A new professional women's softball league launched in June 2025, financially backed by Major League Baseball. Former MLB executive Kim Ng was named commissioner — the first woman to hold such a position for any U.S. major league. The league will transition from a barnstorming tour to city-based teams in 2026.
MLB-Backed Women's Professional Softball League Launches With First Female Commissioner in US Major League History
Women's professional softball in the United States has entered a new era with the launch of a major league backed by the financial and institutional power of Major League Baseball. The league debuted on June 7, 2025, marking the first time MLB has directly supported a professional women's sports league.
In a move that made sports history, former MLB executive Kim Ng was named the league's commissioner — becoming the first woman to hold the top leadership position for any U.S. major professional league. Ng previously made history in 2020 when she was hired as general manager of the Miami Marlins, becoming the first woman and first Asian American to serve as GM in MLB.
“The league debuted on June 7, 2025, marking the first time MLB has directly supported a professional women's sports league.”
The league launched as a barnstorming tour format in its inaugural season, with teams traveling to cities across the country to showcase the sport and build local fan bases. The response exceeded expectations, with packed venues and strong television ratings demonstrating the appetite for women's professional softball.
Building on that momentum, the league announced plans to transition to city-based teams in 2026, giving fans permanent home teams to support and players stable communities in which to live and train. The move mirrors the successful evolution of other women's professional leagues that have grown rapidly in recent years.
The explosive growth in softball participation and exposure — fueled in part by the sport's Olympic profile and the rising prominence of college softball — created the conditions for a sustainable professional league. Youth softball participation has been climbing steadily, and collegiate softball has become one of the most-watched women's sports on television.
With MLB's financial backing, broadcasting infrastructure, and marketing expertise behind it, the league represents the most significant investment in professional women's team sports in U.S. history. Players finally have a clear professional pathway, and young girls with softball dreams now have elite role models competing at the highest level.
