Rising Indian shuttler P V Sindhu pulled off an upset over former world No 1 Shixian Wang of China to storm into the women's singles quarter-finals at the Badminton Asia Championships in Taipei.
The world No 16, the lone Indian woman in the fray in the absence of star compatriot Saina Nehwal, rallied from a game down to win a tense contest 15-21, 21-14, 22-20.
