Cotto will always bruise fast... His high guard defense. (Even blocked punches smash his gloves against his face) JMM also has somewhat the same problem.
Cotto's face looked worse after BEATING Margo last Dec.This is not unusual for him to look like this winning or losing a fight.
While I thought that Trout clearly won the fight, **** like this means nothing. Some guys bruise up a lot easier than others. You can't use that as indication of what happened in a fight.
