The 1906 World Series featured a crosstown matchup between the Chicago Cubs, who had posted the highest regular-season win total (116) and winning percentage (.763) in the major leagues since the advent of the 154-game season; and the Chicago White Sox. The White Sox, known as the "Hitless Wonders" after finishing with the worst team batting average (.230) in the American League, beat the Cubs in six games for one of the greatest upsets in Series history. This was the first World Series played by two teams from the same metropolitan area. (The home teams alternated, starting with the NL team being home in Game 1.)
