The World Series has been played since 1903, with no series played in 1904 and 1994. Until 1969, the World Series was played between the teams in each league that had the best win/loss record. From 1969 to the early 2010s, the MLB expanded to include a league-championship series, divisional series, and a wild-card game. The winner of the World Series is awarded the Commissioner's trophy, pictured right. As of 2025, the most World Series won are 28 by the New York Yankees, 11 by the St. Louis Cardinals, and 9 by the Oakland Athletics.
