GCS Ballpark is a minor league baseball facility in Sauget, Illinois, that serves as the home ballpark for the Gateway Grizzlies of the Frontier League - officially sponsored by GCS Credit Union.



The Grizzlies' ballpark was built in time for the start of the 2002 season, under the original name of GMC Stadium. GCS Ballpark features reserved box seating, lawn seating, party suites, a hot tub suite, and a section of bleacher seating. With the bleacher section added in 2004, the stadium's capacity has increased to 6,000 fans (8,000 expanded).

In 2004, the Grizzlies became the first team in Frontier League history to draw over 200,000 fans for a season, finishing with a league best 217,500. Since the Grizzlies inception in 2001, the team has had a total of 37 players signed by MLB affiliates, and 14 signed since Manager Phil Warren took over in 2007.

ProGrass synthetic turf was installed at GCS Ballpark in January 2012, affording the organization much more opportunities to involve the community with out of season events.



GCS Ballpark hosted the 2008 NCAA Division II Baseball Championship. The stadium also served as the host for the annual wood-bat college baseball game between the Billikens of Saint Louis University and the Salukis of Southern Illinois University. GCS Ballpark has hosted the Illinois/Mizzou Braggin Rights game as well. The ballpark is also home for Webster University and Lindenwood University – Belleville. GCS Ballpark also services concerts, 5K runs, swap-meets, wrestling events, softball tournaments and leagues, and much more.

GCS Ballpark sells a unique food item called "Baseball's Best Burger", a variant of the Luther Burger. It consists of a bacon cheeseburger with a Krispy Kreme Original Glazed doughnut used as a bun. The ballpark and the burger were showcased in a special baseball-themed episode in season 2 of the Travel Channel’s Man v. Food.
