Regular season
In late April, the Cardinals fired manager Vern Rapp, who had started at 7-11. He was briefly replaced by coach Jack Krol for two games (1-1) before giving the job on a permanent basis to their former MVP third-baseman Ken Boyer, who went 61-81 the rest of the way.

On June 16, Tom Seaver of the Cincinnati Reds made history by pitching a no-hitter against the Cardinals. It would be the only no-hitter of his career.

First baseman Keith Hernandez won a Gold Glove.

This remains to date the only 162-game season in which the Cardinals failed to win at least 70 games.
