It's difficult to say. I think Bob Baker, Embrel Davidson and Alejandro Lavorante are probably in the running though.
Bob Baker definitely "Light heavyweight champion Archie Moore said today he "felt wonderful" as he carried 190 1/4 pounds - the heaviest fighting weight of his career - to a slashing non-title victory last night over Bob Baker. Moore boxed Baker through the first three rounds and there were a few scattered boos before the champion leaped to the attack seriously in the 4th, when he first brought blood from Baker's nose and mouth. Baker, retreating throughout the fight, brought Archie to sudden attention with a pair of hard rights to the nose in the 6th and Moore responded with an angry assault that opened cuts over Baker's eyes. Referee Petey Sarron stopped the Miamai Beach Auditorium battle at 2:08 of the 9th round with Baker reeling under a savage attack by Moore." -Associated Press Miami Promoter Joe Schaefer stated after the bout that he would be guaranteeing Rocky Marciano $250,000 to fight Moore in Miami.
