THe problem with Castillo in that fight, and reason why I don't think he won is because Mayweather landed the sharper more effective blows more often. Castillo did catch him more times than anybody else has, but he landed a lot of his punches while they were clinched which for me shouldn't count. There were a few times where I felt Castillo was just punching to land anything instead of using good, technically flawless punches.
