After successful performances in her 2012 campaign, former world champion Chantall "La Fiera" Martinez (18-5, 7KOs) of Panama has been placed in the number five position by the International Boxing Federation, as she continues to push for a crack at the female super bantamweight championship - currently held by Katy Wilson Castillo of the Dominican Republic. Martinez was beaten by Mexican superstar Jackie Nava, the WBA's champion, last January, but came back with three solid victories to get herself back in the title picture.
