Minor League Affiliates
The concept of an affiliate is not unique to Major League Baseball (Hockey and Basketball also have affiliated minor teams). However, baseball certainly takes the concept to a different level. Minor League Baseball is divided into Full Season and Short Season with full season beginning near the same time as MLB and ending in early September. The short season begins in late June, after the draft. Each "season" is also broken into sub-levels. AAA is the highest and contains mostly older players and more advanced players. This is followed by AA, Advanced A and "A Ball". The short-seasons are divided into "Lo A" and Rookie ball. Though the Mexican League is considered to be AAA calibre, the league is unaffiliated to teams though there is some player movement between affiliated teams and the Mexican League.
Not all MLB organizations, historically, will have teams at all levels though these days, most do. In general, each org has about 6-9 teams in their minor league system, including sometimes multiple teams in the Dominican Summer League which is essentially the starting point for many latin-american players not residents of the US or Canada.
A couple of other affiliate scenarios are teams sharing 1 affiliate or a team in a league with affiliated teams is itself, not affiliated and operates as an Indepedent League Team. An example would be the Miami Miracle of the Florida State League in the early 1990s.
