No doubt Castillo..have to lol over the choice of Zab over Oscar..Mayweather punished Zab once he'd done feeling him out..He only landed one or two good shots on Oscar and many people (the ones not influenced by the BS punch stats), had that fight close. It was the least dominant Mayweather has looked since Castillo.
Castillo, I watched the fight 3 times in one night and had Castillo winning by 2 points twice and 1 point once.
