Peoria Sports Complex hosts dozens of tournaments and thousands of games annually for high school-aged baseball players. These tournaments are organized and executed by private organizations that feature the highest level of amateur youth competition in the United States. These tournaments often attract collegiate and professional scouts and premier "travel ball" clubs from around the country. The organizations producing the tournaments manage the registration fees, admission prices, retail operations, game schedules, tournament trainers, umpiring staff, travel agencies, etc. Peoria Sports Complex prepares the fields, provides support staff and amenities and operates concessions and cleaning services.
Peoria Sports Complex hosts local Little League season games, primarily played on weeknights and Saturdays during the spring into summer. Little League determines each team's schedule and is responsible for all elements of uniforms, coaches, umpires, etc. Peoria Sports Complex provides the same functions and services as it does for youth tournaments. Little League games for younger divisions are also held at Rio Vista Community Park and Pioneer Community Park.
