kept hearing about this fight during Mayweathers last fight commentary. Watching and this dude really gave him a hard time, good defense, few looping lefts, Mayweather would go into his shoulder roll and he'd bounce off the ropes and get hit with a nice right here and there, Castillo was timing that perfectly, not your run of the muck Mexican brawler, even outlanded him in a few rounds. I'm on round 8 and I've never seen Floyd get outshined on the cards, has Castillo winning by one point. Castillo was moving too much, Floyd couldn't time his offense that easy, even made him switch to southie a few times. Good fight

man this is some bullshit, that forearm smash in the face mayweather uses never gets shit said about it and he was doing it in the middle of the ring for a few seconds, not a mayweather hater but this ref was really fucking shit up this match.
