Bit of a tossup, difficult to predict. Will go with Pacquiao by decision, a class above, though its a big leap. I don't think Martinez is disciplined enough nor skillful enough to avoid being out punched in exchanges. I can't see him stopping Manny as he isn't aggressive enough and doesn't have the one punch KO power you need to stop someone with the conditioning and footwork of Pacquiao. I might give Mayweather a better chance than Martinez.
