I honestly think there is going to be a rematch regardless of who wins. To answer the question I think it might be the only way he can win, being I don't see Martinez stopping Jr.
On a side note why did Kellerman bring up GGG while pumping up Sergio's **** for fighting Maklin & Barker??? Last time I checked Sergio didn't fight any of his manditory fights... No Pirog, No Rubio, No Golovkin.
Arums passed 3 PPV have been stained with robberies. Pac-MarqueZ 3 Rios Abril Bradley Pacquiao... I'd put my money on the tradition to continue, the good thing for Martinez is if he doesn't KO JR... he is getting KO'ed himself... **** ain't going to the cards unless Martinez starts running around the ring in survival mode... but I doubt it.. he'll get tired sooner or later and JR will beast on him.
Abril arguably won 11 rounds in his fight and Rios got the decision. Martinez cannot get the decision if it goes the distance.
