The women's bracket at the 2013 Australian Open remains relatively upset-free, with No. 2 Maria Sharapova and No. 4 Agnieszka Radwanska both winning in straight sets to advance to the quarterfinals in Melbourne. No. 6 Na Li also won, making No. 5 Angelique Kerbe the only top 7 seed not still playing in the tournament. She lost in straight sets to No. 19 Ekaterina Makarova on Saturday.
There are still four more fourth round matchups to be played Monday. No. 1 Victoria Azarenka will take on Elena Vesnina of Russia just after No. 10 Caroline Wozniacki plays Svetlana Kuznetsova beginning at 7 p.m. ET on Sunday (11 a.m. local on Monday). The winner of those two matches will play each other in the quarters.
No. 3 Serena Williams will play No. 14 Maria Kirilenko on Monday at 3:30 a.m. ET (7:30 p.m. local time), with the winner of that match taking on the winner between No. 29 Sloane Stephens and Bojana Jovanovski.
The quarterfinals will begin Tuesday with the half of the bracket that was set during Saturday's games. Sharapova will take on Makarova, and Radwanska will play Li for the right to go the semifinals.
