Winnipeg now sits atop the Central Division standings with an 8-3-1 record.
The Jets swept a three-game homestand and have won six of their last seven games, their only blemish an overtime loss to the Vegas Golden Knights on their last road trip.
“We’re just comfortable playing our game. We’re not sitting back on our heels, we’re playing on our toes, we’re making it hard on teams to make plays and make continuous passes. That comes with playing fast and having good sticks and trusting your teammates. I think we’ve done a really good job with that," said Scheifele.
Scheifele was a part of a second period offensive explosion for the Jets, who broke the game open with three tallies in a 2:45 minute span.
The Jets fired four goals in the second stanza after a scoreless first period.
Mason Appleton had a goal and two assists for Winnipeg.
Pierre-Luc Dubois and Saku Maenalanen also scored for the Jets.
Kyle Connor had three assists for the Jets.
Connor Hellebuyck made 21 saves for Winnipeg.
Jason Robertson scored for the Stars, who finished a three-game road trip with a loss.
Scott Wedgewood turned aside 28 shots as Dallas, who dropped to 8-4-1.
There was no scoring in the first period.
Jason Robertson broke the stalemate just over three minutes into the second when he snagged a loose puck off of Neal Pionk's skate in the slot and beat Hellebuyck with a blocker side wrister to make it 1-0 Stars.
The goal was his 9th of the season.
Mark Scheifele replied 21 seconds later when he finished off a nifty three-way passing play off the rush, burying a cross-crease Mason Appleton feed to get the Jets on the board.
Pierre-Luc Dubois gave Winnipeg the lead at 4:37 when he found himself in front of a wide open net after Dallas goaltender Scott Wedgewood had a miscue behind the Dallas goal.
Blake Wheeler got his stick on the puck and got the puck to Cole Perfetti who relayed it to a wide open Dubois.
Dubois lifted a backhand shot into the net to make it 2-1 Jets.
The goal was his 6th of the season.
Scheifele potted his second of the night at 6:12.
Kyle Connor got control of the puck behind the Stars goal and worked himself into the high slot before curling hard toward the left boards and accelerated before hitting Scheifele with a cross crease feed which he tapped past Wedgewood to make it 3-1 Jets.
The goal was his 8th of the season.
Saku Maenalanen got his stick on a Neal Pionk shot late in the second period to give the Jets a 4-1 lead at 18:14.
The goal was his first as a Winnipeg Jet.
Mason Appleton scored an empty netter with just under three minutes left in regulation to seal the win for the Jets.
The game was an early season first place showdown.
But that mattered little to Appleton.
“It’s big time. When I was traded back here at the end of last year, there was a couple of meaningless hockey games, you were just playing for your pride. Those games aren’t near as fun as playing for first place, no matter if that is Game 12 or Game 75. We love where our game is at right now, and to be in first place feels damn good," he said.
Jets Head Coach Rick Bowness says his club is starting to see the fruits of their labours.
“I see a more confident team. They understand if they play the right way and do these things that we keep preaching, we’re going to have success. We are going to cut down on the chances against, the shots against and we are going to have a lot more fun when we get the puck. I think that they are starting to see it. They should see it. They’re playing like they see it. The confidence is there right now," said Bowness.
Stars Head Coach Pete DeBoer said his club just wasn't good enough.
"I thought we had a really poor first period. I thought we kind of regrouped at the beginning of the second, scored the first goal, started to play and then you know just some poor decisions and some poor execution for five or six minutes and we lost all of our momentum and you know the game was essentially over at that point."
Dallas returns home to host San Jose Friday while Winnipeg visits Calgary on Saturday.
NOTES-Winnipeg gave up only one man advantage on the night, a third period tripping penalty by Kyle Connor.
The Jets four goal second period outburst was a season high.
Winnipeg has not allowed a third period goal for six straight games.
