when did free agency start in the mlb

MLB free agency is generally considered to have started in 1976 , after the landmark Messersmith-McNally ruling in late 1975 opened the door for players to become free agents. The system then officially took hold in MLB the following year, with players needing six years of service time to qualify.

Quick Scoop

• The key turning point was December 23, 1975 , when arbitrator Peter Seitz ruled in favor of Andy Messersmith and Dave McNally.

• That ruling effectively ended the old reserve-clause system that tied players to one team indefinitely.

• 1976 is the year most often cited as the start of MLB free agency in practice.

Why that matters

Before free agency, teams had much more control over players’ careers. After the ruling and the new agreement that followed, players gained the ability to negotiate with other teams once they had enough service time.

TL;DR

MLB free agency started in 1976 , with the legal breakthrough coming in late 1975.
