Pettersson tied it 2-2 during a 4-on-4 situation just 53 seconds into the second period, using an Ilya Mikheyev screen to handcuff Lankinen with a wrist shot from between the top of the face-off circles that trickled in under his blocker.
He scored again under Lankinen’s blocker at 16:38 to make it 3-2 on the power play, this time using a Brock Boeser screen on a wrist shot from the right circle.
Vancouver went 1-for-3 with the man-advantage; Nashville was 0-for-4.
“(Special teams) was huge,” Sissons said. “We've had a few games this year where the special teams was the difference. We've been pretty solid 5-on-5. We’ve definitely got to continue to get better at certain details of the game.”
J.T. Miller, who was benched in the second period after his third penalty, knocked in a rebound during another 4-on-4 situation at 4:11 of the third period to make it 4-2. It was his fifth goal of the season.
“It makes everybody know they're accountable,” Tocchet said. “Some guys get a little longer leash. … I'm not going to sit him in the third period. He's done too many good things for me and his teammates, and when he scored his teammates were so happy for him.”
Pettersson completed the hat trick with an empty-net goal at 17:02 for the 5-2 final.
