File-This 1968 file photo shows St. Louis Cardinals outfielder Curt Flood. Flood set off the free-agent revolution 50 years ago Tuesday, Dec. 24, 2019, with a 128-word letter to baseball Commissioner Bowie Kuhn, two paragraphs that pretty much ended the career of a World Series champion regarded as among the sport's stars but united a union behind his cause.
