All League Baseball

All League Baseball is operating in an active national landscape, as women’s professional baseball and softball advance. In 2026, the Women’s Pro Baseball League (WPBL), co‑founded by Justine Siegal and Keith Stein, is scheduled to begin operations with four teams across major US cities. This marks a significant expansion in opportunities for baseball at a club level ([en.wikipedia.org](https://en.wikipedia.org/wiki/Women%27s_Pro_Baseball_League?utm_source=openai)). Concurrently, the Athletes Unlimited Softball League (AUSL), backed by Major League Baseball, continues its development of professional women’s softball, with a 2026 season built around permanent home cities following its 2025 touring model ([en.wikipedia.org](https://en.wikipedia.org/wiki/Athletes_Unlimited_Softball_League?utm_source=openai)).
