Kom stars on historic day - London 2012 - Boxing
Indian Mary Kom entered the London 2012 Olympic Games in sensational style on an historic day for women's Boxing at ExCeL.
Kom's bout was as action-packed as anything that had come before, as the 29-year-old flung hooks at the head of her upright opponent, roared on by a sizeable Indian contingent in the 10,000-capacity crowd.
Kom was emotional afterwards as she reflected on her long journey to the Games and the fifth birthdays of her twin sons, Rengpa and Nainai.
In front of global press and camera crews, Kom said: 'Every athlete wants to go to an Olympic Games and for 12 years I have been waiting and waiting, asking when it (women's Boxing) will be included.
'It is very special. I am crying because it is my twins' fifth birthdays. It is emotional because I cannot be with them to celebrate their birthdays, but I am here at an Olympics, and I am fighting and winning.'
Kom, whose five world titles all came in the lighter 46kg division, dominated Michalczuk despite the obvious size and weight discrepancy, to move through to Monday's quarter-finals where she will fight for a medal.
If successful against Tunisia's Maroua Rahali, Kom could set up a repeat bout against Great Britain's Nicola Adams in the semi-finals. Adams begins her quest against Bulgaria's Stoyka Petrova on Monday.
In a session of well-matched and generally exciting fights, Elena Savelyeva had had the honour of being the first winner of an Olympic Games women's bout, beating DPR Korea's Hye Song Kim.
The 28-year-old former world champion said she was 'happy' to have written her name in the record books after her impressive 12-9 victory.
Savelyeva said: 'I feel proud to make history and it was amazing. I had most of the same feelings, but maybe I was a little bit more nervous than normal.'
Meanwhile, in the men's Heavy weight division, Ukrainian world champion Oleksandr Usyk won a powerful battle with old foe Artur Beterbiev of Russia 17-13, while Bulgaria's Tervel Pulev was a 13-10 winner over Yamil Peralta of Argentina. In the Bantam Weight class, Luke Campbell claimed a one-point win over Detelin Dalakliev as he became the first Great Britain boxer to guarantee a medal with a 16-15 quarter-final win.
