1891 – The American Association passes out of existence after ten years as a settlement is finally reached with the National League. Four AA clubs (St. Louis, Louisville, Washington, and Baltimore) join the National League’s existing eight clubs to form a twelve-club league formally styled “The National League and American Association of Professional Base Ball Clubs.” The other four AA clubs are bought out for about $130,000. The NL will allow Sunday games for the first time but will retain its 50-cent minimum admission price.
