The top-seeded pair routed the hapless French pair of Iryna Bremond and Caroline 6-0, 6-2 in the first round. They will face the local pair of Varatchaya and Varunya Wongteanchai in the last-eight stage. In the singles match today, Sania served extremely well in the second set and put behind an early break to stage a brilliant comeback. She saved a crucial breakpoint in the 11th game and then broke Keothavong for the second time to claim a well-deserved win. Sania will now face either Japanese Kimik Date-Krumm or Chinese Taipei qualifier Su-Wei Hsieh in the quarterfinals. PTI
