Koo Kien Keat

Career In 2004, he played in the Thomas Cup with Chew Choon Eng. They gave a strong performance during the second doubles match against Flandy Limpele and Eng Hian of Indonesia in the quarter-finals. However, after the tournament, the Badminton Association of Malaysia decided to partner him with Chan Chong Ming who previously partnered Choon Eng. Later, they won the bronze medal at the 2005 World Championships.

In 2006, Koo's coach, Rexy Mainaky, decided to paired him with the hard-hitting left-hander Tan Boon Heong.

In 2015, Koo announced that he is coming out of retirement to qualify for the 2016 Rio Olympics with Tan before they call it quits for good. They were sponsored by Seri Mutiara Development Sdn Bhd and playing for an independent club. They achieved several breakthroughs this year, winning the Dutch Open and finishing as runners-up at the Thailand Open. They also made it to two Superseries quarterfinals in Australia and Korea.

In 2016, Koo and Tan managed to enter the top 15 of the world rankings. However, due to the new Olympic qualification requirement set by the BWF whereby each country can send two representatives for each event only if they are both in the top 8 of the world rankings in their discipline and if they are not then only the highest ranked representative will contest, Koo and Tan narrowly failed to qualify for the Olympics. By the time the qualification period had ended, the two were ranked world number 14, just one rank behind compatriots Goh V Shem and Tan Wee Kiong who were selected instead and went on to win the silver medal. In November, Koo re-announced his retirement from professional badminton, citing the Hong Kong Open as his last tournament.
