PV Sindhu looked awfully out of form as she surrendered without a fight to former world champion Japan's Nozomi Okuhara in the women's singles semi-finals to draw curtains on India's campaign at the Singapore Open here on Saturday.

Sindhu, a Rio Olympics silver medallist, lost 7-21, 11-21 to World No. 3 Okuhara in a lop-sided contest. Sindhu had won the last two times they played each other and overall enjoyed a slight 7-6 advantage in the head-to-head record with Okuhara. The duo had played an epic final at 2017 World Championship that had clocked 110 minutes and is considered one of the best women's singles match in the history of badminton.
