The Worst Episode Ever
In an episode that Jim Callis dubs the worst in MLB Pipeline Podcast history, he, Jonathan Mayo and Jason Ratliff break down the first of the 2023 organizational Top 30 Prospects lists. Against Jim's will, they do an impromptu -- and guaranteed-to-be-terrible -- ranking of the AL East and NL East farm systems, with the Orioles the clear No. 1 and the Nationals cited as the most improved. Jonathan has an interview with D-backs outfielder Druw Jones, the No. 2 pick in the 2022 Draft and the son of five-time All-Star Andruw Jones, that even Jim would have to admit is far from awful. And the guys mull which prospects qualify as both the best hitter and the best power hitter in their systems before tackling a listener mailbag question about which Top 100 Prospects Jim and Jonathan disagree about most. Terrible.
