Historically the Cubs' system has not been known for producing position players. Outside of Shawon Dunston, Joe Girardi, Mark Grace and Ryan Theriot, the Cubs' organization has produced several one-year wonders and a catcher in Geovany Soto that the book is still out on.

Most that follow the Chicago Cubs know the name Starlin Castro ... the soon-to-be 20-year old shortstop that reportedly possesses all of the tools to be a solid shortstop at the big league level. But other than Brett Jackson, Josh Vitters and Kyler Burke, the top prospects in the Cubs' system are middle infielders.

The Cubs have depth up the middle with players such as Starlin Castro, Hak-Ju Lee, Darwin Barney, Junior Lake, Ryan Flaherty, Logan Watkins and DJ LeMahieu. These players could end up playing a role in the future of the Chicago Cubs, either on the field or in trades to improve the big league club ... but also the athleticism it takes to play up the middle could provide options for the Cubs down the road at other positions.
