"It was a battle tonight," Rinne said. "The first two periods, great lead, 3-0. [Colorado's] a good team. They came back and we battled. We did a really good job at the end there. We blocked a few and they missed the net a couple of times. We killed the clock pretty good at the end and did a really good job."
Filip Forsberg, Colton Sissons and Craig Smith scored for the Predators.
"[Colorado's] not going to go anywhere, we're ready for that," Forsberg said. "It's been four really hard-fought games so far and we're looking for another one Friday."
Alex Kerfoot and Gabriel Landeskog scored, and Jonathan Bernier made 23 saves for the Avalanche before leaving the game after the second period with a lower-body injury. He was replaced by Andrew Hammond, who made eight saves.
"Haven't seen [Hammond] a lot, hasn't played a lot, but he's been in twice now and done a good job," Avalanche coach Jared Bednar said. "That's the situation we could possibly be in. I don't know if that's the case just yet. From what I've seen, [Hammond] has been OK."
Forsberg scored to give the Predators a 1-0 lead at 15:33 of the first period. After taking a pass from Ryan Johansen, Forsberg carried the puck into the Avalanche zone, skated around defenseman Duncan Siemens, and scored into an open net after Bernier missed on a poke-check.
"I thought we came out strong," Predators coach Peter Laviolette said. "It was a good response from the game before when I don't think we played very well."
Sissons extended the lead to 2-0 at 7:18 of the second period, scoring blocker side from the right hash marks off a pass from Forsberg.
