If you were thinking that the Boston stay of Yoenis Cespedes might be short—you now have more reason to feel that way. Cespedes announced on Monday that he is switching agents from Adam Katz of WMG to Shawn Corey Carter (otherwise known as 'Jay-Z') of Roc Nation Sports. The highly-annoying Carter got Robinson Cano his 10-year, $240 million contract with the Mariners. Considering Carter's hatred of the Red Sox, you can pretty much assume Ben Cherington will unload the 29-year old outfielder this off-season (rather than face him and 'Jay-Z' in free agency next year). Unfortunately—even if that does happen—we'd still have to deal with Carter since he represents Rusney Castillo as well.
