CHICAGO (AP) -- Duncan Keith had a goal and three assists, and the Chicago Blackhawks used a four-goal third period to finish off the St. Louis Blues with a 5-1 victory in Game 6 of their first-round playoff series on Sunday.
Chicago won four in a row after a slow start in St. Louis. The defending Stanley Cup champions will play the winner of the Minnesota-Colorado series in the Western Conference semifinals. The Avalanche lead the Wild 3-2 heading into Game 6 in Minnesota on Monday night.
Jonathan Toews, Patrick Sharp, Andrew Shaw and Keith scored in the third period as the Blackhawks improved to 14-2 in home playoff games over the last two seasons. Corey Crawford made 35 saves, keeping Chicago in a tie game when St. Louis controlled the second period.
