BWF profile

Koo Kien KeatAMN (Chinese:古健傑;Pe̍h-ōe-jī:Kó͘ Kiān-kia̍t; born 18 September 1985) is a Malaysian former professionalbadminton player. He succeeded in both men's and mixed doubles and in his partnership withTan Boon Heong he reached a career high ranking of world number 1.^[2]

In 2004, he played in theThomas Cup withChew Choon Eng. They gave a strong performance during the second doubles match againstFlandy Limpele andEng Hian ofIndonesia in the quarter-finals. However, after thetournament, theBadminton Association of Malaysia decided to partner him withChan Chong Ming who previously partnered Choon Eng. Later, they won the bronze medal at the2005 World Championships.

In 2006, Koo's coach,Rexy Mainaky, decided to paired him with the hard-hitting left-handerTan Boon Heong.^[2] Together, they won the gold medal at the2006 Doha Asian Games as an unseeded pair. En route to the finals, they defeated several top pairs includingMarkis Kido andHendra Setiawan of Indonesia. They are the youngest ever men's doubles pair to win an Asian Games gold medal at the age of 22 and 19 respectively. 2007 was the best year for Koo and Tan. They won severalSuperseries tournaments and climbed to the top of world rankings. They also won their firstAll England Superseries title after beating Chinese pair,Cai Yun andFu Haifeng in straight games.

In 2009, the two won the bronze medal at the2009 World Championships. At the 2010 BWF World Championships, the pair entered the semifinals after beating Korean rivalsJung Jae-sung andLee Yong-dae. In the semifinals they defeated China'sGuo Zhendong andXu Chen 21-14, 21-18. Tan and Koo became the first Malaysian pair to enter a World Championship final in 13 years. In the finals, they played China'sCai Yun andFu Haifeng but lost 21-18, 18-21, 14-21.

In 2010, they won theirfirst title of the year in their home, Malaysia, as the world number 1 pair. They came in seeded number 1 in theAll England Open but lost in the first round to Denmark former world championsLars Paaske andJonas Rasmussen.

In the2010 BWF World Championships, they beat the young Chinese pair ofChai Biao andZhang Nan in the quarter-finals and later their arch rivals, the South Koreans Jung Jae-sung and Lee Yong-dae, in 3 sets to reach the semi-finals. After that, they beat another Chinese pair of Guo Zhendong and Xu Chen to reach their first ever finals in World Championship. The only other Malaysian pair to reach that far before them wereCheah Soon Kit andYap Kim Hock.

At the2011 All England Open, Koo and Tan defeated 2008 Olympic champions Markis Kido and Hendra Setiawan in the quarterfinals. They then defeated World championsCai Yun andFu Haifeng 21-11, 23-21. They lost to the Danes and then world number 1Mathias Boe andCarsten Mogensen 21-15, 18-21, 18-21.

In 2012, they competed at the2012 London Olympics, reaching the semi-finals losing to the eventual gold medalists, and then losing in the bronze medal match to the Koreans.^[1] In 2013, they suffered a series of early round exits in 2013 and a three-year major title drought but managed to remain in the top 10 of the world rankings. In 2014, Koo parted with theBadminton Association of Malaysia and became a coach for the Granular Club of Thailand in early 2014. In August that year, Koo returned to play his last tournament with Tan at the2014 BWF World Championships in Copenhagen, Denmark. Their supposedly last match together was in the third round where they lost to a Chinese Taipei pair with a score of 19-21 in the deciding game.^[3]

In 2015, Koo announced that he is coming out of retirement to qualify for the2016 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 theDutch Open and finishing as runners-up at theThailand Open. They also made it to two Superseries quarterfinals inAustralia andKorea.

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 theBWF 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 compatriotsGoh V Shem andTan 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 theHong Kong Open as his last tournament.
