Victoria Azarenka overcame a letdown set tiebreaker to upend Agnieszka Radwanska 6-7 (0-7), 6-0, 6-2 in their quarterfinal match at the Australian Open on Tuesday.

Azarenka, seeded third, will play in her second Grand Slam semifinal against either top-ranked Caroline Wozniacki or reigning champion Kim Clijsters, who are currently playing at Rod Laver Arena.

There were eight breaks of serve in the first set alone between Azarenka and the eighth-seeded Radwanska, who won all seven points in a surprisingly quick tiebreaker.

Azarenka bounced back from losing her first set of the tournament quite swimmingly, goose-egging the Pole in a 26-minute second set.

The Belarusian kept the momentum in her favor and controlled the final set to improve to 7-3 against Radwanska, who has yet to reach a major semifinal.

Azarenka still has a chance at reaching the World No. 1 ranking by the end of the week.
