In the following Thomas Cup, both pairs are the mainstay players.
In the first set, Indonesia's Karnando/Martin was in poor form, there were many unnecessary mistakes, and in the case of a backward start, Karnando/Martin seemed to have given up the first set, and the Japanese men's doubles Nakamura/Onodera easily won the first set 21:7, leading 1:0. In the second set, Indonesia World Youth Champion Karnando/Martin stepped up their counter-attack and successfully won a set at 21:13, with the two sides drawing 1:1.
