Jim Callis, Jonathan Mayo and Jason Ratliff discuss several notable promotions on the latest edition of the Pipeline Podcast, including No. 3 overall prospect Walker Jenkins (Twins) to Double-A and Jasson Dominguez and Kumar Rocker to the big leagues. The guys welcome Red Sox middle infielder/center fielder Kristian Campbell for an interview in which he breaks down the reasons behind his breakout season. Afterward, they chat about recent additions to the Top 100 Prospects list (Pirates righty Thomas Harrington, Braves lefty Cam Caminiti, Reds third baseman Cam Collier) before answering a listener mailbag question about Marlins outfielder/third baseman Jacob Berry.
