Badler's in the midst of some minor league catching analysis. He had this blurb to say on Castillo, though, in his "The Bad" section on the passed balls article. "Welington Castillo: The 21-year-old Castillo batted a composite .287/.337/.383, mostly split between high Class A Daytona and Double-A Tennessee. Castillo has good defensive tools, most notably a plus arm. His blocking and receiving tools are solid, but they don’t show up with enough frequency yet, as it’s one of the many phases of the game in which Castillo is still relatively raw. With Geovany Soto still under the Cubs’ control for five more seasons, there’s little need to rush Castillo." ___________________________ This fits with what's been suggested about Castillo, a guy who could be great defensively but isn't there yet.
