The 1980 Major League Baseball season was the Chicago White Sox' 80th in Major League Baseball, and the team's 81st season overall. They finished with a record of 70–90, good enough for 5th place in the American League West, 26 games behind the first-place Kansas City Royals. In 1979 and 1980, Bill Veeck made overtures to Denver interests. An agreement was reached to sell to Edward J. DeBartolo, Sr., who pledged to keep the club in Chicago. His offer was turned down by the owners. Veeck was forced to sell to a different investment group.
