The Big House Ballgame

The Joliet Slammers will take the field for a one-of-a-kind exhibition game inside the historic walls of the Old Joliet Prison on April 30, 2026. Dubbed The Big House Ballgame, this event is the official kickoff for Joliet’s Route 66 Centennial celebration, highlighting the city’s unique history. The game revives a century-old tradition where organized baseball was once played by inmates at the prison. Set against the unmistakable limestone walls and guard towers, this promises to be a once-in-a-generation event. The Joliet Area Historical Museum is hosting the event, which connects America’s pastime with the city’s remarkable heritage.
