When can a minor-league player file for free agency?
Six (6) years after a minor league player s first season ends with an organization, if the player is not on the major league 40-man roster, he is eligible for minor league free agency. (If a player is on the 40-man roster, this rule does not apply.) Sometimes referred to as a six-year minor league free agent, the name comes from six renewable years on a player s contract.
