World Series

World Series, in baseball, a postseason play-off series between champions of the two major professional baseball leagues of North America: the American League (AL) and the National League (NL).

The World Series began in 1903 after the cessation of hostilities between the NL and the newly formed AL. Boston (AL) defeated Pittsburgh (NL) five games to three in a best-of-nine-game series. Attendance was just over 100,000, and the players’ shares of receipts were slightly more than $1,000 each. In 1904 the New York Giants (NL) refused to play Boston, again the AL champion; but the series resumed in 1905 and continued annually until 1994, when a prolonged players’ strike forced its cancellation that year. A seven-game format has been standard since 1922. Beginning in 1955, one player has been voted the Most Valuable Player of each series, a great honour in baseball. Montreal and Toronto were granted major league teams in 1969 and 1977 respectively—the first Canadian teams in major league baseball; Toronto’s World Series win in 1992 was the first victory for a non-U.S. team. The New York Yankees of the AL have won the most series.

The World Series name has been applied to several baseball championships of lesser import, including the Junior World Series, played between champions of the International League and the American Association (both American professional minor leagues), and the Little League World Series, an annual event with international representation for teams of boys and girls 9 to 18 years old.

National League (NL)

National League (NL), oldest existing major-league professional baseball organization in the United States. The league began play in 1876 as the National League of Professional Baseball Clubs, replacing the failed National Association of Professional Base Ball Players. The league’s supremacy was challenged by several rival organizations over the years, beginning with the American Association in 1882–91. Of these, only the American League, formed in 1900, survived. Beginning in 1903, the champions of the National and American leagues have engaged in an annual World Series contest to decide the championship of Major League Baseball. The National League consists of 15 teams aligned in three divisions. In the NL East are the Atlanta Braves, Miami Marlins, New York Mets, Philadelphia Phillies, and Washington (D.C.) Nationals. In the NL Central are the Chicago Cubs, Cincinnati Reds, Milwaukee Brewers, Pittsburgh Pirates, and St. Louis Cardinals. In the NL West are the Arizona Diamondbacks, Colorado Rockies, Los Angeles Dodgers, San Diego Padres, and San Francisco Giants.

American League (AL)

American League (AL), one of the two associations in the United States and Canada of professional baseball teams designated as major leagues. It was founded as a minor league association in 1893 and was initially called the Western League. The Western League changed its name to the American League of Professional Baseball Clubs after the 1899 season, declared itself a major league in 1901 (the year now recognized as the league’s first official season), and was granted equal status by the older National League in 1903. The American League consists of 15 teams (including one Canadian team) aligned in three divisions: the AL East, comprising the Baltimore Orioles, Boston Red Sox, New York Yankees, Tampa Bay Rays, and Toronto Blue Jays; the AL Central, comprising the Chicago White Sox, Cleveland Indians, Detroit Tigers, Kansas City Royals, and Minnesota Twins; and the AL West, comprising the Houston Astros, Los Angeles Angels of Anaheim, Oakland Athletics, Seattle Mariners, and Texas Rangers.
