Arguello late KO but wouldn't be 1sided, Castillo would put some hurt on him. I see a Corrales-Castillo 1 type fight with Arguello doing better than Corrales
I think Castillo could give him a hard fight just with his toughness and relentlessness (like Mancini did), but Arguello's skill and pinpoint punching would see him through to a win. Arguello by fair decision.
Arguello would knock him out in about 8 rounds I think. Would be fairly back and forth before the denouement.
Hardly a controversial pick there Bill. It's near impossible to imagine Castillo lasting ten rounds with Arguello given his style. The Corrales fight should alert everyone as to that.
