That kind of makes me wonder about it too..... martinez is known for his stamina, oscar is the one who is known to fade... he seems to have a lot of nervous energy and tightness in the opening rounds. I guess it depends on how good Martinez's movement is and if he can make oscar chase him and land counters, hes good but I dont know if hes that good. Oscar does better with guys that will fight him and trade like vargas. Martinez is really open with his hands though and Oscar has the speed to catch him. Im not sure on this one, think it depends if oscar catches him enough.
Hard to say at 154, The Oscar that stopped Vargas probably takes a decision over Sergio. At 160 ? I give Oscar almost no chance.
