Four-time world champion M C Mary Kom stormed into the quarter-finals with a thumping first-round triumph on an all-win day for the Indians at the fifth Asian Women's Boxing Championships in Astana, Kazakhstan.

Mary Kom, a Khel Ratna awardee, defeated Filipino Josie Gabeuco 8-1 in a lopsided bout to enter the pin weight (46kg) category quarter-finals.

The other Indian in action, Venlal Duati (48kg) was even more dominant as she out-classed Kyrgyzstan's Rahatova Nazira in just over a minute to march ahead.

The Manipuri was leading 9-0 when the referee awarded the bout to her. Duati too is into the quarter-finals now.

Mary Kom, who won silver in the previous edition of the event in Guwahati, said it was not too tough a bout to start with.

"It wasn't very difficult. I have got a good draw, it shouldn't be too tough but then, I am not taking anybody lightly either. Upsets happen, it's an unpredictable sport but I am confident about myself," Mary Kom said.

Mary Kom took a 3-0 lead in the opening round. She kept widening the gap with every round and didn't let Gabeuco strike a single scoring blow after the lone punch she managed in the second round of the bout.

India [ Images ], which finished third in the previous edition of the event with three gold and two silver medals, have an 11-strong presence this year, comprising former world champions and other international medallists.

In all, 16 countries are participating in the tournament.
