Good Grief, If they are Major League ready they will end up in the majors, some day, only when they are ready.
The Twins are not a -- school for not ready for Prime Time players.
There is no such thing as blocking, not good enough to come up, they won't; the Twins have had enough situations with Rooker, Celestino, Cave, Hicks time.
The Twins are not a school for learning.
