The Cardinals–Cubs rivalry, also called the Route 66 rivalry and The I-55 rivalry, refers to the rivalry between the St. Louis Cardinals and Chicago Cubs of the National League (NL), one of the most bitter rivalries in Major League Baseball and in all of North American professional sports. The Cardinals have won 19 NL pennants, while the Cubs have won 17. However, the Cardinals have a clear edge when it comes to World Series success, having won 11 championships to the Cubs' three. Games between the two clubs see numerous visiting fans in either St. Louis's Busch Stadium or Chicago's Wrigley Field. When the NL split into two divisions in , and later three divisions in , the Cardinals and Cubs remained together. The Cubs lead the regular season series 1,259–1,209–19. The teams' lone MLB playoff meeting occurred in the 2015 National League Division Series, which the Cubs won, 3–1. First meetings in 19th century World Series In his book, Before They Were Cardinals, Jon David Cash speculates that the economic trade rivalry between the cities of Chicago and St. Louis led to the formation of the St. Louis Brown Stockings in 1875 to compete with the Chicago White Stockings. The Brown Stockings would later fold and reemerge in 1882 when the Cardinals (as the Browns), met the Cubs (as the White Stockings), in a pair of pre-World Series matchups between American Association champion St. Louis and NL champion Chicago. First meeting The first series meeting between the two teams was actually played in four cities — not only St. Louis and Chicago, but also Pittsburgh and Cincinnati. On October 15, Browns manager Charles Comiskey pulled his team off the field in the 6th inning in protest of umpire Dave Sullivan's call. The White Stockings were in the lead at the time 5–4 and were declared a winner on forfeit. Behind pitcher Dave Foutz, St. Louis defeated Chicago 13–4 in Game 7. The Browns claimed the Game 2 forfeit didn't count and therefore claimed the championship. The two clubs split the $1000 prize. The $15,000 slide The first series played in 1885 ended in dispute with no winner making the rematch a year later more heated. Game 2 saw the Browns win in a 12-0 romp. Bob Caruthers pitched a one-hitter, and left fielder Tip O'Neill smacked two inside-the-park home runs. It was the first two-home-run game by a player
