Escobar Entering Scary Bad Hitting Territory

Alcides Escobar's complete lack of hitting has been monstrously hurtful to the Royals chances of winning games. Neifi Perez's record -6.8 win probability added (WPA) in 2002 (worst in MLB since 1950, which is as far back as Baseball-Reference's WPA goes) is in jeopardy. After 61 games this year, Escobar is already down to a -3.2; after the same number of games in 2002, Perez was "only" at -2.0. At Escobar's current pace, he would finish the year with an unthinkable -8.5.

If the season ended today, Escobar would already own the fourth worst WPA in Royals history:

The question that has to be answered is how much Escobar has to hit to justify keeping him in the lineup long-term. I don't have an exact answer for that, but I do feel sure he has to do better than this. I'm all for continuing to play him everyday for the rest of the year in the hopes the bat comes around just the slightest, because his defense is a marvel. But so far, that glove is paired with one of the most detrimental bats in history.
