On December 23, 1975, arbitrator Peter Seitz declares Andy Messersmith and Dave McNally free agents. Both pitchers sat out the option years of their contracts in the hopes they would become free to sign with any team. Messersmith will sign with the Los Angeles Dodgers, while McNally opted for retirement. Seitz’s decision will lead to an agreement with the owners, whereby all players will become eligible for free agency after six seasons.
