The Triple-A National Championship Game, previously known as the Bricktown Showdown, is a single championship game held annually between the league champions of the two Triple-A leagues of Minor League Baseball to determine an overall champion of the classification. When last held in 2019, these leagues were the International League and Pacific Coast League. In conjunction with Major League Baseball's restructuring of Minor League Baseball in 2021, these leagues disbanded, and Triple-A teams were reorganized into the Triple-A East and Triple-A West. The 2021 schedule does not include a scheduled posteason for league championship playoffs or the Triple-A National Championship Game.
