Emotional Manny Pacquiao feels he has let country down following defeat to Juan Manuel Marquez I have long asked you son, it is time to retire because you started boxing at such a young age. I always pray that he will stop. I asked God to tell my son to stop," she said. She said she was alarmed by her son's knock-out at the hands of Marquez in the sixth round of their non-title fight Saturday night local time in Las Vegas. The loss stunned a huge Philippine audience watching the fight live on television on Sunday. I was shocked yesterday. The way he suddenly fell," said Pacquiao's mother, who added that, like in previous bouts, she had only watched a recording because she could not bear to watch her son's fights live. But while moved by the women's entreaties, Pacquiao remained non-committal on calls for his retirement. "I don't want to hurt my family and the people who support them," was all he would say about his future plans. I just got overconfident in this fight. That is part of the game - sometimes you win, sometimes you lose. Pacquiao said immediately after the loss that he intends to fight again. The Filipino fighter who has won world titles in an unprecedented eight weight divisions has extended his boxing success into election to parliament, a career in show business and commercial endorsements. But there have been questions about Pacquiao's focus on his boxing in recent years as he has had to deal with his duties as a congressman, host of a television game show and as pitchman for various products. In the past year he has also become a Bible preacher, though he insists his religion has not dulled his killer instinct in the ring.
