Choong Hon Jian-Haikal Nazri battled for close to an hour before defeating their national team-mates and recent Japan Open champions Goh Sze Fei-Nur Izzuddin 13-21, 21-16, 21-16 to advance at the Korea Open.

Fresh off their biggest career triumph in Yokohama on Sunday, Goh-Haikal made the journey for this Super 500 event in Seoul with barely any rest.

The world number 12 pair still gave it their best shot against Choong-Haikal, but the freshness of their team-mates told in the end.

Choong-Haikal will go on to face Choi Sol-gyu-Heo Kwang-hee in the men's doubles second round, and they would have surely taken some lessons from Goh-Izzuddin on how to navigate past South Korean opponents.

Goh-Izzuddin, had last Sunday at the Japan Open final, defeated Kang Min-hyuk-Seo Seung-jae who are reigning world champions and top seeds in this event.

Tan Kian Meng-Lai Pei Jing were the other doubles pair who secured their spot in the next round after the mixed doubles duo overcame Americans Presley Smith-Allison Lee in straight games.

Tan-Lai will go on to face a Chinese Taipei pair for a place in the quarter-finals.

Leong Jun Hao, who was Malaysia’s only representative in the men’s singles, crashed out after a 20-22, 14-21 defeat against Japanese Takuma Obayashi.
