List of World Series champions
The World Series is the annual championship series of Major League Baseball (MLB) and concludes the MLB postseason. First played in 1903, the World Series championship is determined through a best-of-seven playoff and is a contest between the champions of baseball's National League (NL) and American League (AL). Often referred to as the "Fall Classic", 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.
World Series
However, the Baltimore Orioles made three consecutive World Series appearances: 1969 (losing to the "amazing" eight-year-old franchise New York Mets), 1970 (beating the Reds in their first World Series appearance of the decade), and 1971 (losing to the Pittsburgh Pirates, as well their 1979 appearance, when they again lost to the Pirates), and the Los Angeles Dodgers' back-to-back World Series appearances in 1977 and 1978 (both losses to the New York Yankees), as well in 1974 losing against the cross-state rival Oakland Athletics.
