The Stars lead the best-of-7 series 2-1. Game 4 is in Denver on Saturday (9:30 p.m. ET; Victory+, MAX, truTV, TBS, ALT, SN, TVAS).
Jamie Benn also scored, and Rantanen had an assist for Dallas, which is the No. 2 seed from the Central Division. Jake Oettinger made 27 saves.
“Gutsy win,” Dallas coach Pete DeBoer said. “You go in after the game and you want to acknowledge some of the key guys and key plays, and really, I could’ve gone around the room. Everybody jumped in tonight and did their part. I thought we worked for a win, did a lot of really good things.
“‘Otter’ was great. It started last game. I thought he got better as the game went on as the heat turned up in the game. He got better last game, and he did the same tonight. That’s not an easy game for him to play in.”
Colorado captain Gabriel Landeskog played in his first NHL game in almost three years, recording a team-high six hits and winning one of two face-offs in 13:16 of ice time. The 32-year-old forward hadn’t played since June 26, 2022, when he had an assist to help the Avalanche defeat the Tampa Bay Lightning 2-1 in Game 6 of the Stanley Cup Final to win the Cup.
“I felt pretty good; speed-wise, legs, physically, I felt good,” Landeskog said. “It felt great in all areas tonight, in terms of just being back, and then on the ice, play-wise, there's areas to improve. But very special night, regardless of the outcome, and looking forward to Saturday already.”
Valeri Nichushkin scored, and Sam Malinski had an assist in his first NHL playoff game for the Avalanche, who are the No. 3 seed from the Central. Blackwood made 26 saves.
“We knew it wasn't going to be easy -- we're playing one of the top teams in the League,” Colorado coach Jared Bednar said. “That's what you can expect. Not a lot of room out there on either side of it, right? Someone's got to make and have an exceptional effort, five guys all on the same page, everyone doing the right thing, and then you still got to be able to beat their coverage in order to create scoring chances.
“The reality of it is it's the first team to four (wins), and we're still in the series.”
