Is Posada's time behind the plate over?
Posada sports a MLB-worst 6.46 ERA. With Francisco Cervelli (who I am still shocked to see in the majors), the staff is pitching to a 4.45 ERA.
Cervelli has already coaxed a shutout from CC Sabathia, as well as the best start of the season from A.J. Burnett.
What do you think? Is it time for the Yanks to switch catchers?
