Judge is playing CF for the most part(A premium position). It is closer than you would think. But I see a scenario where judge breaks his record if he gets red hot, and than there is nothing witt can do to top that including hitting 400+ between now and the end of the season. But in a normal year or if he was in the NL the answer would be the MVP, although I might be fair on Ohtani there. but it would be close with ohtani.
Here is the problem Judge lead baseball in WAR, Homer, RBIS, OBP, Slugging, OPS. Witt in any other year would have a good shot, this year not so much. Doesn't change the fact Witt is having a great year, and might lead the royals to the playoffs.
In the meantime we will see if the mets can continue to help the royals with the twins. All is just my opinion of course.
