No, his bat doesn't justify a pitch-calling rating that low. I have used two catchers with 48 pitch calling ratings, but they were both HoF caliber hitters. You could probably use him as a 25th man to come off the bench and pinch hit, but that is all that he is good for and you could actually find a better option for that role at league minimum on the waiver wire, in the rule 5 draft, or in free agency.
