New Delhi: Teen sensation Shiva Thapa (56kg) inched closer to Olympic qualification but London dreams ended for Commonwealth Games gold medallist Suranjoy Singh (52kg) who lost in the second round of the Asian Olympic Boxing Qualifiers in Astana, Kazakhstan, on Saturday.

Suranjoy was out-punched 10-30 by Mongolia’s Tugstsogt Nyambayar, who was his nemesis in the 2009 and 2011 World Championships, as well.

The 25-year-old Manipuri thus became the first Indian to bow out of the event, which will decide the last 25 slots for the London Games from the Asian region.

“It was not his day. Once he was 2-6 down in the opening round, he became overtly aggressive and the Mongolian guy took advantage of that,” national coach Gurbax Singh Sandhu said from Astana.

Down 6-15 in the second round, Suranjoy took quite a hammering in the final three minutes, conceding 15 points to Nyambayar.

But Shiva ensured that India had something to cheer about. Competing in only his second senior international event, the Youth Olympics silver medallist notched up a comprehensive win in his opening bout.

The 18-year-old beat Mohammad Khaiber Nooristani of Afghanistan 14-7 after getting a first-round bye in bantamweight division.

He now has a tough bout as he will be up against 2004 Olympic silver medallist Worapoj Petchkoom of Thailand on Monday.

The 30-year-old Petchkoom is a bantamweight veteran, having won a bronze medal at the 2006 Doha Asian Games.
