Arreola and fairly easily too. He will walk through Mitchell and with the gun shy way Mitchell is now fighting, he is going to get stopped. He's too scared to throw now and his boxing just isn't very good, so I can see Arreola just taking the fight to him and be landing a lot more than anything coming back. Arreola isn't effective, but I think it is enough to beat the Mitchell's of this world and fairly straightforwardly.
