<Tr> <Th_colspan="2"> Tenants </Th> </Tr> <Tr> <Td_colspan="2"> Chicago White Sox (MLB) (1991--present) </Td> </Tr> <P> 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 . </P> <P> 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 . </P>
