xISO uses statcast data (EV, launch angle) to determine probabilities for expected extra base hits. Since Paredes overperforms his xISO, there is an assumption on my part that he is going to fall down to earth with his baseball card numbers and it could get kind of ugly. If he's not a flyball hitter, that Monster is going to turn his HRs into 2B's which will greatly reduce his SLG. For a guy without a lot of extra base hits to begin with, less than Bryan De La Cruz, it's not going to be a big boon for him to move to a stadium like Fenway. Only 26 of his career 72 HR would have been a HR at BAL.
