Perhaps the best selling point for the additions of rental veterans Jon Lester and J.A. Happ, on top of the fact the Cardinals' rotation has been so shaky the hurlers might be able to offer legitimate help despite their bloated ERAs, was that their arrivals did little damage to the farm system.

Calling up top pitching prospect Liberatore and top position prospect Gorman is the fun idea.
