KUALA LUMPUR: National women's singles ace Goh Jin Wei provided the biggest shock of the day when she stunned world No.5 Akane Yamaguchi to reach the last 16 of the Perodua Malaysian Masters on Wednesday (Jan 16).
The 18-year-old won 21-14, 21-12 in 33 minutes for her first victory over the Japanese opponent in four meetings.
Also through to the second round was Lee Zii Jia in the men's singles, who defeated Tanongsak Saensomboonsuk 14-21, 21-18, 21-10.
However, his hopes of facing world No.1 Kento Momota went up in smoke when the Japanese superstar suffered a shocking first round defeat to compatriot Kenta Nishimoto.
Nishimoto, last year's runner-up, sent the top seed packing after prevailing 21-15, 14-21, 22-20 in a pulsating 74-minute affair.
Malaysia also impressed in the men's doubles with country's top three pairs Goh V Shem-Tan Wee Kiong, Aaron Chia-Soh Wooi Yik and Ong Yew Sin-Teo Ee Yi all safely cleared their opening hurdles.
V Shem-Wee Kiong fended off spirited challenge from China's Di Zijian-Wang Chang 21-14, 19-21, 21-9 to stay on course for a back-to-back victory following their Thailand Masters success last week.
They will face Hendra Setiawan-Mohammad Ahsan of Indonesia for a place in the last eight.
Aaron-Wooi Yik set up a last 16 clash against defending champions Fajar Alfian-Muhammad Rian Ardianto after outclassing England's Marcus Ellis-Chris Langridge of England 21-19, 21-12.
It was a sweet revenge for Aaron-Wooi Yik over the Rio Olympics bronze medallist Ellis-Langridge having being pipped to the SaarLorLux Open title in Germany last October.
Yew Sin-Ee Yi are also through after a solid 21-14, 21- 14 win over eighth seeds Liao Min-chun-Su Ching-heng of Taiwan.
