Hamed knocks him out. That performance was a once-in-a-lifetime moment for Pintor, and still in a losing effort (though against the greatest 122 lb fighter ever). Naz probably gets put on his ass at some point, but would get up and eventually catch Pintor with something that - if not fight-ending, then certainly fight-altering and eventually takes him out.
Have to agree with Jake here... Lupe makes a damn good showing of it but he gets KOd here at bantamweight, it would possibly be a different story
