Outfielder Brad Wilkerson is in uniform, wearing No. 32, and working out with the other Red Sox position players at the team’s minor league training facility after officially signing a minor league deal could pay him as much as $2.5 million for one season. The 37-year-old figures serve in the role the Red Sox originally had earmarked for Mark Kotsay before Kotsay was forced to undergo back surgery, keeping him out until at least May.

Also making an appearance for the optional workout was outfielder Jason Bay. J.D. Drew, who revealed yesterday he still is dealing with lingering back soreness, was not among the participants on the field.
