MLB does not require teams to make up late season games cancelled due to rain if the outcome of the game will not change the standings. The September 25 game, scheduled against the Chicago Cubs, was cancelled due to rain and was the second game of a two game series. The Cardinals were so far ahead of every other team in the League, at that time by 10 games with only four games left in the season, that it was not necessary to make up the game since they had already clinched the pennant.
