Baseball: it's America's national pastime, and since the beginning, women have been playing the game. The first officially recorded baseball game in United States history took place June 19, 1846, in Hoboken, New Jersey, and in the decades that followed, professional teams of men and women sprouted up across the country. Women and girls played at colleges and community centers around North America. A black women's team, the Dolly Vardens, was started in Philadelphia in the 1880s. And women like Jackie Mitchell, Toni Stone, and Mamie "Peanut" Johnson played alongside men in the professional leagues. Then, in 1943, with many of the men of Major League Baseball away at war, the All-American Girls Professional Baseball League was formed, pulling together skilled female athletes from across the U.S. and Canada to form "a league of their own." In recent decades, female athletes like Maria Pepe, Ila Borders, Mo'ne Davis, and Eri Yoshida have continued to challenge themselves and others to be the best in baseball. From the Negro leagues to the AAGPBL and beyond, we look back at the history of women in baseball and remember some of baseball's best.
