Mayweather all day long. Apart from 1 nice bit of work from Castillo with about 30sec go when Floyd was against ropes, that round was basically hit and not get hit from Mayweather. Good movement with lots of connecting jabs, controlled the round almost the whole time. Imo you are not scoring the round as a 3 minute slice of action if you give that round to Castillo. I totally disagree with Lederman scoring the round to Castillo.
