Official Launch of ISC Leagues: A New Era for Fastpitch Softball

The International Softball Congress (ISC) is proud to officially announce the launch of ISC Affiliated Leagues — an initiative designed to strengthen, connect, and grow men’s fastpitch at the league level across North America and beyond.

For nearly eight decades, the ISC has been the global standard for elite men’s fastpitch competition, best known for the ISC World Tournament and its commitment to preserving the highest level of the sport. With the introduction of ISC Leagues, that same standard now extends directly to local and regional leagues, creating a unified pathway that supports players, teams, organizers, and fans year-round.

ISC Leagues are built to:

  • Unify leagues under one recognized international structure
  • Enhance visibility and credibility for local competition
  • Create clearer pathways to ISC-sanctioned events
  • Support league organizers with digital tools, promotion, and governance
  • Grow the game at the grassroots level while honoring its elite traditions

This initiative is more than a name — it’s a commitment to collaboration, consistency, and long-term growth. By bringing leagues together under the ISC banner, we strengthen the foundation of men’s fastpitch while ensuring the sport continues to thrive for future generations.

Leagues, teams, players, and supporters are invited to learn more about ISC Leagues, including structure, benefits, and how to become a ISC Affiliated League.
