The Frontier League is a professional independent baseball league founded in 1993. It is one of the longest-running and most established independent leagues in North America, offering a high level of competition outside of Major League Baseball’s affiliated minor league system.
The Frontier League operates as an MLB Partner League, meaning it works in collaboration with Major League Baseball but is not directly part of its farm system. This allows teams to operate independently while still maintaining a strong connection to the broader professional baseball landscape.
The league features 18 teams across the United States and Canada, with a focus on mid-sized and smaller markets. Teams stretch from Mississippi to Canada making up the Midwest and Atlantic leagues. Many Frontier League cities do not host affiliated minor league teams, making the league an important part of local sports culture.
The level of competition in the Frontier League is generally comparable to Single-A minor league baseball. Rosters typically include:
Recent college graduates
Undrafted players
Former minor league players
International talent
Many players use the league as a stepping stone to sign with MLB organizations.
The Frontier League season includes:
A regular season of 102 games
Divisional play
A postseason playoff system to determine the league champion
Games are typically played from around mothers day to labor day (May-September).
Although not directly affiliated with MLB teams, the Frontier League serves as a valuable platform for player development. Scouts regularly evaluate talent, and contracts are often purchased by MLB organizations.
Frontier League teams emphasize:
Affordable ticket prices
Family-friendly entertainment
Community engagement
Intimate ballpark settings
This creates a unique and accessible baseball experience for fans.
The league expanded significantly after merging with the Can-Am League in 2020, increasing its geographic reach and level of competition. Additionally, 2 teams were adding in 2025 bringing the league to 18 teams. It continues to grow as a key part of the independent baseball ecosystem.
