So you're saving them from ST games, so they can play in minor league games? That makes no sense to me; I mean don't pitch a guy at 0 (0) in ST, but as long as they're normally rested, get them as much work as possible.. Even un-invited, young, non-invited prospects can have gains during ST as there's a minor league portion of ST that we don't see. My theory, get them as many at bats, appearances w/ the better coaches that typically occupy your major league coaching staff.
