In 1952, the Boston Braves purchased the Negro League contract of Henry Aaron from the Indianapolis Clowns, a transaction that set the stage for baseball history.
Aaron would make his MLB debut with the Braves two seasons later, 23 years before he retired with the most revered record in American sports as baseball's home run king. But his call-up to MLB opened the door for another remarkable moment in baseball.
A second baseman named Toni Stone took Aaron's place on the Clowns' roster. In the process, she became the first woman to play baseball on a big-league team.
