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.
