Certainly not his fault. Dombrowski's fault. But since there's no other way to upgrade the spot until Rojas (not that he's an upgrade at the plate) or closer to trade deadline (by which point they might not be buying) seems like it's past time to bring Kemp back up or just actually play Marsh every day finally. And Crawford too.
What's ironic is they could really use Weston Wilson. He's actually doing pretty well, but even if he wasn't, having a AAAA guy to fill the spot lets you keep giving Kemp regular ABs in Allentown. Though I suppose if they really wanted that they could also have kept Moore instead of Reyes.
