The Chicago Cubs are flying high after winning the World Series, but they are well aware of potential holes in their farm system.

The Cubs feel there is a need for pitching depth, especially among starters at the higher levels of the Minor Leagues.

"Organizationally, we really don't have the impact starters at the upper levels," Jason McLeod said. "I do think with the volume of arms we have taken over the past few years and signed internationally, guys are coming on. We now feel really good, not just with the depth of the organization but having some major league starting impact guys who are at the the A-ball level and progressing toward Double-A now."
