Duran KO1, KO1, KO1. Why? Because his name is Duran. In actuality, Castillo goes the distance but loses a fairly wide decision.
Castillo doesn't last the distance with Duran. Palomino wouldn't have lasted the distance with Duran if it was longer than a 10 rounder. Duran outclasses Castillo, outboxes him, outfights him, and stops him circa 10-11.
Ah. No doubt confusing him with Castillejo, fron Spain, who was fighting at the same time. Keeping track of fighters with similar names (albeit fighting in different weight classes and hailing from different countries) was evidently too much to ask of Foreman. Lol.
