Ace shuttler Saina Nehwal emerged lone Indian survivor in the singles event thumping Hung Yung Chan of Hong Kong.

She has thus stormed her way into the quarter-finals of the Yonex Sunrise Indian Open Grand Prix to be played on Friday.

Women's second-seed Saina rode on the unforced errors of her opponent and hammered her 21-8, 21-8 to set up a last-eight clash with fifth-seed Xian Wong of Malaysia.

Meanwhile, Jwala weaved magic along with mixed doubles partner V Diju and doubles pair Shruti Kurian to notch up a double victory today.

Second-seed Jwala and Diju beat Xiaolong Liu and Jinhua Tang of China 21-10, 21-15 in just 21 minutes to set up a clash with another Chinese pair of Tao Jiaming and Xiaoli Wang in the mixed doubles quarter-finals.

Jwala then teamed up with Shruti and the duo kept aside their differences to get past compatriots Pradnya Gadre and Prajakta Sawant 21-15, 19-21, 21-15 in the women's doubles match.

India's top ranked women's doubles pair will meet the Malaysian-Singaporean duo of Chiou Hwee Haw and Yujia Li in Friday's quarter-final clash.

In men's singles, former Olympic gold medallist Taufik Hidayat waltzed past Arvind Bhat 21-14, 21-11 while Anup Sridhar was left cursing his luck after going down 21-9, 19-21, 18-21 to Chun Seang Tan of Malaysia. Anand Pawar was humbled 12-21, 12-21 by tournament giant-killer Long Chen of Malaysia.

In women's singles, PC Thulasi played her heart out before going down 11-21, 18-21 to sixth-seed Yu Hirayama of Japan, while Sampada Sahastrabuddhe went down 18-21, 17-21 to Beiwen Zhang of Singapore.

Qualifier Ashwini Ponnappa also hit dead end after losing 16-21, 16-21 to Julia Pei Xian Wong.

World number nine Saina used the court well and played better at the net and her opponent just couldn't gauge the length of the court and kept sending the shuttle out for a walk.

However, Saina wasn't complaining as she grabbed the points and pocketed the first set 21-8.

Chan played better in the next game but could not match the class of the Indian and kept losing points before Saina sealed the game and match at 21-8.

"She was playing well but I gauged the condition and the court quicker then her. I had seen her play yesterday and knew her defence was weak," Saina said after the match.
