Maria Kirilenko of Russia defeated Ana Ivanovic 6-3, 6-1 in the third round on Wednesday to eliminate another seeded player at the Pan Pacific Open.
Kirilenko, who knocked out US Open champion Samantha Stosur on Tuesday, broke her opponent in the first game of the second set and was never threatened by the 12th-ranked Serb, who took a medical timeout midway through the second set because of a sore back.
In other third-round matches, Vera Zvonareva of Russia defeated Iveta Benesova of the Czech Republic 6-1, 6-2, while seventh-seeded Marion Bartoli of France coasted to a 6-2, 6-1 win over China's Peng Shuai.
Maria Sharapova, the tournament's No. 2 seed, will face Julia Goerges of Germany, and top-seeded Caroline Wozniacki of Denmark faces Kaia Kenepi of Estonia later on Wednesday.
