AnonymousIt started in 1922 when both the Cards and Browns were competing for the pennant in their respective leagues. Both the Giants and the Yankees made trades late in the year, I am thinking August, that helped both teams clinch the pennant, thus depriving the world of an all St. Louis series. They complained mightily, I think Branch Rickey had the most influence, and the deadline came to be the next year.
