U.S. Cellular Field a.k.a. "The Cell" or (formerly New Comiskey Park) is a baseball stadium in Chicago, Illinois. It is the home of the Chicago White Sox of the American League. The park opened for the 1991 season, after the White Sox had spent 81 years at Comiskey Park. The new park, completed at a cost of $167 million, also opened with the Comiskey Park name, but became U.S. Cellular Field in 2003 after U.S. Cellular bought the naming rights at $68 million over 20 years. It hosted the MLB All-Star Game that same year. A few sportscasters and fans, however, continue to use the former name, (new) Comiskey Park. Prior to the demolition of the Old Comiskey Park, Comiskey was the oldest in-use ballpark in Major League Baseball, a title now held by Fenway Park in Boston.
The stadium is situated at 35th Street and Shields Avenue in Chicago's Armour Square neighborhood ajacent to the Bridgeport neighborhood. It was built in the parking lot of old Comiskey Park, which was torn down and became a parking lot for the current park.
The stadium was the first new sports venue built in Chicago since The United Center opened in 1995. It was also the first baseball-only park since Royals Stadium (now Kauffman Stadium) opened in 1973, and the last built before the recent wave of new "retro-classic" stadiums. However, a few design features from the old park were retained. Most notable among them is the "exploding scoreboard," which is a replica of the one installed by Bill Veeck at the old park in 1960. At the beginning of all games, after a White Sox player hits a home run, and after a White Sox victory, the scoreboard lights up in color and fireworks explode in the sky. The entrance has several arched windows. The Sox Shower, located in left-center field, is a place where fans can cool off during hot gamedays.
As originally built, the park was criticized by many fans. To avoid overhang problems that were present in many stadiums built in the modern era, the upper deck was set back over the lower deck. However, this created one of the highest upper decks in baseball. The first row of seats in the upper deck at the new stadium is farther from the field than the highest row of seats in the upper deck at the old stadium. The new park's roof was much smaller than the old park's roof, and didn't completely cover the upper deck. Mike Veeck, son of the former White Sox' owner, once said, "It had everything but a soul."
In response to fan complaints, the stadium has undergone numerous renovations since its opening in order to retrofit the facility to current architectural trends. These new features have included building a multi-tiered concourse beyond center field, adjusting the fences to make the outfield less symmetrical and, most significantly, the removal of 6,000 seats at the top of the upper deck.
The uppermost story of the park now has a white and black screen behind the top row of seats and is topped by a flat canopy roof supported by poles that obstruct the view of a few seats. To give the park a "retro" feel the roof has black steel truss supports. The original blue seats were also replaced by forest green seats. The new green and black color scheme, upper level screen set back from the outer wall and canopy roof resembles the old Comiskey Park as well as other classic baseball stadiums. The White Sox have also added murals to the interior concourses, a prominent feature of the old stadium.
The stadium houses 84 luxury suites located on two levels, as well as thousands of "club seats" on 300-level mezzanine between the lower deck and upper deck. The club seats receive in-seat wait-staff and benefit from an enclosed concourse with multiple television viewing areas and bar-style concessions.
