As Doug Gray pointed out, Edwin Encarnacion is hitting 0.359/0.375/0.590 with 2 HR's in 39 AB's since arriving in AAA. Sounds to me like he's ready to come back...starting Juan Castro at 3B every night certainly isn't getting the Reds anywhere fast, and at this point the Reds are so far behind that they need to put their best potential offense on the field each night, defense be damned.
Update: Eddie's back and starting, as it should be. He earned it. I did support sending him down to get him a jump start and to put a bit of fear into him, but at this point the Reds need to rally around the kid and help him be what he can be.
Hope Hamilton's tummyache gets better soon.
