The MLB's reserve clause gave owners rights to players after their contracts expired

In 1975, a Major League Baseball clause that kept players legally tied to their teams after retirement was dismantled

Players fought the "reserve clause" for years, citing the Sherman Antitrust Act of 1890, but to no avail—in fact, the Supreme Court ruled professional baseball was neither interstate nor commerce in 1922. Players effectively unionized in 1966, and by 1975, an arbitration panel ruling led to the dismantling of the reserve clause, which had been the only antitrust exemption in professional sports.

Free agency dramatically changed player compensation
