Birmingham, England-Beijing 2008 Olympic gold medalist Lin Dan won over Danish Joachim Persson in an easy straight set, 21-13 and 21-6. It took only 27 minutes for the Chinese second seed to progress to the semi-final. His next opponent is compatriot Chen Jin. The other men's singles semi-final contenders are Malaysian Lee Chong Wei and Taufik Hidayat of Indonesia.
In the men's doubles, Lee Yong-dae/Shin Baek-cheol will take on fellow countrymen Hwang Ji-man/Han Sang-hoon in the semi-final. Qualifiers Hwang and Han passed fourth seed Zakry Abdul Latif and Tazari of Malaysia with a comfortable win, 21-9, 22-20, in the quarter-final.
Meanwhile, Malaysian coach Rexy Mainaky's dream players Koo Kien Keat and Tan Boon Heong bowed down to Mathias Boe/Carsten Mogensen. The first match went so easy that the Danish pairs win 21-7. Third seed Koo and Tan improved in the second set, but Boe and Mogensen were too good to them that Koo and Tan's attempts were of no use. They lost 7-21, 17-21.
In the mixed doubles, favorite champion Lee Yong-dae and Lee Hyo-jung were out after a 21-13, 18-21, 18-21 defeat by unseeded Chinese Zheng Bo and Ma Jin.
