Scheifele one-timed a shot from the top of the left face-off circle for his first goal of the season.
"It was a great pass by [Nikolaj Ehlers]," said Scheifele, who played his ninth game. "It felt good to end that one. It was a grind of a game, and we started to pick our game up toward the end of that third period and play a little more grinding style. You need to be able to pull those ones off in this league."
Connor Hellebuyck made 27 saves for the Jets (8-3-3), who are 4-1-1 on a seven-game homestand that concludes Tuesday against the Edmonton Oilers.
Dylan DeMelo scored shorthanded to tie the game 2-2 at 13:36 of the third period, ending a 132-game goal drought that dated to March 21, 2019, while he was playing for the Ottawa Senators.
"You play [defenseman], you're not maybe relied on to score but you want to contribute, and there's no feeling like scoring," DeMelo said. "It was nice to get that one, and the timing was crucial, and to be able to contribute in that sense it feels really good. I don't do it often so I'm happy to contribute and get a big goal for us."
