The yankees and Red Sox have prospects??
This thread has gone on long enough. If you want to cite specifics, then fine. I already named teams that have brought up rookies and not played them full time. Cinci, TB, Cubs, Sox, Det, LA, Sea, Min among others. In some cases the rookies have played themselves into starting roles. But in some cases they rotate days playing with others. If you want to argue your one-tracked view on the issue, PM me, because im not looking at this old thread anymore to see other paragraph about your "expert" opinion on player development.
