Women's Pro Baseball League

The Women's Pro Baseball League (WPBL) is a professional women's baseball league in the United States. It will be the fifth American professional women's baseball league, after the All-American Girls Professional Baseball League (1943–1954), National Girls Baseball League (1944–1954), International Girls Baseball League (1952–1953), and Ladies League Baseball (1997–1998). Co-founded by Justine Siegal and Keith Stein, the league is planned to commence play in 2026, with four initial teams representing four cities across the United States: Boston, New York, Los Angeles, and San Francisco. Robin Roberts Stadium in Springfield, Illinois, will serve as a neutral venue for all games played during the inaugural season.

The league was founded in 2024 with an aim to elevate the visibility and proliferation of women's baseball, by establishing a path to professionalism for college and amateur players. It has no association with Major League Baseball. Maybelle Blair, Cito Gaston, Digit Murphy, and Ayami Sato assisted in the league's initial development. The league's competitions, played during summer, will consist of a four-week regular season and two-week postseason, partitioned by an all-star game. Games will last seven innings, and be played with aluminium bats. Teams will consist of 15–25 players, and be restricted to a total salary cap of US $95,000. The league intends to broadcast its games on a national network, instead of on regional sports networks.
