In the semifinal on Saturday, Saina will meet fourth seeded Eriko Hirose of Japan who beat fifth seeded Jie Yao of the Netherlands 21-19, 10-21, 22-20 in another quarterfinal match.

Saina is the only Indian women left in the fray in singles as compatriot Aditi Mutatkar had crashed out in the first round.

In the men's section, no Indian is left in the fray with Ajay Jayaram, Chetan Anand and Parupalli Kashyap and Gurusaidatt RM Venkata already out of the singles competition.
