I think it's going to come down to Chavez's lungs. If he can work more than he did in the Lee fight he should have a chance to wear Martinez down. I've picked Chavez by stoppage but not with insane confidence. The odds are a little too steep for Martinez but I think he should be considered the favorite, though.
Its funny how people are giving Chavez all this credit when he hasnt done a ****in thing his whole career...Oh yeah, I forgot, He beat the great P4P champ..Andy Lee. GTFOH with that Bull****. He's garbage. The only way he wins is if Sergio got old overnite or they rob Sergio on the cards.
