There's a blog post up at BA, looking at CS% for catching prospects, with Taylor Teagarden and Max Ramirez both among those that they have the numbers up on.
They also compare the catchers who made their "mid-season top 10" catcher rankings, and Teagarden is the only catcher in the top 10 who is better than his league average in throwing out baserunners. He also, though, ranked only 10th in the top 10, although one would think that he'd be higher after continuing to mash in AA. Max Ramirez, meanwhile, was 7th in the mid-season top 10, although he was still with the Indians at the time.
