World No. 1 Saina Nehwal started her campaign with a hard-fought win, while P V Sindhu too continued her rampaging run, but it was curtains for shuttler Parupalli Kashyap at the Badminton Asia Championship in Wuhan, China today. Olympic bronze-medallist, Saina, who got a bye and a walkover in the first two rounds, won over Japan's Nozomi Okuhara in a women's singles match. Saina will next take on fifth seed Tzu Ying Tai of Chinese Taipei. Eighth seed Sindhu, a two-time bronze winner at the World Championships, set up a clash with top seed Li Xuerui of China in the quarterfinals after brushing aside Macau's Teng Iok. However, Kashyap, who had played a long match against Chinese Taipei's Jen HaoHsu, could not continue his winning run as his gallant fight ended with a 23-21, 17-21, 8-21 loss to seventh seed Zhengming Wang of China.
