The Boston Red Sox are an American professional baseball team based in Boston, Massachusetts, that competes in Major League Baseball (MLB). They are members of the East Division of the American League (AL). The Red Sox have won 8 World Series, having appeared in 12. Founded in 1901 as one of the American League's eight charter franchises, the Red Sox's home ballpark has been Fenway Park since 1912. The "Red Sox" name was chosen by the team owner, John I. Taylor, around 1908, following the lead of previous teams that had been known as the "Boston Red Stockings", including the forerunner of the Atlanta Braves. Boston was a dominant team in the new league, defeating the Pittsburgh Pirates in the first World Series in 1903 and winning four more championships by 1918. However, they then went into one of the longest championship droughts in baseball history, called by some the "Curse of the Bambino" after its alleged beginning with the Red Sox's sale of Babe Ruth to the rival New York Yankees two years after their world championship in 1918, an 86-year wait before the team's sixth World Championship in 2004. The team's history during that period was punctuated with some of the most memorable moments in World Series history, including Enos Slaughter's "mad dash" in 1946, the "Impossible Dream" of 1967, Carlton Fisk's home run in 1975, and Bill Buckner's error in 1986. Following their victory in the 2013 World Series, they became the first team to win three World Series trophies in the 21st century, including championships in 2004 and 2007. Red Sox history has also been marked by the team's intense rivalry with the Yankees, arguably the fiercest and most historic in North American professional sports. The Boston Red Sox are owned by Fenway Sports Group, which also own Liverpool F.C. of the Premier League in England. The Red Sox are consistently one of the top MLB teams in average road attendance, while the small capacity of Fenway Park prevents them from leading in overall attendance. From May 15, 2003 to April 10, 2013, the Red Sox sold out every home game—a total of 820 games (794 regular season) for a major professional sports record.
