Hatton will never get a stoppage over Castillo, but if he does get tired trying he can always go into Ruiz mode again. He is a cert to win this on points.
This fight troubles me although I'm finally punting for a Hatton KO late on I am perfectly prepaired for Castillio to win as Hatton's skills seem to have deteriarated. I didn's see his last fight but if it was anything like as horrible to watch as the Colozo fight then it doesn't bode well the art of the jab has been lost.
I think Hatton will just nick it on points. If there's going to be a KO in this fight, it will be Castillo stopping Ricky late if he runs out of gas as he did last time out.
