Long-time partners (and bitterly-split ex-partners) Cara Black and Liezel Huber competed against each other in doubles at the Australian Open quarterfinals on Tuesday, with Huber and Nadia Petrova defeating Black and Anastasia Rodionova 6-1, 6-4. Top seeds Gisela Dulko and Flavia Pennetta also advanced, with a 6-0, 6-3 win over Natalie Grandin and Vladimira Uhlirova.
2nd seeds Kveta Peschke and Katarina Srebotnik won in straight sets over 9th seeds Bethanie Mattek-Sands and Meghann Shaugnessy, and 12th seeds Victoria Azarenka and Maria Kirilenko defeated Chuang Chia-Jung and Hsieh Su-Wei.
I assume that the Azarenka-Kirilennko pairing is a temporary one. Agnieszka Radwanska, Kirilenko's usual partner, was not expected to play, and was not able to make a firm decision about playing until the last minute.
