Draft fever.... catch it! (Guest: Grady Emerson) Apr 29, 2026

Show notes

With the brand new Draft Top 150 dropping at the end of this week, it's clear the Pipeline Podcast crew has a serious case of Draft fever. Jim Callis, Jonathan Mayo and Jason Ratliff kick off this episode by looking at the four quadrants of the class -- college hitters and pitchers, high school bats and arms -- putting a grade on and talking about some intriguing guys in each sector. After the weekly Roch Watch, Grady Emerson, one of the top overall players in the class, joins the show. The guys still have energy for the Minor League guys, and plenty of time is devoted to prospects who just got called up to the big leagues (like last week's guest, Travis Bazzana) as well as new additions to the Top 100 (Logan Henderson and Kevin Defrank) before answering a Mailbag question about the future of the Brewers infield.

"The Next Randy Johnson" arrives! Apr 14, 2026

Show notes

We're always on the lookout for the next big prospect callup, but never has one been this big! Jim Callis, Jonathan Mayo and Jason Ratliff kick off this week's Pipeline Podcast with a breakdown of the 6-foot-10 Noah Schultz, the lefty who was called up to make his big league debut on Tuesday, with his size and swing-and-miss stuff drawing comparisons to the Big Unit. Schultz serves as a jumping off point to talk about which Top 100 prospects could be next to get the call, from fellow White Sox lefty Hagen Smith to Tigers outfielder Max Clark. From there, the guys shift attention to the Draft, with Jason having seen Roch Cholowsky in person during UCLA's matchup at Rutgers last weekend. The talk of that Friday night game was RHP Logan Reddemann and his 18-strikeout performance, and he was among the college arms moving into first-round consideration discussed on the pod. Talk returned to the Minors, discussing two newcomers to the Top 100 and our first Prospect Team of the Week before answering a question from the Mailbag.
