When a normal player is first drafted or signed by an MLB team, he is usually placed on a Complex League team, however more advanced players may start higher. If a player plays good in his league, he can be promoted or "called up" to the next league. If a player does not play well, he may be sent back down or removed 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 MLB had to play in the minor leagues first to become good enough to play in the major leagues. Most players spend four to five years in the minors before making it to MLB. However, skilled players can be called up earlier, while some may take more than 10 years to reach the majors.
