Frontier League

The Frontier League (FL; French: Ligue Frontière, LF) is a professional baseball league in North America composed of 15 teams in the United States and three in Canada. The league is an official MLB Partner League and is the oldest active independent professional baseball league in North America. The league office is based at ForeFront Field in Avon, Ohio. The Frontier League was organized during the winter of 1992–1993 to bring professional baseball to communities in West Virginia, eastern Kentucky and southeastern Ohio that were unlikely to receive affiliated professional baseball clubs. It began with eight teams in 1993 and later expanded through new franchises, relocations and the 2019 merger with the Can-Am League. The league reached its present 18-team size with the additions of the Mississippi Mud Monsters and Down East Bird Dawgs in 2025. Beginning in 2026, each club plays a 102-game regular-season schedule. Eight teams qualify for the postseason. The reigning league champions are the Québec Capitales, who defeated the Schaumburg Boomers in the 2025 Frontier League Championship Series to win a fourth consecutive title. In April 2026, the league announced that it would rebrand as the National Association of Professional Baseball (NAPB) beginning with the 2027 season. The league stated that its history, statistics, records and team histories would continue under the new identity.
