The Texas Rangers are a professional baseball team in Texas, representing the Dallas-Ft.Worth metropolitan area. The Rangers are a member of the Western Division of Major League Baseball's American League. From 1994 to the present, the Rangers have played in Rangers Ballpark in Arlington, located in Arlington, Texas. The "Rangers" name originates from the famous law enforcement agency by the same name.
An expansion franchise, the club was founded in Washington, D.C., in 1961 and was called the Washington Senators (not to be confused with the Washington Senators team that exited D.C. after 1960 to become the Minnesota Twins). The team then moved to Arlington in 1972 and became the Rangers.
