The Joliet Slammers announced earlier this month that they will play an official pre-season exhibition game inside the walls of the historic Old Joliet Prison on April 30, 2026, marking a rare return of professional baseball to a former correctional facility.

The event, titled “The Big House Ballgame,” will serve as the official kickoff to the Route 66 Centennial Celebration in Joliet, with a scheduled 3:05 p.m. first pitch. The game will take place entirely within the prison grounds, where organized baseball was once played regularly by inmates for nearly a century.
Baseball was first introduced at Joliet Prison in 1914 by Warden Edmund Allen as a way to improve morale and encourage good behavior. Games continued at the prison through multiple generations until the facility closed in 2002. The upcoming exhibition revives that history in a modern setting, placing a professional team back on a field once used for recreation behind bars.

“The Big House Ballgame is exactly the kind of big idea event that gets us fired up as a team,” said Night Train Veeck, part-owner of the Joliet Slammers. “We love being a part of special moments that bring people together and give them a memory they’ll be talking about for a long time.”
The Slammers are members of the Frontier League, an MLB Partner League with 18 teams across the Midwest and East Coast. Their game at Old Joliet Prison will be one of six official Route 66 Centennial satellite events nationwide, alongside celebrations in cities including Santa Monica, Albuquerque, Amarillo, Springfield, and St. Louis.

Locally, the event is supported by Will County Government, Heritage Corridor Destinations, Sportsfields Inc., and the Joliet Area Historical Museum, which operates the Old Joliet Prison Historic Site. Officials have indicated the game will anchor a broader slate of community events throughout the city.

The announcement arrives during baseball’s offseason, a time traditionally associated with reflection across the sport. As the calendar moves toward Christmas, the return of baseball to a former prison yard highlights a lesser-known but longstanding chapter in the game’s history — one where baseball served as structure, recreation, and connection in places far removed from packed stadiums.
