It is made up a many different teams which play in many leagues and levels of ability. Minor league teams are used by Major League teams to have a place to put their players who they do not feel are good enough to play in the Major League yet.
There are several different levels of ability in the Minor Leagues, these levels are (in order from lowest to highest):
- Rookie League
- A-Short Season
When a normal player is first drafted or signed by a major league team, he is usually placed in "Rookie" League or short season A, however top prospects often start higher. If a player plays good in his league he can be "called up" to the next league. If a player does not play well he may be sent back down or cut from the team. This continues until a player gets to the major leagues, although most players never make it that far. This way players are able to get better at baseball before having to play against tougher opponents.
Almost all players in the Major Leagues had to play in the minor leagues first in order to become good enough to play in the Major Leagues Most players spend between 4-5 years before being called up. However, really good players can be called up in less than a year, while some take more than 10 years to reach the majors..
Sometimes, Major League players who are have been hurt will play a few games in the minor leagues before playing in the Major Leagues again, in order to see if they feel good enough to start playing again.
There are also other professional baseball leagues that Major League teams do not use to as a place put their players. These are known as "Independent Leagues". In these leagues players do not go to higher or lower levels of ability.
Minor league teams generally play in cities that are too small for major league teams. City size usually increases with league level.
