Luke Evangelista scored, and Juuse Saros made 10 saves for the Predators, who are the first wild card from the West.
Vancouver leads the best-of-7 series 2-1. Game 4 will be here on Sunday.
“That’s the most [offensive zone] possession time we’ve had, the most shots, the most Grade A’s,” Evangelista said. “It all stems from the forecheck, good puck placement. We were able to spend a lot more time down there. Obviously, we had the momentum for most of that game, especially in the third there. If we keep playing like that we’ll be in a good spot.”
Miller gave the Canucks a 1-0 lead on a power play at 13:23 of the first period. Hughes passed the puck over to Miller above the left circle, and he beat Saros glove side with a wrist shot.
“I can’t say enough great things about [Miller],” Vancouver defenseman Ian Cole said. “He’s one of our emotional leaders. He’s one of our elite players that we have, and we’re fortunate to have a lot of them. He’s a guy that everyone looks to lead this team. He gets fiery. He is not afraid to say what’s on his mind, but everyone knows it comes from a place of wanting to win and pushing everyone.”
Brock Boeser made it 2-0 with another power-play goal at 4:33 of the second period. He redirected a centering pass from Miller five-hole on Saros.
Vancouver was 2-for-3 on the power play. Nashville was 0-for-5.
“The timing of that goal, that’s [Boeser],” Canucks coach Rick Tocchet said. “... Obviously, the downhill shot by [Miller], we’ve seen that before. I think it’s huge for our team if our power play can find it.”
