How Many Minor League Baseball Teams Are There

Curious about how many minor league baseball teams are there? There’s an astounding total of over 120! Spanning from bustling cities to quaint towns, these teams are the hidden gems of baseball, nurturing tomorrow’s MLB stars today.

Join us on this exploration as we break down the numbers and characteristics of each level, where baseball’s future stars are shaped and polished! Let’s step up to the plate!

Understanding the Levels of Minor League Baseball


Minor League Baseball (MiLB) operates as the underbelly of Major League Baseball (MLB). It’s a vibrant ecosystem of local baseball teams, some affiliated with MLB clubs and others as independent entities.

As of the 2021 season, the number of teams in the MLB-affiliated minor leagues was trimmed to 120, spread across 11 leagues in the U.S. and Canada. This equates to four teams for each of the 30 MLB franchises.

Let’s examine everything from minor league baseball levels, team names to logos and the roles of these squads by state.

1. Triple-A (AAA)

1. Number of Teams


Triple-A consists of two affiliated leagues. These are the International League (20 teams) and the Pacific Coast League (10 teams). The former caters to teams from the Atlantic coast and midwestern U.S., while the latter focuses on the Pacific coast and southwest regions. Notably, Triple A teams often house both budding players and seasoned veterans.

2. Characteristics


Holding the esteemed title of the highest level in minor league baseball, Triple-A players are just a heartbeat away from the floodlights of Major League Baseball.

3. Team Names, Logos, and Beyond


Take, for instance, the Lehigh Valley IronPigs. As a Triple-A affiliate of the Philadelphia Phillies, their name and emblem aren’t just whimsical; they’re a nod to the region’s rich iron industry.

4. Age Limit and Roster Restrictions


At the Triple-A level, teams can maintain an active roster of 28 players. There’s no age or experience cap. Whether you’re a young gun aiming for the stars or a seasoned player with years under your belt, Triple-A welcomes all.

2. Double-A (AA)

1. Number of Teams


This classification boasts three leagues. They are the Eastern League (12 teams), the Southern League (8 teams), and the Texas League (10 teams). It’s worth noting that many top prospects are placed here, pitted against each other rather than facing the mix of minor and major league veterans in Triple-A.

2. Characteristics


Populating this arena are hotshot prospects. Here, the finesse gets finer, the throws get sharper, and the hits get harder. It’s an essential pitstop en route to baseball stardom.

3. Team Names, Logos, and Beyond


Moving to Double-A, teams like the Montgomery Biscuits bring a delightful mix of fun and tradition. Their logo, featuring a biscuit, is both playful and memorable. It’s a testament to how teams at this level balance competitive spirit and community engagement.

4. Age Limit and Roster Restrictions


Double-A mirrors its Triple-A counterpart in roster size, allowing 28 players. And just like Triple-A, there’s no holding back on experience. It’s a league that celebrates diversity in skill and age, making every game unpredictable and thrilling.

3. Class A-Advanced (High A)

1. Number of Teams


Situated a notch below Double-A, High-A, often referred to as “Class A-Advanced,” is a pivotal tier in the class a minor league baseball system.

This classification encompasses three leagues: the Midwest League with 12 teams, the Northwest League with 6 teams, and the South Atlantic League with 12 teams. Typically, this level acts as a second or third stepping stone for players in the minor league hierarchy.

2. Characteristics


This is where many get their inaugural taste of relentless, full-season baseball. The leap is monumental, both in terms of skill and stamina.

3. Team Names, Logos, and Beyond


In the High-A leagues, creativity knows no bounds. Teams here often experiment with vibrant colors and dynamic designs, ensuring they stand out and make a mark. It’s a visual treat for fans and a testament to the league’s energetic spirit.

4. Age Limit and Roster Restrictions


Things get a tad more intricate here. High-A teams can boast a roster of 30 players. However, there’s a catch. Only two players and a single player-coach can have six or more years of minor league experience. It’s a delicate balance, ensuring fresh talent gets ample spotlight while still valuing experience.

4. Class A (Low A)

1. Number of Teams


Positioned beneath High-A, single-a baseball teams were once known as “Class A.” This category comprises three leagues: the California League with 8 teams, the Carolina League with 12 teams, and the Florida State League with 10 teams. These local baseball teams mainly feature players advancing from the Rookie leagues, with a sprinkling of seasoned first-year players.

2. Characteristics


Here, the canvas is vast, and the paint is fresh. Young talents are sculpted and molded, with an age limit ensuring the league remains a hotbed for budding prospects.

3. Team Names, Logos, and Beyond


Single-A teams pack a punch with their identities. Their logos often mirror local landmarks or cultural icons, creating an immediate connection with their audience. It’s about local pride, and every game celebrates that bond.

4. Age Limit and Roster Restrictions


Single-A, much like High-A, permits 30 players on its roster. But the experience restriction tightens a bit. Only two players can have five or more years in the minor league trenches. It’s a nod to the league’s focus on nurturing emerging talent.

Rookie and Short-Season Leagues

1. Number of Teams


Serving as the foundational tier of MiLB, the Rookie classification includes leagues such as the U.S.-based Arizona Complex League, Florida Complex League, and the Caribbean-based Dominican Summer League. While the U.S. leagues play approximately 60 games each, the exact number of teams can vary, often determined by affiliation with MLB teams.

2. Characteristics


Designed for the greenhorns – draftees tasting professional baseball for the first time and international prodigies exploring the American baseball landscape.

3. Team Names, Logos, and Beyond


The Rookie leagues, though nascent, are no less in their branding game. These teams, with their fresh and often playful logos, signify hope and the future of baseball. They’re the starting point for many players, and their logos encapsulate that journey’s beginning.

4. Age Limit and Roster Restrictions


The Rookie leagues are where things truly diverge. While there’s no cap on the U.S.-based Rookie team size, only three players can have four or more years of minor-league experience.


Navigating the vast expanse of Minor League Baseball, we’ve uncovered the intricate layers that shape the future of the sport.
