V-mart, the former Red Sox player turned "has-been", has just temporarily upgraded his status to "is" by hitting a grand slam against the Red Sox in the first inning. It is running shtick for lots of fans in lost of cities to say, "Why can't we get guys like that" when a former player comes back to bite them. Does anyone here know if there are published statistics on how players tyend tp perform versus their former teams as compared to how they do against the rest of the league?
