In 1876 in Cincinnati, Ohio, Major League Baseball was born. Fast forward 100 years later, and MLB has become one of the most popular sports in America, and indeed the world.
Things have changed drastically since its inception, and throughout the years, a multitude of players have taken to the fields to play the game.
So, who are the active MLB teams today, and who are their players?
How Many Players Make An MLB Team?
Each Major League Baseball (MLB) team is made up of two rosters – a 25-man and a 40-man.
The 25-man roster is the main MLB team that goes on to play major games, and all players that make up this roster are on a major league contract.
The 40-man roster is composed of the 25-man roster, plus the remaining 15 players (minor league players) or players that are on injured reserve.
Anyone who makes up this roster can be called to play on the main 25 roster.
How Many MLB Teams Are There?
There are 30 MLB teams, and these are divided into several categories: American League Central, American League East, American League West, National League Central, National League East, and National League West. Each of these categories is comprised of five teams.
Below, we’ll take a closer look at the teams in each subdivision and explore their history and some of the most important facts you need to know.

The Old And New MLB Stadiums
To date, the newest MLB stadium is the Globe Life Field, famously the home of the Texas Rangers in Arlington.
The oldest MLB stadium was opened for the 1912 season, and it’s the home of the Boston Red Sox – Fenway Park, Massachusetts.
Although Fenway Park is the oldest MLB stadium in existence, it’s closely followed by the home of the Chicago Cubs, Wrigley Field, which opened in 1914.
MLB Stadium Seating Capacity
Despite MLB attendance declining, the seating capacity of some of its most infamous stadiums just goes to show how popular the game once was and still is.
The Dodger Stadium in Los Angeles, California, has the most seating capacity of any MLB stadium, with the capacity to seat approximately 56,000 fans.
The MLB stadium with the lowest seating capacity is Tropicana Field in St. Petersburg, Florida – the Tampa Bay Rays home.

Los Angeles Dodgers: $4.07 billion
Boston Red Sox: $3.9 billion
Chicago Cubs: $3.8 billion

The Bottom Line
Since its inception, MLB has gained significant momentum, and it has fast become one of the most popular sports in the world.
With roughly 30 teams still packing out the stadiums every game, there’s no indication that our love for MLB is going away anytime soon!
People who say baseball is a boring sport are not playing it correctly. Don’t listen to those people. Instead, listen to me – baseball is awesome!
Hey, my name is Matt Crouch and I have been playing baseball since I could walk. Literally – my parents would take me to the local park and teach me how to throw a baseball around. That set the precedent for my childhood.
