Summary: Ali has had a solid pro career. He toppled one of the biggest names in the sport – Miguel Cotto – to win his title but the Puerto Rican was on his last legs. He never fought again. And Ali lost his title to Jaimie Munguia in his first defense. He also was stopped by Anthony Young in his most-recent fight.
