Never always had the WBC strap in each divinson, but won the IBF from Zab after he kept the belt since Baldo couldn't pay the fees
I think he was to focused on winning titles progressivley in higher weight classes, a feat equaly as impressive as holding unification status in just one.
Beat Diego, who was a beltholder. Beat Zab and then Baldo, who were both beltholders. In theory, Mayweather has unified titles in two divisions. ****in sanctioning bodies...
Have been watching his fights back at 130lbs...could have held every title if he wanted. Amazingly dominant.
