The first player to wear #6 for the White Sox was outfielder Johnny Watwood in the 1931 season.
Carlton Fisk wore #72 for the White Sox during his time there between 1981-1993. Fisk signed with the White Sox in 1981 after having been with the Red Sox since 1969. His number with the Red Sox was 27 but that number was taken so he reversed the digits and wore 72. The White Sox retired the number in 1997.
According to Baseball Almanac, no one on the 1995 White Sox roster wore #21.
