Macau: Ace Indian shuttler Sania Nehwal survived an early scare from Indonesia's Dinar Dyah Ayustine to book her place in the quarter-finals of the Macau Open Grand Prix Gold badminton tournament here on Thursday.

After going down in the first game, the London Olympics bronze medallist rebounded strongly to register a 17-21, 21-18, 21-12 win over her Indonesian opponent in the women's singles clash that lasted about an hour.

With the win, Saina has now set up a clash against Zhang Yiman of China for a place in last four.

Earlier, the 26-year-old from Hisar kicked off the tournament on a promising note as she registered 21-23, 21-14, 21-18 win over Indonesia's Hanna Ramadini.

However, it was curtains for P Kashyap and men's doubles pair of Manu Attri and B Sumeeth Reddy.

Kashyap, who is on a comeback trail, put up a gallant fight before losing 13-21 20-22 to Lin Yu Hsien of Chinese Taipei in a 45-minute duel.

Third seeds Manu and Sumeeth also fought hard before going down 20-22 19-21 to Singapore's Danny Bawa Chrisnanta and Hendra Wijaya.
