With an 81-57 record, the Birmingham Barons (Double-A affiliates of the Chicago White Sox) were the best overall team in the Southern League in 2025.
A 43-26 record in the second half also had the Barons placing first in their division, therefore clinching a playoff spot.
Per league rules, the Southern League playoffs will consist of four total teams in a best-of-three division series, followed by a best-of-three championship series.
The White Sox made some internal promotions to get the roster ready for the playoffs, and the Barons kicked off the postseason on Tuesday night with a game against the Chattanooga Lookouts.
