Mexico's Oscar Molina, a Pan Am Games medalist, was eliminated Sunday from the Olympic boxing tournament, losing 8-12 to Canada's Custio Clayton in the welterweight division.
Molina, who had beaten Clayton a few months ago in hemispheric tournament in Ecuador, looked sluggish in the first two rounds and had no time to recover by the time he began to mount an attack.
"I didn't get the job done and I'm not going to blame anybody," the 21-year-old boxer said.
Molina was one of the two boxers representing Mexico in the London 2012 competition.
"I came out a little nervous, I waited too long, he got on top and later he took control of the fight, while I got desperate," the U.S.-born boxer said.
Molina said he and his coach had agreed to pursue an aggressive but intelligent strategy, but he failed to follow through.
"I don't like excuses," Molina said in response to a question about whether his lack of international experience hurt him.
The boxer said he would probably turn pro after the Olympic Games.
"Today, I had my last amateur fight, it's a shame that it went like this, I wanted to make the final," Molina said.
Oscar is the twin brother of American professional boxer Javier Molina, who is also a welterweight.
"We'll never fight, if I have a say in it, I prefer that he do better than me," the Olympian said in response to a question about whether he planned to fight his brother.
Bantamweight Oscar Valdez, who beat India's Shiva Thapa on Saturday, is the other Mexican boxer at the London Games.
Valdez will fight Tajikistan's Anvar Yunusov, who won the bronze medal at the last World Championships, next.
Boxing has produced more Olympic medals - two golds, three silvers and seven bronzes - for Mexico than any other sport.
Mexico, however, has had a dry patch in the sport since lightweight Christian Bejarano won a bronze at the 2000 Sydney Games. EFE
