Defenseman Barret Jackman scored on a drive through traffic, giving the St. Louis Blues their second straight 4-3 overtime victory over the Chicago Blackhawks on Saturday for a 2-0 series lead against the defending Stanley Cup champions.

St. Louis rallied after Chicago defenseman Brent Seabrook received a five-minute major and game misconduct penalty for a vicious elbow to the head on Blues captain David Backes, who had to be helped off the ice, went straight to the locker room and did not return for overtime.

Vladimir Tarasenko forced overtime with his second goal of the series, beating Corey Crawford with a wrist shot that banged off the right post and in with 6.4 seconds to go. Kevin Shattenkirk had a goal and two assists for the Blues.
