Women and baseball...

Women have played organized baseball since the 1860s. Students at the all-female Vassar College formed baseball teams as early as 1866. In 1875 three men organized a women's baseball club in Springfield, Illinois, divided it into two teams, the Blondes and the Brunettes, and charged admission to see them play. In the early 20th century, barnstorming teams known as “Bloomer Girls” were formed in various parts of the United States and took on amateur and semiprofessional teams that included both men and women.

In its early stages, women's involvement in professional baseball was largely an attempt to profit from the novelty of female players. An Ohio woman, Alta Weiss, pitched for the otherwise all-male semiprofessional Vermilion Independents in 1907. Jackie Mitchell (1914-1987) (above) became the first female professional baseball player when she signed a contract with the minor league Chattanooga Lookouts in 1931 (she was really the second because in 1898 Lizzie Arlington played one game, pitching for Reading against Allentown). Mitchell pitched in an exhibition game against the New York Yankees and struck out their two star players, Babe Ruth and Lou Gehrig. Organized baseball formally banned women from signing professional contracts with men's teams in 1952.

When World War II made the suspension of major league baseball a possibility, the All-American Girls Professional Baseball League (AAGPBL) was founded with four teams—the Rockford (Illinois) Peaches, the Racine Belles and the Kenosha Comets (both of Wisconsin), and the South Bend (Indiana) Blue Sox. Annastasia Batikis ("Stash") played at Racine Belles.

The AAGPBL drew large crowds because of its players' athletic abilities. The league management, however, was concerned that the players appear feminine to the fans, and rules encouraging the wearing of lipstick and long hair and banning the wearing of trousers off the field were promulgated. On the field, the women initially played fast-pitch softball (which features a larger ball and underhand pitching), but by 1948 overhand pitching was introduced, and eventually the only difference of note between men's baseball and AAGPBL baseball was the size of the diamond, which in the AAGPBL had a shorter distance between bases. During its 11-year existence (1943–54), the league received a great deal of national attention, but by the 1950s the televising of major league baseball led to dwindling interest in the women's teams, and the league folded. These female players were eventually recognized with an exhibit at the National Baseball Hall of Fame and Museum in 1988. In 1992 the feature film A League of Their Own dramatized the story of the AAGPBL.

Beginning in 1994, the Colorado Silver Bullets, sponsored by a brewing company and managed by Hall of Fame pitcher Phil Niekro, competed against men's teams for four years. Between 1997 and 2000 Ila Borders, a left-handed pitcher, played for two men's teams in the independent Northern League.

Sports was one of the ways that women began assailing the traditional outdated notions about femininity and manliness. It was indeed a powerful venue because how else women could visibly prove that they were equal to men...
