Seguin scored two early goals and the Stars beat the Colorado Avalanche 7-2 on Sunday night for their fifth consecutive victory.
Brett Ritchie also had two goals, and Jason Spezza and Greg Pateryn each added one for the Stars, who haven't lost since a 3-0 setback at Colorado on Nov. 22. Devin Shore scored short-handed into an empty net at 17:24 of the third period. Ritchie closed out the scoring seconds later with his second of the night.
"Tonight, it wasn't just our line, it was the whole team," Seguin said after the Stars set a season high for goals. "It's everybody. It's when you have guys like (Radek) Faksa who has five goals or whatever in the last few games. Not only does that give him confidence, it gives his linemates confidence, it gives everyone else confidence. It's been a domino effect through the lineup."
Dallas coach Ken Hitchcock likes what he's seen during the streak.
"We are playing the right way," he said. "We are not chasing the game up and down the ice. We aren't gambling on 50/50 situations. We are playing smart. You play the game the right way, you give yourselves a chance to win games. That's what we are doing."
Colorado defenseman Erik Johnson said his team made too many mistakes to be competitive against the Stars.
"We gave them everything they got tonight," Johnson said. "We turned the puck over, we were sloppy and there's no excuse. There's no one to blame but ourselves for that one.
"You just have to flush it down the toilet and focus on the next one. We played horrible."
Trailing 2-0, the Avalanche got on the board 39 seconds into the second when Nathan MacKinnon sent a cross-ice pass to Rantanen, who wristed the puck over goalie Kari Lehtonen's glove from the left circle.
Bernier, who made 28 saves in Colorado's shutout win over the Stars two weeks ago, was pulled after Pateryn's goal in favor of Semyon Varlamov. Bernier gave up four goals on nine shots.
Colorado pulled to 4-2 when Comeau knocked in a rebound at 12:45 of the second, but the Stars soon answered with another goal. Ritchie put the puck into an open net after Varlamov drifted to the side to contest a shot from Curtis McKenzie, who corralled the rebound and sent it back to Ritchie for his first goal.
Seguin got the Stars off to a great start, scoring their first two goals in the first period. He picked up a loose puck in the Dallas zone and rushed down the ice, letting loose a backhand from in close that beat Bernier.
