The world No 4 beat their unranked opponents Rinov Rivaldy-Lisa Ayu Kusumawati 21-17, 21-17 in straight games in a match that lasted 36 minutes.

The husband-wife pair, who lost in the Malaysia Open semi-final last week, began the first game at a sluggish pace but picked up in the second game to defeat the Indonesians, who were partnering for the first time.

In another mixed doubles match, world No 34 Wong Tien Ci-Lim Chiew Sien fell to the unranked Japanese pair of Yuta Watanabe-Maya Taguchi in their opener.

Watanabe-Taguchi took only 36 minutes to win 21-17, 21-15 as the Malaysian pair made numerous unforced errors.

World No 28 Leong Jun Hao meanwhile said he was over the moon after overcoming China’s world No 6 Li Shi Feng 18-21, 21-17, 21-17 to advance to the second round yesterday.

Jun Hao said his patient game play against the reigning Asian Games gold medalist had paid off, and that he was now focusing on his recovery ahead of tomorrow’s tie against China’s world No 21 Weng Hong Yang.

“It (the win against Shi Feng) means a lot to me because I’ve never won even one game against him before,” he said in an audio recording shared to the media by the Badminton World Federation.

“He’s a tough opponent physically… I just played with what I have and did my best,” Jun Hao said.

Meanwhile, top mixed doubles pair Chen Tang Jie-Toh Ee Wei said they were delighted to have achieved the highest ranking of their careers after climbing to world No 3 yesterday.

“We are proud to achieve (such a high ranking), but we will stay humble and hungry to win,” Tang Jie said in a Bernama report.
