While this year's World Series rosters feature 22 players who were at one time ranked among the top 100 prospects in baseball, some of the biggest stars on the Dodgers and Red Sox came from much humbler beginnings. On this week's Pipeline Podcast, Jim Callis and Jonathan Mayo break down the players in this year's Fall Classic. Callis discusses how the 2011 Draft impacted this current Red Sox team, while Mayo later gives an update on prospects playing in the Arizona Fall League.

On the MLB Pipeline Podcast, Callis, Mayo and Tim McMaster are your tour guides through all the unfolding stories and breaking news of baseball's top prospects.
