The St. Louis Brown Stockings joined the newly formed National League as a charter member in 1876. They finished the season in a tie for second place, 6 games behind the pennant-winning Chicago White Stockings. Although Chicago won the pennant at the end of the season, St. Louis had won its division series against Chicago 6 games to 4 - winning all of its division series against all National League opponents. Due to the politics between the teams at the time, an unofficial five-game post-season was created between the two teams to determine the "Championship of the West." St. Louis won the series 4 games to 1.
