The Williams sisters held court at the Australian Open on Thursday, a back-to-back Venus-Serena doubleheader that left the siblings still in the mix for yet another Grand Slam singles title.

Serena Williams, the Australian Open defending champion who has 11 major singles titles, beat Petra Kvitova of the Czech Republic 6-2, 6-1. Venus, who has seven, defeated Austrian Sybille Bammer 6-2, 7-5.

Serena, who has won the Australian Open every odd-numbered year since 2003, was more dominant, completing her match in just over an hour and converting four of her 11 break-point chances.

Venus Williams has been to the final at Melbourne Park just once, when she lost to her sister in 2003. She faced her second left-hander in a row – she beat Lucie Safarova in the first round.

U.S. Open finalist Caroline Wozniacki of Denmark advanced 6-3, 6-1 over Julia Goerges of Germany and will next play No. 29 Shahar Peer of Israel, who beat Tsvetana Pironkova of Bulgaria 6-1, 6-4.

Wozniacki could play Venus Williams in the quarterfinals.

Other women advancing were No. 7 Victoria Azarenka of Belarus, No. 9 Vera Zvonareva of Russia, No. 10 Agnieszka Radwanska, No. 16 Li Na of China and No. 32 Carla Suarez Navarro of Spain.
