MUMBAI, Dec. 23 -- The big match temperament of third seed Tiann Castellino was on display against top seed Anvisha Ghorpade, as she scored an upset win in three games to lift the Girls U-15 singles title in Yonex-Sunrise Gautam Thakkar Memorial Junior State Badminton Championships, sponsored by Cricket for Care at the Bombay Gymkhana late on Sunday. The young shuttlers were cheered on by a star-studded crowd, among them close friends of the late Gauram Thakkar, Sunil Gavaskar and Aparna Popat, to name a few. The event was promoted by Badminton Gurukul. After losing the first game 17-21,Tiann made a strong comeback in the closely-fought second.

Boys U-15 top seed Aditya Padwal also had a scare against Chandranshu Gundle when he dropped the second game, but that proved a temporary setback as he collected his wits to win the decider and close out the match 21-17, 15-21, 21-15.
