American Association of Professional Baseball

The American Association of Professional Baseball is an independent professional baseball league founded in 2005. It operates in the central United States and Canada, mostly in cities not served by Major League Baseball teams or their minor league affiliates. Joshua Schaub is the league commissioner. League offices are located in Moorhead, Minnesota. Though a separate entity, the league shared a commissioner and director of umpires with the Canadian American Association of Professional Baseball during that league's existence. The American Association of Professional Baseball has 501(c)(6) tax-exempt status with the Internal Revenue Service. In 2020, as part of MLB's reorganization of the minor leagues, the American Association, together with the Atlantic League and the Frontier League, became an official MLB Partner League.
