Pacioretty forced a turnover by Wild rookie Kirill Kaprizov and finished off a 2-on-1 with Mark Stone after Alex Tuch tied it 4-4 with 42 seconds remaining in the third period.
"Those were some old legs chasing the rookie for a while. I thought I might have puked if I had to skate up the ice again," said Pacioretty, who was on the ice for the final 1:19 of overtime. "Luckily, [Stone] with the strong stick was able to steal it, I saw that [Jordan Greenway] fell, and I knew [Stone] was going to feel that and that there'd be a chance for a 2-on-1 break."
Stone had an NHL career-high five assists, all primary, and Pacioretty had two goals and an assist for the Golden Knights (13-4-1), who have won three straight. Marc-Andre Fleury made 26 saves.
"I think all the goals, guys were getting into good spots," Stone said. "Just waiting for them to make the plays. Those are hard plays."
Marcus Foligno had two goals and an assist, and Cam Talbot made 34 saves for the Wild (12-6-1), who had their six-game winning streak end.
"I thought we played a really good game," Minnesota coach Dean Evason said. "Obviously, there's waves in a game and momentum shifts. We both know what's expected from each other. It's going to be fun going forward playing against this group."
