Joba Rules

The Yankees promote Joba Chamberlain to the major leagues—with a caveat. The 21-year-old has been a starter his entire career but the Yankees, seeking to bolster their bullpen, decide to convert him into a relief pitcher for the season's final months. To prevent overuse on the prized prospect's arm, GM Brian Cashman institutes a set of usage guidelines: No appearing on consecutive days, no entering a game in the middle of an inning and if he pitches more than one inning he gets two days off. These parameters quickly become known as the “Joba Rules,” spawning all kinds of merchandising spinoffs, including t-shirts, mugs, hats and posters.
