Recent MLB Pennant Winners
Since 1903, the champion of the American League has met the champion of the National League in the World Series.
Prior to 1969, there were no divisions in either the AL or NL, and the champion (a.k.a. pennant winner) in each league was decided by the regular season standings in each league, or in the event of a tie in the standings, a playoff between the tied teams.
In 1969, MLB expanded from 20 to 24 teams, with two six-teams divisions in each league. Since then, pennant winners have been decided by a playoff system.
In the current playoff system, six teams from each league make the postseason, and three rounds (the Wild Card round, the Divisional round, and the League Championship Series round) are played to determine the pennant winners/World Series matchup.
