Mikko Rantanen scored, and Alexandar Georgiev made 19 saves for the Avalanche, who are the No. 3 seed from the Central.
“I felt like we carried some long stretches of the game for the first 40 minutes. My one take would be we’ve got to make it a little bit tougher on Oettinger, getting traffic there,” Colorado coach Jared Bednar said. “We had a couple of really good looks in the first and didn't do it. We had a couple of really good looks in the second and next thing you know, we're down by one.
“Just kind of feels like we push, push, push and then we make one mistake and it ended up in the back of the net in the second, which is unfortunate. But you can’t make those mistakes against Dallas because they have the ability to [capitalize].”
Stankoven gave Dallas a 1-0 lead at 18:39 of the first period on a wrist shot from the left face-off circle that went past the arm of Georgiev. It was the rookie’s first career playoff goal.
“I think it’s always nice to contribute. I feel like I’ve been doing the right things but just couldn’t find the back of the net,” Stankoven said. “There’s always bumps in the road being a young guy in the League, so I’m just trying to find my way and earn the coaches’ trust.”
Rantanen tied it 1-1 at 10:24 of the second period on a rebound of Nathan MacKinnon’s shot in the crease. MacKinnon deked around Stars defenseman Chris Tanev and put his shot off the leg of Evgenii Dadonov.
“I thought we did a lot of great things. We really had a lot of chances, a lot of good looks,” MacKinnon said. “Just Oettinger was great, and we made a couple of big errors that cost us.”
Seguin put the Stars back ahead 2-1 at 15:13 when he deflected a cross-ice pass from Dadonov at the far side of the net.
“We knew coming into this rink how these guys play. We also know how we play on the road,” said Seguin. “We knew it’d be a big challenge. I think next game’s going to be an even bigger challenge, but playoffs are about those moments and getting the right bounces at times as well, and we had that tonight.”
