Phillies catching situation

[BritSox]

What's the deal with the setup here? Barajas is listed first on the depth chart, but I've heard that Ruiz might be the starter. Is there likely to be an either/or battle in ST, or will there be some kinda platoon>

A platoon will occur. Ruiz will probably start in the minors but make his way up, and don't forget about Chris Coste.

i think coste will serve as a pinch hitter and he also plays some infield positions i think
