they're both dirty. ortiz shouldn't have done that in the first place. mayweather was ensuring that the headbutt wasn't going to mess up his concentration and game.
he'd rather walk away the winner than possibly lose and have to be even more of a bitch by blaming the headbutt as the cause for a loss. while other's may think he cheated, i call it smart boxing. he definitely taught ortiz a good lesson.
