Martinez pot shots Jr all night to a wide unanimous decision. Jr is too easy to hit for Martinez it will b e a wipe out. Unless Jr puts in he kind of pressure Margarito puts, and Martinez doesn't slip and slide. I just don't see Martinez staying on the ropes taking punishment, he will be moving all night while throwing bombs.
this. Martinez has the unique ability to throw power shots while seemingly moving. It doesn't take long for him to re-set his feet and throw bombs. That's what makes him almost unique right now. Junior has to re-set his feet each and every time he wants to land something big. Martinez is too smart to let Chavez sit in the pocket and load his punches. He just has to dance around him, confuse Jr. It's an easy UD, IF it's in Vegas.
Otherwise, if he'll be fighiting Jr in Texas...he has to knock Jr out. I can see Martinez targeting the body early (first 3 rounds), the go upstairs for the remainder of the fight.
