An outstanding counter-puncher with a great chin is the template to handle Zamora (see Lujan v Zamora). And there were few that fit the bill better than Castillo. His performance against Pimental was said to be a masterpiece. Zamora was a real front-runner who would gas like a Foreman if those bombs didn't do his opponent in. I see Castillo stopping Zamora similarly to Lujan, in about 10.
