Updated 2025 MLB system rankings: Prospect insights, analysis - ESPN

Much has changed since we ranked all 30 MLB farm systems before the 2025 season. A big part of that shift has come in the past few weeks as the most recent prospects joined their new teams via the MLB draft and then front offices added — or subtracted — young players at the MLB trade deadline.

With two of the most impactful periods for any farm system in the rearview, it's time to see how all 30 organizations stack up and what has changed most since Opening Day.

This also isn't a random occurrence or glut of players who are about to graduate from being prospects at once. Ronny Mauricio and Luisangel Acuna already graduated this year, Christian Scott graduated last year, Brett
