The first woman to become a professional baseball team owner was Billie Jean King. In 1974, she took over ownership of the New York Stars of the World TeamTennis league, breaking gender barriers in a male-dominated sport. King's involvement as a businesswoman in sports paralleled her advocacy for gender equality, making her a powerful figure in both athletics and the feminist movement. She utilized her platform to promote equal pay for female athletes and challenge sexism within sports, and her pioneering actions have left a lasting legacy in both tennis and sports management.
