When it comes to evaluating a farm system, few things offer a better glimpse of the external view than the trade deadline and nothing gives greater clarity on the internal view than when there's a need at the major-league level. 

Consider the Cardinals.

St. Louis Post-Dispatch baseball writer Daniel Guerrero recently visited Memphis, Tennessee, to scout just that -- how actions at the big-league level relate to the production and development of top prospects at the higheset affiliate. Guerrero returned with stories for StlToday.com on Jordan Walker, Thomas Saggese, Victor Scott II, and several pitchers. And he joins the Best Podcast in Baseball and baseball writer Derrick Goold to discuss if there's advancement coming from Memphis or just idling talent in Memphis. 

An injury to Steven Matz at the beginning of May opened a spot in the Cardinals' rotation, and as they await the lefty's return they have at least twice had a chance to promote a prospect from within to make those starts. They did not. Actions always speak louder than rankings, and for the Cardinals their actions at the big-league level have suggested they feel it's more important for some of their prospects to continue developing in Class AAA Memphis than have their routine upset with a spot start, or, in some cases, that they're not ready to contribute to the majors even in a spot start.

It's a telling decision from the team that also strikes at their situation in the outfield.

The Cardinals are going to need contributions from the the organization in both the outfield and on the mound, and how they utilize their top affiliate is a chance to scrutinize the prospect pipeline and player development.

The two baseball writers conclude the episode by making their picks to represent the Cardinals in the Futures Game.
