Minor league affiliates tracker: How MLB's restructure shakes out

As part of its restructuring of the minor leagues, Major League Baseball formally announced the 120 teams who will fill each franchise's four affiliated slots beginning with the 2021 season.

MLB released a plan for two Triple-A divisions, and three divisions each for Double-A, High-A and Low-A with each franchise now having one team at each level. The restructuring reduces the number of affiliated teams from 160 to 120.
