nothing definitive happened in that round. mayweather landed double the punches, jabs to the body and head, but had no power on any of them. castillo landed about 5 power punches...which connected but caused no harm. floyd showed great footwork and ring generalship while castillo chased him around the ring the best he could and landed a few times when he was able to get floyd's back on the ropes. floyd grabbed or pushed off while castillo tried hard to get some infighting done.

i guess it depends on what you like in a fight.
do you watch boxing to see punches or pirouettes? i know what i like.
