Ivanovic spent 12 weeks at No. 1 after winning the French Open in 2008. Her next opponent is No.4 Angieszka Radwanska, who is on a 12-match winning streak. Fourth-seeded Radwanska won her 12th match in a row with a 6-3, 6-1 victory over Britain's Heather Watson.

Meanwhile, Sixth-seeded Li Na has also advanced to the fourth round with a 6-4, 6-1 win over Sorana Cirstea of Romania. Li will next play Julia Goerges of Germany, who beat Zheng Jie 6-3, 1-6, 7-5 earlier Friday.

Li, the 2011 French Open champion, is trying to add a second Grand Slam title, and the Australian Open appears to be her best chance. She advanced to the 2010 semifinals, the 2011 final - losing to Kim Clijsters - and the fourth round here last year.
