Barret Jackman's goal a little over five minutes into overtime lifted the Blues to a 4-3 win and 2-0 lead over the Blackhawks at the Scottrade Center in opening round of the NHL playoffs. Vladimir Tarasenko scored a power play goal with just under seven seconds left in the third period sent the game to the extra session. That goal came as a result of Brent Seabrook's five-minute major and subsequent game misconduct for charging David Backes, who did not return. Backes was crushed into the boards. St. Louis won Game One in triple-OT. Ryan Miller stopped 25 of the 28 shots he faced in the victory. Seabrook, Duncan Keith, and Michael Rozsival each lit the lamp in the loss for the 'Hawks. Corey Crawford gave up four goals on 31 attempts. Game Three is in Chicago on Monday.
