Jonathan Mayo Reveals Which Minor League Prospects Upped their Stock in the Arizona Fall League 2025

MLB Pipeline prospect analyst and reporter Jonathan Mayo visits the Jack Vita Show to recap the 2025 Arizona Fall League season.

Jonathan has worked at MLB.com since 1999, and is the author of the 2023 book Smart, Wrong, and Lucky: The Origin Stories of Baseball's Unexpected Stars.

The Arizona Fall League just wrapped up its 33rd season, with the Surprise Saguaros winning their third championship in four years. Jonathan spent two weeks this fall in Arizona and got a good look at this year's crop of talent. Which players were he and Jack most impressed by? Was Kevin McGonigle, MLB Pipeline's no. 2 overall prospect, truly the best player competing in AFL this year? Who were some of the other best prospects that played in Arizona this fall?

Who were some of this year's under-the-radar prospects? Who were some guys who were not in the Top 100 coming into the AFL season, that had a nice showing in the desert, and might move into the next Top 100 rankings (coming in January)?

Lastly, how do the Surprise Saguaros keep doing it? What sets them apart from the rest of the league? The Saguaros have appeared in six straight AFL Championship games, and have won the Championship three times over the last four years. Are they the team of the 2020s?
