The American Association (AA) was a minor league baseball league at the Triple-A level of baseball in the United States from 1902 to 1962 and 1969 to 1997. In both incarnations, it comprised teams primarily from Midwestern and South Central United States. Together with the International League, the American Association contested the Junior World Series which determined the championship team in minor league baseball, at least for the eastern half of the United States. Later, its teams would also compete in the Triple-A World Series, and its players in the Triple-A All-Star Game.
