Guaranteed Rate Field is a baseball park located in Chicago, Illinois, that serves as the home ballpark for the Chicago White Sox of Major League Baseball. The facility is owned by the state of Illinois through the Illinois Sports Facilities Authority, and is operated by the White Sox. The park opened for the 1991 season, after the White Sox had spent 81 years at the original Comiskey Park. It also opened with the name Comiskey Park but was renamed U.S. Cellular Field in 2003 after U.S. Cellular bought the naming rights at $68 million over 20 years. The current name was announced on October 31, 2016, after Guaranteed Rate, a private residential mortgage company located in Chicago, purchased the naming rights to the ballpark in a 13-year deal.The stadium is situated just to the west of the Dan Ryan Expressway in Chicago's Armour Square neighborhood, adjacent to the more famous neighborhood of Bridgeport. It was built directly across 35th Street from old Comiskey Park, which was demolished to make room for a parking lot that serves the venue. Old Comiskey's home plate location is represented by a marble plaque on the sidewalk next to Guaranteed Rate Field and the foul lines are painted in the parking lot. Also, the spectator ramp across 35th Street is designed in such a way (partly curved, partly straight but angling east-northeast) that it echoes the contour of the old first-base grandstand.
The park was completed at a cost of US$137 million. The current public address announcer is Gene Honda, who also serves as the PA announcer for the Chicago Blackhawks, NCAA Final Four, and University of Illinois Football.
