These two have already fought once with Peralta taking a fairly clear decision victory so i’m not entirely sure why they are rematching. Peralta is a good prospect in the Cruiserweight division but has been rematching a lot of his opponents who he’s already beat convincingly. Karalitzky is a solid domestic cruiserweight but showed in the first fight that he’s not skilled enough to outbox Peralta and doesn’t have the power to turn the fight around.
I think Peralta will use his technical skills to win a eight round decision over Karalitzky.
