Major League Baseball has announced the rosters for the 2025 Arizona Fall League (AFL) season. Featuring 13 of MLB Pipeline’s Top 100 prospects and 97 organizational Top 30 prospects, the season begins with AFL Opening Night on Monday, October 6, as the Peoria Javelinas take on the Scottsdale Scorpions at Scottsdale Stadium.
