As head of the Major League Baseball Players Association from 1966 to 1982, labor economist Marvin Miller ushered in one of the greatest transformations in professional sports in the 20th century. Miller, who died Nov. 27 at 95, negotiated for higher minimum salaries and a generous pension system. But his main achievement was ending the reserve clause, which tied a player to one team. Thus began the era of free agency, with all its ramifications--and remunerations. "He was not a tough guy. He was a tough-minded person," Hall of Fame pitcher and former U.S. Senator Jim Bunning told Time. "You got down to the nitty-gritty of what you were trying to negotiate. He was unbending."
