List of World Series champions

[2] Often referred to as the "Fall Classic",[3] the modern World Series has been played every year since 1903 with two exceptions: in 1904, when the NL champion New York Giants declined to play the AL champion Boston Americans; and in 1994, when the series was canceled due to the players' strike.

[1][2][4][5] The best-of-seven style has been the format of all World Series except in 1903, 1919, 1920, 1921, when the winner was determined through a best-of-nine playoff.

[6] Players, coaches and others associated with the team are generally given World Series rings to commemorate their victory; however, they have received other items such as pocket watches and medallions in the past.

[7] The winning team is traditionally invited to the White House to meet the President of the United States.

The New York Yankees of the AL have played in 41 World Series, winning 27 – the most championship appearances and most victories by any MLB team.
