Mark Scheifele scored his first of the postseason, Kyle Connor had a goal and an assist, and Neal Pionk had three assists for the Jets, who are the second wild card from the West. Connor Hellebuyck made 43 saves.
"That was a [heck] of a hockey game," Winnipeg coach Rick Bowness said. "The crowd was fantastic. The guys laid it all out there on the line tonight. They played their hearts out. Very proud of the way we played. We're down early, we get that, we fought back. We're down three going into the third and we kept fighting. There is no quit in this group."
Jets defenseman Josh Morrissey left the game with a lower-body injury at 4:34 of the first period. He appeared to sustain the injury in a collision with Zach Whitecloud at 1:43 before playing one more shift on a power play.
"He's got a lower body and he's done for the series," Bowness said. "Now, when we get into next week, I'll be able to give you a better answer (about timeline going forward). I just know he's done for the series."
Nino Niederreiter brought Winnipeg to within 4-2 at 2:04 of the third period with a wrist shot from the right face-off circle.
Scheifele then cut it to 4-3 at 14:08 on a power play, scoring glove side from the top of the left circle.
"The first two periods we didn't quite show it the way we wanted to," Niederreiter said. "That third period, we knew we had to play to our identity to be successful, and that's exactly what happened."
