Class A Short Season (officially Short-Season A)[1][a] was a level of play in Minor League Baseball in the United States[b] from 1965 through 2020. In the hierarchy of minor league classifications, it was below Triple-A, Double-A, Class A-Advanced (created in 1990), and Class A. Teams in Class A Short Season played about 75 to 80 games per season, compared to the 130- to 140-game seasons of most professional baseball minor leagues.
As part of the 2021 reorganization of the minor leagues, Class A Short Season was eliminated along with its two leagues, the New York–Penn League and Northwest League.[2][3] Nine of the 22 active short-season teams were organized into new leagues at the High-A classification level.
