Dieog hurt Csatillo more than Castillo hurt him in the first fight until the knockdowns and even then,we all know what happened.However,in the second fight,with a few changed.JLC well,crushed Corrales(I thought he won every round until the KO) so it's tough. If Diego used some distance,used his jab,mxing in the power shots,I would back him alllll day long but we know he won't do that,he's going to war and that,unfortunately will be his downfall. Castillo,TKO9.
