The Red Sox have sent Triple-A catcher Mike McKenry to Pittsburgh in exchange for a player to be named later or cash considerations according to Chris Price of WEEI.
The Sox acquired Mike McKenry from the Rockies in exchange for Daniel Turpen on March 29 with hopes that he would increase their organizational depth at a position of some need. McKenry had actually put up some decent numbers in Pawtucket, hitting .274/.369/.421, but when the Sox were in need of a backup a few days ago, it was Luis Exposito who received the call.
We'll see if the player to be named later ever amounts to anything--sometimes you can find a decent long shot low-level prospect--but generally speaking these are the sorts of deals that end up being forgotten within a month.
With the open space both on the 40-man and in Pawtucket, it might be time for Mark Wagner to return from his rehab assignment in Salem.
