Canadian American Association of Professional Baseball
On October 16, 2019, it was announced that the Frontier League would be merging with the Canadian American Association of Professional Baseball, absorbing five of its teams to form the largest independent professional baseball league. This added the New Jersey Jackals, New York Boulders, Quebec Capitales, Sussex County Miners, and Trois-Rivieres Aigles to the league; the Ottawa Champions, the last remaining Can-Am League team, was not invited to participate. The divisions were renamed, with the easternmost teams playing in the Can-Am Division and the westernmost in the Midwestern Division.
