The Cardinals’ system is light at the top right now, with only a couple guys anywhere in their upper levels who could substantially help the major league team this year, but the lower levels are well-stocked with upside guys. The Cardinals have been aggressive in Latin America in recent years, right up to the current signing period, and they have already hit on several of the pitchers they’re signing. When the current rotation needs reinforcements, the Cardinals should have the starters ready.
