What's really needed is a new rule in Major League Baseball to accommodate rookies that could use a cuppa coffee in the bigs. The Coffee rule would allow a team to call up five separate non-40 guys per year, but only one at a time, while putting a guy on the 40 into a temporary pool of players that cannot play with the club, but are not off the official 40-man roster. A Limbo guy could play in the minors while the Coffee guy is up. The limit for a cuppa coffee would be three starts for a minor league pitcher, or ten games for non-pitcher. At the end of that time, the Coffee guy can either return to the minors, or swap places with the Limbo guy on the 40-man. Otherwise, the Limbo guy simply returns to the 40, with no other changes in status. A rule like this would allow Jorge to replace Mejia for a few games, or Garver to replace Gimenez for ten games, with no worries about messing up the 40. This would allow rebuilding teams like the Twins to experiment more, give a veteran a rest, etc.
