Fresh from his journey to see Aledmys Diaz and the Cardinals' Class AA affiliate in Springfield, Mo., Post-Dispatch uber-writer Ben Frederickson joins the Best Podcast in Baseball. This is a special episode recorded at the downtown studios of Free Play Media, the new home of The Writers' Block. Frederickson and BPIB co-host Derrick Goold, a baseball writer at The St. Louis Post-Dispatch, discuss what Diaz has to accomplish on his rehab assignment and why the importance of his return to the Cardinals from a hairline fracture is such an unexpected twist for the 2016 club and its need for reliable defense. The two writers also delve into whether it's right for major-league players to rehab during minor-league playoffs and much more. It's an abbreviated BPIB episode, focused squarely on Frederickson's reporting and insight from Class AA. A full-length whiz-banger of an episode will drop in time to advance the forthcoming visit to Busch Stadium by the inevitable division champions, the Chicago Cubs.
