Total Number Of MLB Teams
As of today, Major League Baseball (MLB) is made up of 30 teams. These teams are evenly split between two leagues: the American League (AL) and the National League (NL), with 15 teams in each league. This even distribution has been in place since 2013, when the Houston Astros moved from the National League to the American League. This move helped create a balanced competition between the two leagues.
Every year, these 30 teams compete in the regular season with the goal of making it to the postseason and ultimately winning the World Series. The league’s structure, which includes several divisions within each league, adds to the excitement and rivalry as teams fight for both divisional titles and wildcard spots that provide additional chances to enter the playoffs.
The widespread location of these teams across the United States and Canada means that MLB has a broad and passionate fan base, with supporters cheering on their local teams from coast to coast.
Breakdown: American League And National League
Major League Baseball (MLB) is divided into two distinct leagues: the American League (AL) and the National League (NL). Each league consists of 15 teams, and both leagues are further subdivided into three divisions: East, Central, and West. This structure helps organize the regular season’s schedule and determines the matchups leading to the postseason.
American League (AL)
The American League, established in 1901, is known for being the first league to adopt the designated hitter (DH) rule, which allows teams to use a player to bat in place of the pitcher without the pitcher having to leave the game. The AL is divided into three divisions:
- AL East: This division includes teams like the New York Yankees and the Boston Red Sox, two of the most storied franchises in baseball history.
- AL Central: Known for teams like the Chicago White Sox and the Cleveland Guardians, this division often showcases intense rivalries.
- AL West: Home to the Houston Astros and the Oakland Athletics, this division has seen significant competition, especially in recent years.
Each of the divisions under the American League contributes to the competitive and cultural fabric of Major League Baseball.
National League (NL)
The National League, founded in 1876, is the older of the two leagues and traditionally did not use the designated hitter rule until recent years, when it was introduced during the 2020 season. The NL is also divided into three divisions:
- NL East: Teams like the Atlanta Braves and the Philadelphia Phillies dominate this division, bringing strong performances year after year.
- NL Central: Featuring teams such as the St. Louis Cardinals and the Chicago Cubs, this division has a rich history and passionate fanbases.
- NL West: The Los Angeles Dodgers and San Francisco Giants are key teams in this division, both with a history of success and fierce rivalry.
Each division within the NL is fiercely competitive, and teams strive to win their division title as the first step toward a playoff berth.

History Of MLB Teams
The history of Major League Baseball (MLB) teams is as rich and varied as the sport itself. Since its inception, MLB has seen teams rise and fall, relocate, and change names, reflecting the broader changes in American society and the economy.
Early Beginnings
The National League (NL), established in 1876, is the oldest of the two MLB leagues. It began with teams such as the Chicago White Stockings (now the Chicago Cubs), the Boston Red Stockings (now the Atlanta Braves), and the Cincinnati Red Stockings (now the Cincinnati Reds). These teams were among the original eight that formed the backbone of professional baseball in the United States.
The American League (AL) was established later, in 1901, as a rival to the National League. Initially known as the Western League, it rebranded to the American League and soon established itself as a major competitor. By 1903, the NL and AL reached an agreement to coexist under the MLB umbrella, leading to the first World Series that same year.
Expansion And Evolution
Over the decades, MLB has expanded significantly. In the early 20th century, teams were primarily located in the northeastern and midwestern United States. However, as the country grew and transportation improved, MLB began to expand westward. The first major expansion occurred in the 1960s, with the addition of teams like the New York Mets, Houston Astros, and the California Angels.
Another wave of expansion came in the 1990s, with the introduction of teams such as the Arizona Diamondbacks and the Tampa Bay Rays. This period also saw significant relocations, such as the Montreal Expos moving to Washington, D.C., to become the Washington Nationals in 2005.
Modern Era
Today, MLB teams are spread across the United States and Canada, reflecting the sport’s broad appeal. The league has grown to include 30 teams, each with its own storied history and traditions. From the early days of teams like the Boston Red Sox and the St. Louis Cardinals to the modern dynasties of the New York Yankees and the Los Angeles Dodgers, the history of MLB teams is a testament to the enduring popularity of baseball.
Expansion And Relocation Of MLB Teams
The history of Major League Baseball (MLB) is marked by several key periods of expansion and relocation, which have shaped the league into what it is today. These changes reflect the growth of the sport, the shifting demographics of the United States, and the economic factors that influence professional sports.
Early Expansions
The first significant wave of MLB expansion occurred in the 1960s. As the population of the United States grew, particularly in the western and southern regions, MLB recognized the need to establish teams in these areas. In 1961, the American League added the Los Angeles Angels (now known as the Los Angeles Angels of Anaheim) and the Washington Senators (who would later become the Texas Rangers). The National League followed in 1962 by introducing the New York Mets and the Houston Colt .45s (now the Houston Astros).
This period of expansion continued into the 1970s, with teams like the Kansas City Royals and the Seattle Mariners joining the league. These expansions helped to create a more geographically diverse league and brought MLB to new fanbases across the country.
Relocations
While expansion brought new teams to the league, relocation has also played a significant role in MLB’s evolution. Teams have moved for various reasons, including financial struggles, the pursuit of new markets, and stadium issues.
One of the most notable relocations occurred in 1958 when the Brooklyn Dodgers moved to Los Angeles and the New York Giants moved to San Francisco. This move marked the first time MLB teams were based on the West Coast, reflecting the growing importance of this region in American culture and economy.
In 1972, the Washington Senators moved to Texas, becoming the Texas Rangers. Another significant relocation happened in 2005 when the Montreal Expos moved to Washington, D.C., and were renamed the Washington Nationals, marking the return of MLB to the nation’s capital after a 33-year absence.
Modern Expansion
The most recent expansion in MLB occurred in the 1990s. In 1993, the National League added the Colorado Rockies and the Florida Marlins (now the Miami Marlins). In 1998, the league further expanded by adding the Arizona Diamondbacks and the Tampa Bay Devil Rays (now the Tampa Bay Rays).
These expansions were driven by the desire to tap into new markets and grow the sport’s fanbase. The introduction of teams in Florida, Arizona, and Colorado reflected the changing demographics of the United States, with these states experiencing significant population growth.
Future Considerations
Today, discussions about MLB’s future include potential expansion to new cities, both in the United States and internationally. Cities like Las Vegas, Portland, and Montreal are often mentioned as potential locations for new teams or relocated franchises. These discussions highlight MLB’s ongoing evolution and the league’s commitment to growing the sport.
Final Thoughts
Major League Baseball (MLB) has come a long way since its early days in the late 19th century. From the initial formation of the National League and American League to the present day, the league has expanded, relocated teams, and adapted to the changes in sports and society.
For anyone interested in baseball, understanding the number and structure of MLB teams is fundamental to appreciating the sport. From legendary franchises like the New York Yankees and Los Angeles Dodgers to newer teams like the Arizona Diamondbacks and Tampa Bay Rays, each team plays a crucial role in the ongoing story of Major League Baseball.
