I really don't see any reason to replace him right now. As long as he can still play quality defense behind the plate, he is too valuable to let walk just because he only hits 1 out of 4. It's not like there is a lineup of quality every day catchers available. I don't see why people are trying to rush him out the door, even if he is losing his offensive game, he still ranks as one of the best offensive cathcers.
