Ko Sung Hyun / Lee Yong Dae was ousted early at the BWF Badminton World Championship 2013 in Guangzhou after loosing to Chinese Taipei pair of Lee Sheng Mu / Tsai Chia Hsin in 3 sets. The top seed Korean pair lost 21-14, 14-21, 19-21 in a 56 minutes battle.
This is indeed a major shock in the men double department as most top pairs thus far didn’t have much problem progressing to the last 8. Malaysia’s top pair of Koo Kien Keat / Tan Boon Heong also made it to the last 8 with a convincing win against unknown Hong Kong pair of Lee Chun Hei / Ng Ka Long. The Malaysian pair won with a score of 21-17, 21-7 in 27 minutes.
