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.
2011 Major League Baseball season
The 2011 Major League Baseball season began on Thursday, March 31, and ended on Wednesday, September 28. This marked the first time a season began on a Thursday since 1976, and the first time a regular season ended on a Wednesday since 1990. The 82nd edition of the Major League Baseball All-Star Game was played at Chase Field in Phoenix, Arizona, on July 12 with the National League defeating the American League for the second straight year, by a score of 5–1. As has been the case since 2003, the league winning that game has home field advantage in the World Series. Accordingly, the 2011 World Series began on October 19, and ended on October 28, with the St. Louis Cardinals winning in seven games over the Texas Rangers.
