Costa was gassed by middle of 2nd round, and a lot of his shots were blocked or he missed, can see how that would fool people. I re watched the fight and still thought Romero won. Still didn't like how Romero was taking the foot of the pedal, showboating, instead of pushing forward and finishing Costa. The fight was there for him to take it, Costa was looking like he was ready to give up at some point. The judges punished Romero, and I can't really object too much, he should have pressed the issue and learnt from his other fights.
