Where the Tampa Bay Rays used John Jaso, Kelly Shoppach and Dioner Navarro in 2010, in 2011 they went with the first two but replaced Navarro with Robinson Chirinos. Jose Lobaton had a cup of coffee too, appearing in 15 games.
In 2010 Jaso had the major share of games with 109, in 2011 he split the duties with Kelly Shoppach. Both appeared in about 90 games.
Together the catchers had a BA of .184, nothing to write home about.
Especially John Jaso's batting average dropped from .263 in 2010 to .224 last season.
Jaso's fielding percentage was identical compared to 2010: .992
I see Jaso be the main guy behind the plate, sharing duties with Kelly Shoppach (if the Rays will excercise the 2012 option of the latter).
Knowing that the Rays normally don't rush their farm hands through the minors, I don't see prospect Stephen Vogt being called up before August/September. But we know that in 2011, Matt Moore played in AA, AAA and was called up in September, while nobody exepcted him to be called up that soon.
I see Stephen Vogt as their main catcher in the near future. Like I said above, I don't expect him to be called up before August/September. But when he keeps putting up the numbers he had last year he may be called up sooner or even make the Opening Day roster.
Furthermore I don't see any competitors for Vogt in the near future. The Rays have a decent catcher in their farm system in Craig Albernaz, but he his moved up and down between AA and AAA. I think he will never make it to the Bigs, unless a void must be filled. Vogt has an advantage that he can also play outfield and first base. So it is up to the Rays where to play him. But IMO they would be better off when they play himbehind home plate.
