Re: Catchers: How important is "framing a pitch"?

From that same BP article:

" . . . And Mathis “earns” an extra strike call every two games or so. If switching a ball to a strike is worth .161 runs, as Dan Turkenkopf found, Mathis has an edge of about 10 runs over a full season, by pitch-framing alone."
