Sportsman's Park I

From BR Bullpen

The first Sportsman's Park in St. Louis, MO was first used for amateur baseball games in 1866. It was home to the St. Louis Brown Stockings of the National Association in 1875, and then by the team of the same name in the National League's original season of 1876 and in 1877. After the Brown Stockings left the league, the Indianapolis Blues used the site for three games in July 1878. It was also known as Grand Avenue Park or the Grand Avenue Grounds.

Sportsman's Park II and the 20th Century Sportsman's Park were both built on the same site, meaning that high-level baseball was played on a single site for 101 years.
