I'd keep the three catchers for now, giving Thole more time to assess if he's worthwhile for the stretch run, and seeing if Barajas will ever wake up. I'd use them as pinch hitters when necessary, and I'd dump Carter (who's basically filling a PH role anyway, so the third catcher can do that, plus Thole is taking grounders at first right? :-P) since he's not really doing that well, and i'm not sure Jerry really trusts him either. Maybe Barajas is really more of a light load type of guy, and we should play him barely 33% of the time for a couple of weeks, he'll wake up, and be healthy and April-May fresh for Sept-OctobeR? In a couple of weeks (well, maybe 10 days depending) you assess if you think Barajas will provide some pop and at least not be an auto-out going forward. See if you can trade him, or just trust him and get Thole the seasoning for a month (back 9/1 presumably). If not, just play Thole, let Barajas go (it's alright, we'll mail him a ring) and be done with it.
