White Sox ballpark name changes to Guaranteed Rate Field

CHICAGO (WLS) -- The Cell is no more. The name of the White Sox ballpark officially became Guaranteed Rate Field on Tuesday.

Crews removed U.S. Cellular Field signs and installed the new logos on Monday.

A 13-year deal announced in August gives the mortgage lender the naming rights for the team's home ballpark in Chicago. The White Sox retain an option under the team's lease for the ballpark, which if exercised, could extend this naming rights deal an additional year through 2030.

Guaranteed Rate is a Chicago-based online mortgage lender known for its late night commercials with pitchman Ty Pennington. The home-grown 16-year-old company is also the nation's eighth-largest mortgage lender.

"To have a Chicago-based company by people who are passionate about Chicago, passionate about Chicago sports, it's a great partner for us to have," White Sox Vice President Brooks Boyers said when the name was announced in August.

The White Sox played at New Comiskey Park from 1991-2002 before a naming rights agreement changed the ballpark's name to U.S. Cellular Field from 2003-2016.
