Hong Kong will come under intense pressure in the third round of the women's singles at the Badminton world championships in Hyderabad, India, today. World number one Zhou Mi and her two teammates - Wang Chen, finalist at the last worlds and Yip Pui-yin - all progressed yesterday but will need to be at their best if they want to challenge for the title. Zhou cruised past Michelle Chan Ky of New Zealand 21-11, 21-15 in 27 minutes, and will take on Ai Goto of Japan for a place in the quarter-finals. The Japanese overcame 14th seed Wong Mew Choo of Malaysia in three games. Both Wang and Yip needed three games to settle their matches, defeating Porntip Buranaprasertsuk of Thailand 13-21, 21-15, 21-16 and Dutchwoman Jie Yao 17-21, 21-19, 21-19 respectively. Wang will meet Lu Lan, the seventh seed from China today while Yip's opponent is Tine Rasmussen of Denmark, the third seed. 'These are all tough matches,' said Hong Kong coach Chan Chi-choi. 'Zhou will have a slight advantage over Goto as she beat the same opponent in the Macau Open last year, but both Wang and Yip face a daunting task.' Yip lost to the Dane 2-1 when they last met in the All England Championships this year, while Wang suffered the same fate against the improving mainlander. There were mixed results for Hong Kong in the men's singles. Chan Yan-kit reached the third round after defeating Scott Evans of Ireland in three games, but Ng Wei lost to Yu Hsing-hsieh of Taiwan, also in three games. Chan will take on Peter Gade of Denmark. Top-seeded Lee Chong Wei of Malaysia moved into the men's singles third round with an easy 21-11, 21-14 win over Nigerian Ola Fagbemi. 'I don't think I was at my best today, but so far so good,' said world number one Lee, seeking his maiden title at the championships. Chinese world number two Chen Jin overcame India's Parupalli Kashyap 14-21 21-10 21-7, while fourth seed Taufik Hidayat downed Mathieu Lo Ying Ping of France 21-17 21-15.
