WILLIAMS CUP
MEN'S ISC CANADA WEST QUALIFIER

The Calgary Industrial Softball Association (CISA) proudly presents the Williams Cup, returning to Crawford's Fields in 2027 for its third edition as an International Softball Congress (ISC) Canada West Qualifier!

Established in 2025 in honour of longtime CISA player Jesse Williams, the association's oldest active player at the time, the tournament celebrates the rich history, dedication, and tradition of men's fastball in Calgary.

Building on the success of its first two editions, the Williams Cup brings together competitive men's fastball teams from across Western Canada to battle for championship glory and an opportunity to advance to the prestigious ISC World Tournament.

More than just a championship, the Williams Cup honours the generations who built Calgary fastball while helping grow the game for those who follow.

Fans and families are encouraged to come out and experience the excitement of championship fastball!

Stay tuned for tournament dates, registration details, schedules, participating teams, game results, playoff brackets, and championship updates.

Built on Legacy. Driven by Competition. One Cup. One Champion. 🏆🏆🏆
