2025-26 fall/winter ball updates on Marlins players

Over the course of the 2025-26 offseason, 22 players from the Miami Marlins organization traveled the world and continued to get game reps, furthering their development and/or compensating for time they missed over the summer. In addition to the Arizona Fall League, they found work in the Dominican Republic, Venezuela, Puerto Rico, Mexico and Australia.

This page includes any Marlins offseason acquisitions who were fall/winter ball participants. Likewise, players who departed the organization in recent months via free agency, trade or waivers were removed.

Player names are linked to their Baseball-Reference pages. Hitters are listed at the positions they played in fall/winter ball, even if they've been used differently by the Marlins organization. Click to see their full fall/winter ball history.
