 joined the National League: i.e., each league each added a fifteenth team. An odd number of teams per league meant that at least one team in each league would have to be idle on any given day, or alternatively that odd team out would have had to play an interleague game against its counterpart in the other league. The initial plan was to have 3 five-team divisions per league with interleague play year-round—possibly as many as 30 interleague games per team each year. For various reasons, it soon seemed more practical to have an even number of teams in both leagues. So, the Milwaukee Brewers agreed to change leagues, moving from the AL Central to the NL Central. (This was the first time since the 1890s that a team had moved from one major league to another.) At the same time, the Detroit Tigers shifted over to the AL Central,making room for the Devil Rays in the East.) After the Houston Astros move to the AL West in 2013, the leagues will once again each have 15 teams.

For the first 96 years, American League teams faced their National League counterparts only in exhibition games or in the World Series. Beginning in 1997, interleague games

 have been played during the regular season and count in the standings. As part of the agreement instituting interleague play, the designated-hitter rule is used only in games where the American League team is the home team. Through the 2011 season, the Yankees have won the most American League pennants (40), followed by the Athletics (15), Red Sox (12), and Tigers (10). Likewise, the Yankees have also won the most World Series (27), with the Athletics second in the American League with nine, the Red Sox third with seven, and the Tigers fourth with four.
