Bangkok, June 5: Defending champion Saina Nehwal and rising star Arundhati Pantawane advanced to the pre-quarterfinals of Thailand Grand Prix Gold badminton tournament after notching up contrasting wins in women's singles competition on Wednesday.
Saina didn't break much sweat as she prevailed over Shih Han Hung of Chinese Taipei 21-11, 21-16 in a 29-minute match.
The Indian soon reeled off seven straight points to move to 16-7 and then comfortably pocketed the first game.
