Malaysia continued to impress, with five of its seven representatives advancing to the quarter-finals, including Aaron Chia-Soh Wooi Yik, who progressed via a walkover.

Hoo Pang Ron-Lai Pei Jing pulled off another notable upset, seeing off Taipei’s world No. 23 Liu Kuang Heng-Hsu Yin Hui after a fiercely contested three-game encounter to record their second consecutive head-to-head victory (21-13, 13-21, 21-17).

In women’s doubles, second seeds Pearly Tan-M. Thinaah held off a late fightback from compatriots Ong Xin Yee-Carmen Ting to prevail in an all-Malaysian clash, sealing a straight-games victory 21-14, 22-20.

However, Aaron Tai-Yap Roy King’s run ended in front of the formidable challenge from Korean top seeds Kim Won Ho-Seo Seung Jae, falling 14-21, 16-21 in 33 minutes.

Chia-Soh booked their place in the quarter-finals without taking to the court, receiving a walkover following the withdrawal of Thailand’s Peeratchai Sukphun-Pakkapon Teeraratsakul.

Man Wei Chong-Tee Kai Wun handled the pressure in the opening game to snatch 25-23 before pulling away in the second to dispatch Japan’s eighth seeds Takuro Hoki-Yugo Kobayashi 21-14.

The victory levelled their head-to-head record at 2-2.

Sixth seeds Goh Sze Fei-Nur Izzuddin Rumsani rounded off the day with a hard-fought three-game victory, surviving a spirited challenge from Denmark’s Daniel Lundgaard-Mads Vestergaard to outlast 21-6, 14-21, 21-18.

The victory avenged their consecutive defeats at the Malaysia Masters in May and the China Open in July.

With Chia-Soh set to face Man-Tee in an all-Malaysian quarter-final showdown, Malaysia are guaranteed a men’s doubles representative in the last four.
