WBA super featherweight champion Takashi Uchiyama suffered a stunning defeat at the hands of Panama¡¯s Jezreel Corrales on Wednesday, ending his more than six-year reign atop the division.

Corrales, the interim champion, knocked Uchiyama down three times in Round 2 and referee Robert Hoyle, of the United States, stopped the fight with just one second remaining.

Uchiyama¡¯s streak of successful title defenses came to an end at 11. It was also the first professional loss for Uchiyama (24-1-1), who had retained the belt since he won it from Juan Carlos Salgado in January 2010. For his accomplishment, Uchiyama was given the title of ¡°super champion¡± last year.
