The History of MLB Expansion

To understand how many teams are in the MLB, it’s helpful to look back at its history of expansion. The league, as we know it today, took shape in 1903 with the formation of the National League and American League. For much of the early 20th century, both leagues consisted of eight teams each, totaling 16 MLB teams.

However, the latter half of the century saw significant expansion. The first wave began in 1961 with the addition of the Los Angeles Angels and the expansion Washington Senators (now the Texas Rangers). Over the next few decades, the MLB welcomed several new franchises, including the cali baseball teams like the San Diego Padres and the Oakland Athletics.

The most recent expansion occurred in 1998 with the creation of the Arizona Diamondbacks and the Tampa Bay Rays, bringing the total number of MLB teams to 30.

The Two Leagues and Six Divisions

The 30 MLB teams are divided into two leagues:

  • American League (AL): Founded in 1901, the AL consists of 15 teams.
  • National League (NL): Founded in 1876, the NL also consists of 15 teams.

The Significance of 30 Teams

The number of teams in Major League Baseball, 30, represents a rich history of expansion and a dedication to bringing the sport to fans across North America. This number also holds significance for scheduling and playoffs. With 30 teams, each team plays 162 games in a regular season, facing divisional rivals more frequently than other teams. The top teams from each league then advance to the playoffs, culminating in the World Series, where the American League champion faces off against the National League champion.

FAQs about the Number of MLB Teams

1. Are there any plans to add more MLB teams?

While there has been discussion about potential expansion cities, MLB Commissioner Rob Manfred has stated that expansion is not a priority in the immediate future.

2. Have any MLB teams relocated or changed names?

Yes, throughout MLB’s history, several teams have relocated to different cities, and some have undergone name changes. For example, the Washington Senators moved to Texas and became the Rangers, and the Montreal Expos relocated to Washington, D.C., and became the Nationals.

3. What is the difference between the American League and the National League?

The main difference used to be the designated hitter (DH) rule, where the AL allowed a designated hitter to bat for the pitcher, while the NL did not.
