Olympics: Mary Kom Keeps Alive India's Medal Hopes, Hockey Team Crushed

Both of them traded punches for a while but it was clear that the diminutive Indian was well ahead. With quick feet and quick hands, Mary Kom surged ahead into the lead, taking the round 7-3.

With both boxers tiring in the fourth round, the Indian tried to stay away from the reach of her opponent, who had to reduce a five-point deficit.

Karolina fought hard for a comeback but the Indian was too good for her. Time running-out, the Pole caught Mary Kom a couple of times but could only draw the final round 4-4.

At the Riverbank Arena, the eight-time Olympic champions, who returned to the Games after missing out on Beijing in 2008, were outpaced by the South Koreans.

The South Koreans, who had suffered a 1-2 loss to lowly-ranked Belgium in their last match, played with vengeance. They were impeccable from their penalty corners, converting three of the five chances that came their way. Hyun Woo Nam (60th, 70th) struck twice while Jong Hyun Jang (6th) and Lee Seung (68th) got goals apiece.
