwanska by beating Stosur 6-1 6-2 in a one-sided final to extend her unbeaten streak in 2012 to 17.

The Qatar Open was Azarenka’s 11th career title, 10 of them coming on hard courts.

Third seed Stosur left the tournament as the first Australian woman to earn more than $10 million in career prizemoney.
