Vijender Singh defeated Chuluuntumur Tumurkhuyag of Mongolia 27-17 in the quarterfinals of the middle-weight category (75 kg) at the Asian Olympic qualifiers in Astana, Kazakhstan, and booked a place for himself in the London 2012 Olympics. He is the fifth Indian boxer to have secured a London berth after Vikas Krishan (69 kg), Manoj Kumar (64 kg), Jai Bhagwan (60 kg) and rookie Devendro Singh (49kg). Teen sensation Shiva Thapa (56 kg), too, has a chance to book a place for the Games, should he prevail in the quarterfinals on Monday.
