Alexander Steen and David Backes had two goals apiece and the St. Louis Blues' defense put the clamps on the Dallas Stars in a 6-1 victory that put them up 2-1 in the second-round series Tuesday night.
Vladimir Tarasenko had a goal and two assists, Troy Brouwer had a goal and assist and Brian Elliott was strong when he needed to be for the Blues in their first lopsided triumph of the postseason. Their other five wins were decided by one goal.
The Blues finished two points behind Western Conference champion Dallas in the regular season and have control of the series heading into Game 4 Thursday night in St. Louis. Despite a late start -- more than 1 1/2 hours past the usual puck drop -- the vast majority of a standing-room crowd of 19,323 stuck around to the finish.
St. Louis scored six unanswered goals after Colton Sceviour gave Dallas the early advantage, three coming in a breakaway second period. Steen capped the big second period with a power-play goal, matching his postseason career high for goals in a game.
Antti Niemi was the lone major lineup change for Game 3, replacing Kari Lehtonen in the Stars' net after playing effectively the last two periods plus overtime in Game 2. That switch didn't last long, and it didn't matter.
Lehtonen was back early in the second after Niemi allowed three goals on 12 shots.
The third period turned nasty when Stephen Johns boarded Alex Pietrangelo with 3:01 to go, leading to a pummeling of Curtis McKenzie by Blues regulator Ryan Reaves. Backes scored his fifth of the postseason during the 4-on-4, giving the captain his first career multi-goal game.
Tarasenko also had a three-point game in the first round against Chicago. He's the first St. Louis player with multiple three-point games in the postseason since Doug Weight also had two in 2003. He has 15 goals in 23 career playoff games.
Sceviour tapped in his own rebound for the Stars' lone goal at 4:44 of the first. Just 1:07 later, Steen tied it on a play that developed off a turnover by Alex Goligoski.
Backes, who got the winning goal on an overtime power play in Game 2, put St. Louis ahead on another power play on a deflection at 16:10.
The Stars just missed a chance to tie it late in the period. Jason Demers' shot off the crossbar was ruled a goal on the ice but was waved off after video review.
The rest was all St. Louis.
Brouwer skated in alone for his third goal of the postseason, Tarasenko scored off Goligoski's skate and Steen scored on a power play.
