This is going to be an ugly one.

Oscar does not have the power of Tito, but He has way more speed and skills. He is very pissed off. I saw a video once of a one armed man fighting and he had more defense than Mayorga. Oscar will double Tito in punches landed and due to not having enough power to stop Mayorga early, he will inflict a massive amound of punishment to Mayorga's head. I see a late TKO.
