The Dixie Series was an Interleague Minor League Postseason Series pitting the playoff champions of the Southern Association and the Texas League in a best-of-seven matchup from 1920 to 1958. It was revived for one year in 1967, pitting the Southern League champ (the Birmingham A's) against the Texas League champ (the Albuquerque Dodgers). The A's won that final series four games to two.
