Koo Kien Keat
Nearing the Doha Asian Games in 2006, Rexy Mainaky (the Malaysian doubles coach) decided to split them up and partner Tan Boon Heong with Koo Kien Keat instead. This move, nevertheless, proved to be spot-on as this pair went on to become the Asian Games champion, winning the gold medal in their maiden outing by defeating the then Chinese world champions, Cai Yun and Fu Haifeng, in the quarterfinals, Indonesia's Markis Kido and Hendra Setiawan in the semifinals, and finally Luluk Hadiyanto and Alvent Yulianto, also from Indonesia, in the finals. They are the youngest men's doubles to win gold medal at Asian Games at the age of 21 and 19 respectively.
