Angus Ng Ka Long and Son Wan Ho joined the early exodus of seeds at the Singapore Open as both men were eliminated in Thursday’s second round.
Viktor Axelsen and Chou Tien Chen were first-round casualties on Wednesday, and now seventh seed Long and fourth seed Son have joined them in exiting the tournament prior to the business end.
Long was up against unseeded South Korean Lee Dong Keun, and despite winning the first game comfortably, he ultimately went down 14-21, 21-12, 21-18.
Son, meanwhile, faced Indonesia’s Jonatan Christie, and found himself on the receiving end of a 21-15, 21-18 defeat.
Only two seeds are left standing heading into the quarter-finals of the men’s draw.
China’s Shi Yuqi, the fifth seed, advanced after beating Pablo Abian 21-10, 21-16, while eighth seed Tanongsak Saensomboonsuk of Thailand is also still alive after securing a 21-17, 23-21 victory over Hu Yun.
Two Indian shuttlers, B Sai Praneeth and Srikanth Kidambi, are also still alive.
The only upset in the women’s draw was American Beiwen Zhang’s 21-10, 25-23 victory over eighth seed He Bingjiao.
Top seed Tai Tzu Ying advanced to the last eight after thrashing Chiang Mei Hui 21-11, 21-8, while second seed Sung Ji Hyun was a 21-11, 21-16 winner over Pai Yu Po.
Carolina Marin, PV Sindhu, Akane Yamaguchi and Sun Yu all booked their spots in the quarter-finals as well.
