I voted for Kats by KO. The fight will get stopped late by the corner or the ref. Katsidis has flat out better power than Diaz. He's a vicious body puncher, and he has a workrate to match Diaz.

IMHO, Diaz is incredibly overrated. He's a good fighter, but he's not the future of the division. He's a one trick pony. Diaz is basically Ricky Hatton, but slower, less powerful, and without the great foot work. He does have a decent jab when he decides to use it. He's worked his ass off to get to his point. I respect the guy a ton and you couldn't ask for more humble intelligent guy to represent the sport, but I think he's gone about as far as he can go.
