The McHenry County Youth Sports Association has been hosting the Summer International Championship baseball tournament since 1993.  The MCYSA is a 501 c 3 nonprofit community organization.  We are supported by governmental partners including the City of Crystal Lake, the Crystal Lake Park District and the City of Woodstock.  We are staffed primarily with volunteers, many provided by our host teams, Phenom  Illinois and Crystal Lake Babe Ruth.  We are also financially supported by local businesses and individuals.   

The tournament first came to our area as the CABA (Continental Baseball Association) 15-Year Old World Series.  Over the years, the tournament has expanded to additional age categories and includes several international teams each year.  We regularly host teams from Japan, Brazil, Puerto Rico and Mexico.  In addition, clubs from the Dominican Republic, New Zealand, Sri Lanka, Canada, Russia, Lithuania and Aruba have participated in recent years.
