How we got free agents in baseball

The Reserve Clause in Major League Baseball functioned as a form of monopsony, granting team owners total control over player labor and suppressing wages for decades. In 1969, Curt Flood challenged this system by suing the league, arguing that the inability to negotiate with other employers violated his rights as a citizen. Despite losing his Supreme Court case, Flood’s public stand—famously declaring "a well-paid slave is nonetheless a slave"—shifted public perception and paved the way for future labor victories. This shift eventually led to the implementation of free agency, which fundamentally altered the economic landscape of professional sports. Consequently, the share of total revenue allocated to player salaries doubled, moving from less than 25% in the early 1970s to approximately 50% today, illustrating the transition of professional athletics into a modern, labor-conscious business model.
