Though Iveta Benesova has since been defeated by Kim Clijsters, the Czech player removed the top seed during her stay in Brisbane. Benesova beat Stosur in straight sets (when Benesova's serve is working, it's pretty dangerous).
Stosur wasn't the only one to go. Serena Williams gave Daniela Hantuchova a walkover in the quarterfinals after she sprained her ankle in her match against Bojana Jovanovski. Williams' health for the Australian Open is in question, but this isn't the first time that she has had physical issues prior to the commencement of play in Melbourne.
Number 2 seed Andrea Petkovic also failed to get past the quarterfinals. She was defeated 5-1, 7-6 by Kaia Kanepi. Kanepi hit 12 aces in the match.
3rd seed Francesca Schiavone is bringing the drama early this year. In a 2-hour, 56-minute match, the Italian saved two match points and defeated Jelena Jankovic 5-7, 7-6, 6-3.
Meanwhile, in Auckland, top Sabine Lisicki retired (surprise!) in her quarterfinal match against countrywoman Angelique Kerber; Lisicki has an abdominal injury. 2nd seed Peng Shuai was defeated in the second round by Lucie Hradecka.
