The Yankees currently have two catchers on their projected Opening Day roster, but the differences between Jorge Posada and Jose Molina are extensive. Meanwhile, with Posada’s working his way back from a very serious injury, his catching 140+ games this season is no sure thing. To that end, Steven Goldman wonders if the Yanks would be best off signing a second starting catcher. He makes a compelling case for the argument, but the Yanks’ options are Jason Varitek and Pudge. While both could be had for the right price, they don’t add much offensively to the team. The Yanks will sink or swim with Posada. Hopefully, his shoulder can carry the load.
