The seemingly inevitable deal is apparently done. We still may not know exactly how to measure catcher defense, but we know who'll likely be doing some defending for the 2013 Mariners: veteran back-up Kelly Shoppach.

Unlike the Ronny Paulino deal, I'd assume this is a major league contract, meaning that the M's have another 40-man decision to make. Yoervis Medina may sleep a little less soundly tonight, and I can't imagine Carlos Peguero is safe either. They could also choose to drop someone a little more prospect-y but further from the majors – Julio Morban or Francisco Martinez come to mind.
