ranked Caroline Wozniacki came back from 4-0 down in the final set to beat Dominika Cibulkova of Slovakia 7-5, 2-6, 6-4 Tuesday and advance to the quarterfinals at the Sydney International. The match ended on a line call that was ruled in but later, on video review, shown to be out by a few millimeters, giving Wozniacki victory on her second match point. Wozniacki, who was No. 1 for all but one week of last year, has achieved the top ranking without having won a Grand Slam. The Danish player's best finish in four appearances at the Australian Open, which begins next Monday, was the semifinals last year. Wimbledon champion Petra Kvitova, ranked No. 2 and who could overtake Wozniacki for the top spot with a win at Sydney, also struggled against an unseeded opponent before advancing to the quarterfinals with a 7-5, 3-6, 6-4 win over Alexandre Dulgheru of Romania. Kvitova used a strong serve to set up an easy crosscourt forehand at the net to the open corner for the win on her first match point. In other second-round matches, third-seeded Victoria Azarenka of Belarus beat Jelena Jankovic of Serbia 6-4, 6-2, French Open champion Li Na beat Channelle Scheepers of South Africa 2-6, 6-4, 6-1 and seventh-seeded Agnieszka Radwanska of Poland defeated Andrea Petkovic of Germany 7-5, 6-4. Daniela Hantuchova of Slovakia defeated 2010 French Open champion Francesca Schiavone of Italy 7-5, 6-1. Former US Open champion Svetlana Kuznetsova withdrew from her match against Lucie Safarova while down 6-1, 2-0, citing heat illness. In men's matches, fifth-seeded Viktor Troicki of Serbia beat former No. 1 Lleyton Hewitt of Australia 4-6, 6-3, 6-2 and eighth-seeded Radek Stepanek of the Czech Republic defeated Xavier Malisse of Belgium 6-7 (4), 6-4, 6-4.

Wickmayer advances Top-seeded Yanina Wickmayer of Belgium beat Australian wild-card entry Casey Dellacqua 6-1, 6-1 Tuesday to advance to the quarterfinals of the Hobart International. Fourth-seeded Angelique Kerber of Germany also reached the quarters by defeating Italy's Sara Errani 6-1, 6-2, and Sorana Cirstea of Romania ousted Bethanie Mattek-Sands of the United States 2-6, 6-3, 7-5. In first-round play, Sacha Jones beat Kristina Barrois of Germany 6-1, 6-4 to set up a meeting with Shahar Peer, who beat Lucie Hradecka of the Czech Republic 6-3, 6-1. The winner of that match will play 2007 champion Anna Chakvetadze, who defeated Bulgaria's Tsvetana Pironkova 6-3, 6-2 in a second-round match Tuesday.
