The thing is, replacing Gallo’s bat should be fairly simple. Replacing his glove much less so. The Yankees might find they’re better off just batting him 8th and letting him secure RF, something Benintendi or Peralta will not be able to do. (Sure, Judge can and probably would move to RF, but is weakening both corner OF poisons defensively really worth the offensive upgrade that 3 or 4 PAs per game would provide?)
As horrific as his offense has been, moving Gallo might not be the improvement the Yankees want. Pitching depth to handle injuries more easily might make more sense…
