Two-time Olympic medallist PV Sindhu endured yet another first-round exit, but Lakshya Sen and the men’s doubles pair of Satwiksairaj Rankireddy and Chirag Shetty moved into the second round with comfortable victories at the Japan Open here on Wednesday.

The 30-year-old Sindhu, who is a former world champion, went down 15-21, 14-21 to Korea’s Sim Yu Jin in the Super 750 tournament, marking her fifth Round One exit this year.

After a slow start, the Indian World No. 16, who appeared rusty and error-prone and struggled with judgment of length, showed some fight in the first game, but 14th-ranked Yu Jin regained control to claim her first career win over the Indian star.
