Before the creation of the MLB, the AL and NL were bitter rivals. This was caused when the AL moved its teams to the East Coast with the goal of taking away players that competed in the NL. Finally, in 1903, the National League and American League set aside their differences and converged together to create Major League Baseball.
The MLB season starts around February and March with Spring Training to prep the players for the upcoming season. The regular season starts in April and spans 162 games until the end of September. Teams who qualify for the playoffs begin postseason play in October.
There are 30 teams that compete in Major League Baseball. Below is a list of all 30 MLB teams ordered alphabetically.
The MLB is divided into two conferences, the American League and the National League. Each conference consists of three divisions (West, Central and East) with five teams competing in each division.
Since 1933, the AL and NL also compete in an All-Star game every July where players from each conference are nominated by fans and coaches to play in the game.
At the conclusion of each season, the winner of the AL and the winner of the NL meet in the World Series to play a best of seven series. The AL leads the all-time record with 66 wins to the NL's 48 wins. The New York Yankees currently have the most World Series championships with 27.
