Davis starting again and Grandal is beginning a rehab assignment. I sort of think that Bart should be getting some more looks, both because he isn't an automatic out so far and because we should presumably get a sense for how he'd do in more frequent playing time before making a decision.
The only caveat would be if this is essentially about giving Davis another week or so of games to try and turn the offensive part of his game around. Grandal has missed a lot of time, so maybe he will have a lengthier rehab to get up to speed, but we might be faced with a decision about trying to get Davis regular ABs.
I still have a high degree of confidence in his bat (probably too much so), but a series of factors make me think that a AAA stint might be the right angle. If he does turn it around quickly, I am not sure how infatuated I would be with losing Bart so quickly. It's been nothing in terms of a real sample size, but he has the pedigree and isn't really all that old, especially for a catcher. I'm not holding my breath for this, but it wouldn't exactly be the strangest thing in the world if he all of a sudden had a mini-breakout to be a competent and solid starting catcher in a new environment. If Davis needs a reset, we could at least do well to try and find out for a solid month or so before moving on.
