Magazine, "Sports Illustrated" Issue Featuring Curt Flood, August 19, 1968

Curt Flood was a gold-glove, all-star center fielder for the St. Louis Cardinals in the 1960s. In 1969, Flood challenged the Major League Baseball's reserve clause by refusing to be traded. Owners used the reserve clause to restrict the movement of players from team to team and to control player salaries. Though Flood lost, his stand for players rights eventually led to baseball's free agency.
