WSCR's contract with the White Sox expired after the 2015 season. As first reported by Robert Feder of www.robertfeder.com, WLS (AM) 890, was to be the new White Sox flagship station from the 2016 through the 2021 seasons. However, WLS owner Cumulus Media filed for Chapter 11 bankruptcy protection in November 2017 and entered into a restructuring agreement with certain of its lenders to reduce more than $1 billion in debt. The Bankruptcy Court allowed Cumulus and WLS to end its contract with the White Sox. WGN became the new flagship station of the Chicago White Sox on February 14, 2018.
