If hatton tries to slug it out he will win by a late stoppage unless castillo cuts him (probably with the head)

If he (hatton) uses the strategy he used against Urango and Maussa he will lose on points

I cant see Hatton willing to risk his body the way corrales did so i'd go with Castillo to win on points, hatton is still young and he does not want to have too many punishing fights and with his weak skin it is a risk
