The Chicago Cubs are a Major League Baseball team and a member of the National League Central Division. One of the charter members of the National League, the club first started playing games in 1870. The Cubs won back-to-back World Series titles in 1907 and 1908. Known by many as "The Lovable Losers," the Cubs' streak without a championship was the longest in baseball history. The Cardinals and the White Sox are the Cubs' main rivals. Ernie Banks, Ron Santo, and Ferguson Jenkins are considered the best players in franchise history.
