Blake Wheeler and Tyler Myers scored for Winnipeg. Connor Hellebuyck made 16 saves on 22 shots and was replaced for the third period by Steve Mason, who made seven saves.
"It's one game in a seven-game series," Wheeler said. "We didn't play anywhere near our level tonight. … We need to play with team speed, like we were able to accomplish the second half of both Games 1 and 2. (At) 2-1, they came out extremely hard, it's not a death sentence by any means in this building. But when that second period started, we weren't able to get faster. And that's when the game changed. They stuck with it, and we just weren't able to get to our speed we needed to get to."
The Wild broke the game open with three goals in 3:43 in the second period. Staal scored his first goal of the playoffs at 14:40 to make it 4-2. Greenway scored 20 seconds later to make it 5-2, and Foligno increased the lead to 6-2 at 18:23.
"Well, I think everybody knows if we lose Game 3 how difficult it is," Wild coach Bruce Boudreau said. "Especially playing these guys. We didn't want to get down 0-3. I think desperation is the best word. When we're down 0-2 it's still a big hurdle. They will be a lot better next game."
The Jets arrived in Minnesota early Sunday morning because of a blizzard. They were scheduled to arrive Saturday afternoon, but after a flight delay and a detour, they flew back to Winnipeg.
