No. 1 seed Victoria Azarenka knocked off No. 7 seed and defending U.S. Open champion Samantha Stosur in three sets on Tuesday, 6-1, 4-6, 7-6 (7-5), to advance to the semifinals.
Azarenka had to fight for the win after Stosur shook off an uncharacteristically sluggish start to force a third set tiebreaker. But Azarenka was able to finally pull out the win in what had to be one of the toughest draws for a No. 1 seed in awhile.
Azarenka looked dominant early as Stosur struggled to find any sort of groove. But Stosur would go out like a champion in forcing the tiebreaker and putting Azarenka on her heels. Azarenka had to earn every last bit of this match.
Stosur served trailing 5-4 in the third set after Azarenka held serve to take the lead and then Stosur returned the favor by holding her own serve to make it 5-5. It went back and forth again, eventually leading to a tiebreaker that Azarenka won, 7-5. Azarenka was up 4-0 in the tiebreaker before Stosur closed it to 5-5.
Azarenka will now face the winner of No. 3-seed Maria Sharapova and No. 11-seed Marion Bartoli in the semifinals and will keep her No. 1 world ranking no matter the result of the remainder of the tournament.
