The 2021 American Association season is the 16th season of professional baseball in the American Association of Professional Baseball (AA) since its creation in October 2005. There are 12 AA teams, split evenly between the North Division and the South Division.
After the folding of the Texas AirHogs and the loss of the St. Paul Saints to the Minnesota Twins organization, the league added the Kane County Cougars as the 11th member of the AA with the Houston Apollos serving as the 12th team, operating as a road travel team for the season. Additionally, the Kansas City T-Bones rebranded to the Kansas City Monarchs to honor the original negro league team. The league was split up into two divisions, the North and South Division. The season will be played with a 100-game schedule, with two home series and two road series inside a teamsâ division, and one home series and one road series against the clubs outside its division. The top three teams in each division will qualify for the 2021 playoffs.
Current through September 6, 2021.
