The Boston Red Sox are a professional baseball team based in Boston, Massachusetts, and are the reigning World Series Champions. The Red Sox are a member and current champions of both the Major League Baseball’s American League Eastern Division and of the American League itself. From to the present, the Red Sox have played in Fenway Park.
