Six-time world champion MC Mary Kom (51kg) powered into the Olympic Games' pre-quarterfinals after staving off a stiff challenge from Dominican Republic's Miguelina Hernandez Garcia in the opening round.

The 38-year-old, who is a 2012 Olympic bronze-medallist, prevailed 4-1 against a rival who is 15 years her junior and a Pan American Games bronze-medallist. In a bout that was exciting from start to finish, Mary Kom displayed some brilliant tactics to overcome the spirited fight that Garcia put up.
