The Red Sox are set to callup catcher Christian Vazquez from Triple-A Pawtucket Wednesday, after A.J. Pierzynski was designated for assignment.
Manager John Farrell confirmed the move as lineups were released for Wednesday's game against the White Sox, and they had Vazquez in the starting lineup. The 23-year-old was hitting .279/.336/.385 at Triple-A Pawtucket this season.
