Wang Yihan secured her place in the semi-finals of the Malaysia Open after upsetting world number one Carolina Marin 21-13, 21-15 at the Malawati Stadium on Friday.
The 2011 world champion took the lead early in the first game and never looked back from there, dominating her Spanish opponent throughout the 38-minute encounter.
The Chinese sixth seed will take on Thailand’s Ratchanok Intanon for a spot in Sunday’s final, after the fourth seed made short work of her opponent, PV Sindhu.
The 21-year-old from Bangkok needed only 29 minutes to book her place in the last four with a 21-7, 21-8 win over the unseeded Indian shuttler.
The other semi-final will be contested by third seed Saina Nehwal and the unseeded shuttler from Chinese Taipei, Tai Tzu Ying.
Former world number one Nehwal, seeded third in Malaysia this week, had to call on all her resolve against another Indonesian, Porntip Buranaprasertsuk, eventually winning 19-21, 21-14, 21-14.
Tzu Ying was responsible for sending another one of the Chinese contingent, fifth seed Wang Shixian packing, winning 21-14, 21-14 after spending 37 minutes on court with the world number five.
