After being traded away from the St. Louis Cardinals—a team he did not want to leave—in late 1969, the outfielder challenged Major League Baseball's reserve clause, a relic of baseball's earliest years that allowed teams to hold on to players in virtual perpetuity. Flood's case made it all the way to the Supreme Court. But he lost, and the fight took its toll.
