Going back to 1905 when the best-of-seven series was implemented, 35 out of 96 World Series have gone to a Game 7 showdown. That's roughly 36% of all World Series.
I'll presume your question is, "How many World Series have gone to seven games over the last ten years." Seven game series occured in 2011, 2002, and 2001.
The first World Series, in 1903, was a best-of-nine Series. There was no world series in 1904, and from 1905 - 1918 the World Series was best of seven. From 1919 - 1921 baseball returned to the best of nine format. from 1922 on the World Series remained the best of seven.
The St. Louis Cardinals won the 2011 World Series by defeating the Texas Rangers in seven games.
It didn't, the World Series in 1919 went eight games with the Cincinnati Reds defeating the Chicago White Sox 5 games to 3. Of course, that was the famous "Black Sox Scandal" after it was discovered that seven White Sox players were bribed to throw the series. The number of games in the World Series varied in the early years and didn't settle in to a best of seven series until 1922.
No. The two championship series are the best 4 out of 7 games. When one of the teams wins 4 games, the series is over. If one team wins the first four games in a row, then only four games are played.
It has never happened in the 100-plus years of World Series competition.
The World Series is a best 4 out of 7 match. The most games that could be played is seven. There were a few years (1903, 1919-1921) when the World Series was a best 5 out of 9 match. In three of those years (1903, 1919, 1921) the Series lasted 8 games.
Derek Jeter has appeared in seven World Series: 1996, 1998, 1999, 2000, 2001, 2003 and 2009. The Yankees won world championships during the years outlined in bold.
The Red Sox have lost four World Series; in 1946 and 1967 against the St. Louis Cardinals, in 1975 against the Cincinnati Reds and in 1986 against the New York Mets. All four World Series were lost in seven games.
Through the 2008 season, the Pirates have played in seven World Series and won five. 1979*, 1971*, 1960*, 1927, 1925*, 1909*, 1903 Years followed by an '*' are years that the Pirates won the World Series.
The Giants have played in the World Series six times since moving from New York to San Francisco in time for the 1958 season. In 1962, they lost to the New York Yankees in seven games. In 1989, they lost to the Oakland Athletics in four games. In 2002, they lost to the then-Anaheim Angels in seven games. In 2010, the Giants finally won a world championship for the Bay Area, defeating the Texas Rangers in five games. They won their second world championship in three seasons by sweeping the Detroit Tigers in the 2012 World Series. Two years later, the Giants' appearance in the 110th World Series resulted in a seven-game victory over the Kansas City Royals of the American League. It was San Francisco's third world championship in five seasons.
The World Series has used a 2-3-2 location plan for many years now.
