The in-form HS Prannoy progressed to the second round with a fine show but PV Sindhu and Kidambi Srikanth's inconsistent run continued, as they made opening round exits in the Korea Open Super 500 tournament here on Wednesday.
The fifth-seeded Prannoy, the only Indian singles player in the elite top 10, registered a 21-13, 21-17 win over Belgium's Julien Carraggi. The 31-year-old will face either Lee Yun Gyu or Lee Cheuk Yiu next.
Sindhu, who slipped to world No. 17 this week, lost to 32-year-old world No. 22 Pai Yu-Po of Taiwan 18-21, 21-10, 13-21 in the women's singles opening round. The contest lasted 58 minutes.
Srikanth, on the other hand, squandered a match point advantage in the second game to go down 21-12, 22-24, 17-21 to former world No. 1 Kento Momota from Japan.
Priyanshu Rajawat, however, advanced to the second round with a 21-15, 21-19 win over local player Choi Ji Hoon and set up a clash with top seed Kodai Naraoka of Japan.
