Considered a pioneer, Toni Stone was the first woman to play baseball in the Negro Leagues–and–in the 1950s men’s leagues. Despite the odds of succeeding, Stone blazed a historical path in the male-dominated sports world, crushed “female” expectations, and created her own set of rules. Based on Martha Ackmann’s book, Curveball: The Remarkable Story of Toni Stone, award-winning playwright Lydia R. Diamond, (Smart People, The Bluest Eye), has adapted the dynamic and uplifting story of Stone’s journey to do what she loved the most: play baseball.
