Heiskanen extended the lead to 3-0 at 15:54 with a power-play goal when his shot from the top of the left circle deflected in off Colorado forward Andrew Cogliano’s stick.
“It just seems we weren’t skating enough with the puck and we weren’t getting separation from them. They were doing a good job checking,” Cogliano said. “We have to support the puck a little bit better, we have to get our legs moving and get more of a north game with our legs and our skating. I think a combination of both probably is what didn’t help us in the first period and put us behind.”
Tyler Seguin scored short-handed to make it 4-0 at 18:06, collecting a rebound in the slot and beating Georgiev with a snap shot.
“It felt like a lot of those goals were on us. Just unfortunate they just kind of keep compounding like that early in the game and then we've got to dig ourselves out of the hole,” Colorado defenseman Cale Makar said. “Not [an] ideal way to win games but there was a lot of compete in that third period, so you've got to take that as a positive.”
Kiviranta cut it to 4-1 at 4:06 of the third period, stuffing in a rebound at the right post.
“Some of the breakdowns we did in the third we didn’t do in the first two periods. We got away from that,” Dallas forward Jason Robertson said. “With a team like that, it’s a quick strike. We saw that in Game 1. We have to keep those details throughout the game and try to limit those 5-on-5 chances.”
