The Boston Red Sox are a professional baseball team based in Boston, Massachusetts. The Red Sox are a member of the Major League Baseball's American League Eastern Division. Since 1912, the Red Sox's home ballpark has been Fenway Park. The 'Red Sox' name originates from the iconic uniform feature. The club was founded in 1901, as of the American League's eight charter franchises. They won four more championships by 1918, and then went into one of the longest championship droughts in baseball history, which ended in 2004, when the team won their sixth World Series Championship. Since 2003, the Red Sox have competed in four ALCS, have won two World Series, and have emerged as arguably the most successful MLB team of the last decade.
