Rio Games silver-winner Sindhu defeated world No.18 and 2017 BWF World Junior Championship bronze-medallist Cai Yanyan of China 21-13 17-21 21-14. She will face former world champion Nozomi Okuhara next.
PV Sindhu reached the semi-final of Singapore Open 2019 Super 500 tournament on Friday after surviving a scare against Chinese teenager Cai Yanyan.
Earlier in the day, Saina Nehwal lost her women’s singles quarter-final match to Okuhara.
Notably, Saina had withdrawn from Swiss Open and India Open last month due to a stomach illness and it seemed the ace shuttler hadn’t recovered well from the setback.
