Guaranteed Rate Field has served as the home ballpark of the Chicago White Sox since it opened on April 18, 1991, right across 35th Street from the site of the original Comiskey Park. Built for about $137 million, it was one of the last stadiums constructed in the multipurpose concrete “cookie-cutter” style before baseball-only retro parks like Camden Yards took over ballpark design.
The stadium has carried several corporate names over the decades, opening as Comiskey Park before becoming U.S. Cellular Field in 2003 and Guaranteed Rate Field in 2016. In December 2024, sponsor Guaranteed Rate rebranded the venue once again, shortening it to Rate Field starting with the 2025 season, though most fans still know it by its longer-running name.

The Fan Experience
A major 2001–2007 renovation removed the steep upper deck’s top eight rows and added a canopy roof, dramatically improving sightlines and comfort compared to the ballpark’s original 1991 layout, when capacity briefly climbed from 44,321 to about 47,000 before those seats were cut. Fans can also find nine bronze statues honoring White Sox legends around the outfield concourse, plus a video board and “exploding” scoreboard that pays homage to Bill Veeck’s famous original at old Comiskey Park.
The park’s amenities include 103 luxury suites, club seating on the 300-level, and family-friendly areas like the Kids Zone, making it a fixture of the South Side game-day experience.
History and Championships
The ballpark’s signature moment came in October 2005, when the White Sox swept the Houston Astros to win the World Series, ending an 88-year championship drought. It also hosted a piece of pitching history in July 2009, when Mark Buehrle threw a perfect game against the Tampa Bay Rays.
Built directly across the street from the original 1910 Comiskey Park, the stadium was designed to honor that ballpark’s name and legacy before later corporate sponsorships changed its identity multiple times.
