Like Manny Pacquiao before him, Robert Guerrero is in the midst of a possibly historic climb up the scales. The onetime IBF featherweight and super featherweight titlist is now campaigning as a full-fledged welterweight and in his last fight he seized the "interim" WBC belt from previously undefeated Selcuk Aydin in one of the year's better fights.
Meanwhile, Andre Berto is seeking to complete a comeback that was cut short first by injury, then by a positive test for the steroid nandrolone that scuttled his scheduled June 23 rematch against Victor Ortiz. (Note: Guerrero's November 2006 victory over Orlando Salido was converted to a no-contest after Guerrero's own positive steroid test). As a result, Berto's last fight was a fifth round corner retirement over Jan Zaveck to win Zaveck's IBF welterweight title -- in September 2011, or 14 months ago.
Will Guerrero take another big step toward a megafight with the likes of Manny Pacquiao or Floyd Mayweather Jr. or will Berto spoil the party? Their recent CompuBox histories offer the following story lines:
