Prannoy, who emerged runner-up to Sai Praneeth B in the last Junior Nationals, shocked top seed Ajay Jayaram in the first round before outwitting Srikanth K 17-21, 21-13, 21-16 to book a spot in the quarterfinals at the Karnataka Badminton Association courts.

Having defeated Ajay 21-18, 22-20 in the morning session, Prannoy appeared full of confidence against the unheralded Srikanth of Andhra Pradesh. Mixing smashes with occasional net play, the 18-year-old Prannoy kicked himself to a 14-10 lead and just when he appeared to race away, Srikanth staged a remarkable recovery to claim the first game.

The loss of the opening game seemed to spur Prannoy as he had Srikanth running for cover in a completely lop-sided second before completing the comeback job with a tenacious display in the decider.

Among the upsets in the opening round, Railways’ P Vinay Kumar Reddy accounted for fourth seed Mohit Kamat, Abhimanyu Singh felled third-seeded Tanishak K while Ajit Wijetilak put it past eighth seed Nanda Gopal K. However, only Abhimanyu was able to make it to the last-eight stage.
