More Top 100 Talk (Guest: Owen Caissie)
As work continues on team Top 30 rankings (coming the week of March 3!), there are still plenty of ways to slice and dice the already-released lists. On this week's episode of the MLB Pipeline Podcast, Jim Callis, Jonathan Mayo and Jason Ratliff do just that, starting with Jim and Jonathan drafting off the positional Top 10s, with the caveat of filling outa lineup while taking one prospect per ranking spot. After that, Jim chatted with Cubs outfield prospect Owen Caissie (No. 54 on the Top 100) before the gang talked about some prospects who just missed the list. As always, the episode concludes with a question from the mailbag, this time discussing who could make a Jackson Merrill-like jump to the big leagues in 2025. Learn more about your ad choices.

It's ranking season! (Guest: Kyle Teel)
The 2025 ranking season is underway and the MLB Pipeline Podcast wastes no time digging in to the first top 10 by position lists that have been published. Jim Callis, Jonathan Mayo and Jason Ratliff break down the top 10 catchers list, which features nine of the 10 backstops from a year ago as well as the top 10 first basemen, with eight new names among them. Then the guys welcome in one of the catchers high up on that list, Kyle Teel, who was recently traded to the White Sox in the Garret Crochet deal. It's also the start of the international signing period, so the pod shifts to looking at the top names on the MLB Pipeline international Top 50, starting with the one creating the most buzz, Japanese right-hander Roki Sasaki, before finishing up with a Mailbag question about international prospects who could land on the Top 100 a year from now.

Looking back, looking ahead
In the final MLB Pipeline Podcast of 2024, Sam Dykstra and Jonathan Mayo take time to review the year that was as well as look ahead to what might be. They kicked things off by highlighting their favorite prospect-related moments from the '24 season, from the Paul Skenes-Jackson Holliday Spring Breakout matchup all the way through to seeing Andrew Painter pitch in the Arizona Fall League. Then they turned the page to look ahead to what's sure to be an exciting 2025 by discussing some intriguing storylines, including whether pitching prospects are back and who will be the No. 1 pick in the Draft. One of the biggest storylines will undoubtedly be Roki Sasaki, and Sam and Jonathan broke down which teams are best positioned to sign him before finishing things up by playing Santa for the Blue Jays farm system in this week's listener Mailbag.
