The 1906 White Sox team became known as the Hitless Wonders when they won the American League pennant despite posting the lowest team batting average in the league. The team had been in fourth place by the end of July, 7½ games behind the defending champion Philadelphia Athletics, when they went on a 19-game winning streak that drove them into first place. No American League team would match the 19-game winning streak for almost 100 years. The team made up for their lack of hitting prowess by leading the league in walks, hit batsmen and sacrifice hits. The White Sox pitching staff had a league-leading 32 shutouts and the second lowest earned run average in the league. The White Sox then defeated their cross-town rivals, the heavily favored Chicago Cubs in the 1906 World Series.
