He has a really big chance. like most , i'm leaning towards Mosley. But if Mayorga was able to have such a close fight with Shane, so will Berto ( i had Mayorga up by a point going in to the 12th) And Mosley has shown struggles against guys with a good jab and that are fast. Shane hasn't fought in a year also , so he's not getting younger. But still, Shane 7-5 for me
