The world No 26 defeated the 13th ranked Japanese player Kenta Nishimoto in straight games of 21-16, 21-18 at the Super 1000 event which offers a total cash prize of US$2 million (RM8.4 million).

Jun Hao, the lone Malaysian representative in the men’s singles after Lee Zii Jia withdrew due to an injury, took 44 minutes to win the match at the Olympic Sports Centre Gymnasium in Changzhou.

Jun Hao, 26, has now beaten the 31-year-old Kenta three times in their five encounters so far.

However, a tough second-round match awaits Jun Hao as he will meet world champion and current world No 1 Kunvalut Vitidsarn of Thailand.

The furthest Jun Hao has reached in the 11 tournaments he had competed this year was the quarter-finals at the Singapore Open in May.

However, their compatriots world No 13 duo Hoo Pang Ron-Cheng Su Yin were knocked out in the first round 15-21, 16-21, by the much lower ranked Chinese pair Gao Jia Xuan-Wu Meng Ying.
