Expansion Teams in Major League Baseball
Major League Baseball, like many other large sports groups, is a franchisor. What this method is that expansion teams are only additional when they pay to be part of the group, bringing a new city into the mix as a possible champion.
When the league was formed there were only 16 teams, all of which were in the east and St. Louis. But between the leagues inception and today the population of the west has more than doubled. Those residents of Oakland, San Francisco, Denver, Phoenix, LA and other Western cities wanted representation, too. Some eastern teams moved west (SF Giants) but most didn’t want to. What were the cities to do? They got expansion teams.
Expansion teams generally perform terribly during their first few seasons. New teams don’t have the money to bring big names to their cities, and because they are new they have last choice in the draft. What that method is that the handful of new expansion teams are competing against one another to get the best of a average lineup of talent. It is not impossible to succeed within a few years, though: the Arizona Diamondbacks were established in 1998 and they won the World Series in 2001. That said, this is the exception to the rule.
The first two expansion teams were brought in 1961, and the MLB has been seeing additions every few years since then. The most recent additions were in 1998. Today’s team list has gone up from its original 16 to 30.
