2026-27 fall/winter ball updates on Marlins players

Over the course of the 2026-27 offseason, we will once again see players from the Miami Marlins organization travel the world and continue to get game reps, furthering their development and/or compensating for time they missed over the summer. In addition to the Arizona Fall League, expect them to latch on with teams in the Dominican Republic, Venezuela, Puerto Rico, Mexico and Australia.

Any fall/winter ball participants who are employed by the Marlins organization will be included below. Players who depart the organization over the course of the offseason via free agency, trade or waivers will be 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.
