The 1886 World Series was won by the St. Louis Browns (later the Cardinals) of the American Association over the Chicago White Stockings (later the Cubs) of the National League, four games to two. The series was played on six consecutive days running from October 18 to October 23 in Chicago and St. Louis. The series was decided in extra innings of game 6 by Curt Welch's so-called "$15,000 slide" following a passed ball. The decisive run scored by Welch became one of the most famous plays in the history of baseball in that era.
