Following the season, Major League Baseball announced plans to split both the National and American Leagues into East and West divisions starting with the 1969 season in order to accommodate the inclusion of two new franchises to each league. The Cardinals were assigned to the new National League East division. Originally, the Cardinals were placed in the National League West division. However, the New York Mets, wanting to compensate for the loss of home games against the Los Angeles Dodgers and San Francisco Giants, desired three extra games against the Cardinals, the two-time defending NL champions. The Cardinals were thus moved to the National League East division along with the Chicago Cubs, who wished to maintain their long-standing rivalry with the Cardinals. The Atlanta Braves and Cincinnati Reds were correspondingly shifted to the National League West despite both being east of St. Louis and Chicago, a configuration maintained until 1993.
