Two-time Olympic medallist PV Sindhu battled her way into the second round of the Indonesia Open with a straight-game win, but it was curtains for former world No. 1 Kidambi Srikanth and Lakshya Sen after they suffered an opening-round exit here on Tuesday. Sindhu was made to work hard by Thailand's Busanan Ongbamrungphan before prevailing 25-23 21-16 in a 51-minute women's singles opening round of the Super 1000 badminton tournament. The former world champion displayed her trademark attacking game to edge a closely fought opening game before carrying the momentum into the second to complete a straight-game win.

The unseeded Indian is now likely to face reigning Olympic champion and world No. 1 An Se-young, whom she had lost to in the quarterfinals last week in Singapore. Sindhu has a dismal 0-9 head to head record against An. However, it was a disappointing day for Srikanth, who bowed out after a 19-21 15-21 defeat to Japan's Yushi Tanaka in the men's singles opening round. Sen, who exited in the quarterfinals of the Singapore Open, bowed out in the opening round here losing 19-21 16-21 to Alwi Farhan of Indonesia. Malvika Bansod too made a first round exit in women's singles. She was outclassed by seventh seed Pornpawee Chochuwong. The Thai shuttler dominated throughout to register a 21-12 21-10 victory.
