He didn't gain as much before this last fight. Anyways I can see Mayweather beating Hatton on the inside or outside. Hatton holds when he gets in which might cause Mayweather the same problems Castillo did. However I believe with a good ref Hatton will not or should not be able to hold that much against Mayweather or suffer penalties as well Mayweather shouldn't be allowed to push off or use his elbows.
