London (8/11) - All world number ones advance to Yonex BWF World Championship semi-finals. In the men's singles semi-final, top seed Lee Chong Wei is challenged by Guatemala's unseede Kevin Cordon. Cordon, who is unexpected to reach the quarter-finals, beat Spanish Pablo Avian 21-19, 19-21, and 21-17 in the third round. Earlier, Cordon has crushed China's fifth seed Chen Long in the first round.
Meanwhile, in the bottom half, 2008 Olympic champion and three-time world champion Lin Dan of China conquered South Korean Lee Hyun-il in straight sets 21-16 and 21-13 to book the quarter-final clash with Japanese Sho Sasaki. If Lin Dan beat Sasaki, he might face either the only European men's singles player left, Peter Gade, or Vietnam's Nguyen Tien Minh.
“Hyun-il is a patient and steady player. He is certainly playing better after coming out of retirement. But I am happy that I stayed calm and did my job well,” said Lin Dan.
“I feel good about my game so far and I will give my best.”
Before meeting seventh-seeded Cheng Shao Chieh in the last eight, the women's singles number one Wang Shixian of China subdued Thailand's Porntip Buranaprasertsuk 21-7 and 21-11. Shixian's compatriots, Wang Yihan and Wang Xin, also successfully reach the quarter-finals. Second-seeded Yihan will play French Pi Hongyan while third-seeded Wang Xin will face Indian Saina Nehwal.
In the men's doubles, China's Cai Yun and Fu Haifeng won a three-set match against Japanese Naoji Kawamae and Shoji Sato 21-17, 15-21, and 21-14 to meet Mads Conrad-Petersen and Jonas Rasmussen of Denmark in the last four. Their juniors, Shen Ye and Hong Wei, also advances to the semi-final to face world number three Lee Yong-dae and Jung Jae-sung who defeated Hiroyuki Endo and Kenichi Hayakawa easily 21-14 and 21-5.
China places two women's doubles pairs in the last eight, and so does Indonesia while Japan has three pairs. World number one pair from China, Wang Xiaoli/Yu Yang, will meet Japanese Shizuka Matsuo/Mami Naito.
In the mixed doubles, top seeds Zhang Nan and Zhao Yunlei cruise to the quarter-final with a 21-13, 21-18 win over German Michael Fuchs and Birgit Michels. Next they play Taiwanese pairs.
