Development

The International Softball Congress (ISC) is committed to building the future of men’s fastpitch by supporting young athletes and the programs that introduce them to the game. The Carrol Forbes Foundation (CFF), created in 1995 in honor of ISC founder Carrol Forbes, helps us do exactly that by providing funding for youth clinics, tournaments, and other development initiatives.
Each year, the Foundation offers up to $1,500 for approved youth-focused activities that grow skills, participation, and passion for fastpitch. To apply, simply complete the appropriate form and send it to CFF Chair Greg Nydick.
