As an aside, and a note to parents of pitchers, a ball going into the backstop is not always a sign of a "bad" or "skill challenged" catcher, in fact it could be the sign of a smart catcher.
There are situations where it is more beneficial for the catcher to try and "pick" a bad pitch rather then block it. i.e. there's a runner on first or second that is stealing and catcher will have no chance to challenge the runner if he blocks the ball, so depending upon the backstop location etc., the catcher will attempt to pick and throw the ball, --afterall the runner will get the next base whether the catcher blocks the ball or it bounces off the backstop, but if the catcher is able to pick the ball he can challenge the runner, especially if the runner lets up a little when he sees the ball going into the dirt.
