The tour's top players are (or, in some cases, were) in Brisbane to start the 2013 season, but it has been a less than auspicious beginning for some of them. Both Sam Stosur and Caroline Wozniacki went out in the first round, with Stosur losing to Sofia Arvidsson, and Wozniacki losing to Ksenia Pervak.
Today, Petra Kvitova, the 2011 Brisbane champion, lost to Anastasia Pavlyuchenkova. Qualifier Pervak saved four match points and advanced with a second round win over Urszula Radwanska, and Daniela Hantuchova beat Sara Errani.
In the meantime, Maria Sharapova withdrew from Brisbane because of her collarbone injury.
Also of note: Jelena Jankovic has withdrawn from the tournament in Shenzhen (reason unknown--at least to me).
