I would think it would be hard to get comfortable behind the plate when:
1. You're playing once or twice a week.
2. You only get to catch two of the starters.
I'm sure Latos would feel more comfortable with Mes if he got to pitch to Mes.
I'm sure Cueto would feel more comfortable with Mes if he got to pitch to Mes.
Dude is going to get any better sitting on the bench.
If the Reds are truely "all in" than trading Mes and Hamilton for another upgrade in the rotation, or a replacement for Ludwick would seem like the thing to do.
