The Pirates could have a catching crunch at Altoona in 2012, as both Cabrera and Paulino deserve promotions, but Altoona’s 2011 catcher, Tony Sanchez, does not.

At Bradenton in 2011 Ramon Cabrera hit 0.343, with 25 doubles and 38 walks (as opposed to 29 strike outs). In contrast, his understudy, Carlos Paulino, hit 0.299, with 18 doubles, 18 walks, and 33 strikeouts.

In contrast, Tony Sanchez hit 0.314 with 17 doubles, 28 walks, and 41 strike outs at Bradenton in 2010. Although Sanchez is a good receiver, he has not done so well in throwing out runners. In three minor league seasons he's thrown out 22% of runners attempting to steal. Of course Cabrera only threw out 23%, but Paulino threw out 34%. Sure, sure, you steal on the pitcher, not on the catcher. But the pitchers were not any more adept when Cabrera or Paulino were catching.
