BANGKOK: Indian male boxers endured a mixed day at the Asian Youth Championships, where three advanced to the medal rounds and qualified for the Youth Olympics, while six others lost in the quarter-final stage on Tuesday. Ankit Khatana (60kg), Bhavesh Kattimani Kumar (52kg) and Aman (+91kg) won their respective quarterfinal bouts to enter the semifinals and book a berth in the Youth Olympics, which will take place in the Argentine capital Buenos Aires later this year. While Ankit defeated Korea's Seomho Shin by unanimous decision, Bhavesh got the better of Malaysia's Rasdenal Haikal Muhamad, also a 5-0 verdict. Aman, on the other hand, had to toil hard for his 3-2 triumph over China's Ma Jinyang.
