Top 30 prospects: Updated Marlins list following 2025 draft, trade deadline

The internal debates were especially heated this time around, which bodes well for the long-term outlook of the Miami Marlins organization. Miami's farm system is deep. At Fish On First, we rank only 30 prospects at a time—there are dozens of others worth monitoring closely who could realistically grow into major league roles in the future.

Each player's previous ranking—as of June 2—is shown in parentheses. Click the hyperlink in a player's name to visit their prospect profile.
