Calderon stands him on his head. Solis tried to go toe to toe with Viloria and came out second best, no way Iron Boy gets dragged into that kind of fight. Viloria has been outboxed before and there's no better pure boxer in the little divisions than Calderon.
Calderon is the best pure boxer in the sport today. He doesn't rely exclusively on reflexes but uses skill while winning every second of every round. He easily outpoints Villoria.
I always forget that Calderon is as old as he is. I'd like to see him fight Viloria and Sosa before retring as a truly great fighter.
Well, the plan is to fight Viloria next if Ivan can win his next fight. I think he can beat them both. But this is not Ivan's weight and he is 34y/o already. Not very old for other weight classes but in the small weights is very important. Finito retired at that age. You see when you are 34y/o, 5'0" and 108lbs(105lbs) , you fight against 24 y/o guys that can make the weight at the moment but will end up fighting at 112 or 118lbs.
