Mirza downed her opponent from Uzbekistan 6-2, 6-2 to reach the quarterfinals here for the third straight year.

Mirza has been working her way back into shape after missing two and a half months earlier this season due to knee surgery.

Wednesday's victory marked the first time she has put together back-to-back victories since February.

Mirza now awaits the winner of the second-round match between ninth-seeded Jill Craybas of the United States and Olga Govortsova of Belarus.

Top-seeded Russian Anna Chakvetadze also reached the quarterfinals, defeating Romanian qualifier Anda Perianu 6-4, 6-3.

Perianu had recorded her first WTA Tour match win on Tuesday when she beat Melinda Czink in the first round.

But she couldn't stop world number eight Chakvetadze, who has won titles at Hobart and S'Hertogenbosch already this season.

The only other seeded player in action, No. 7 Akiko Morigami of Japan also had an easy second-round match.

A finalist here in 2005, Morigami dispatched German teenager Angelique Kerber 6-2, 6-2.

In other second-round action, American Lilia Osterloh topped Georgian qualifier Anna Tatishvili 7-5, 6-1, whilein the first round China's Yuan Meng defeated Australian Casey Dellacqua 6-4, 4-6, 6-2.
