A change was made yesterday in the Union Association schedule, so that the games the St. Louis Unions were to have played the Cincinnatis here on Sunday, Monday, Wednesday and Thursday next will be played on Saturday, Sunday, Monday and Tuesday next. The change is made so as not to clash with the opening dates of the St. Louis Jockey Club.-St. Louis Globe-Democrat, June 4, 1884
One day I'm going to have to write something about how popular horse racing was in St. Louis. It goes back to the founding of the city and the first French settlers in the city. Those folks loved their horse racing and the tradition carried on throughout the 19th century.
