Theodore tied it 2-2 at 4:12. The defenseman received a pass from Stone and was stopped on his first two attempts before tucking it in with the backhand on the third.
Carolina outshot Vegas 34-16 through two periods. Lehner stopped all 19 shots in the second period.
"Robin gave us a chance to be in that game. I thought he was our best player again tonight," Vegas coach Peter DeBoer said. "They're a team that slings a lot of pucks to the net from the point, from bad angles, and I think in my time here we've taken a lot of pride in denying those pucks to the net with shot blocks or good sticks and we weren't good in that area tonight."
Jarvis gave the Hurricanes a 3-2 lead at 1:11 of the third off a rebound from Ethan Bear's shot from the right circle.
Trocheck scored off a rebound below the goal line at 13:41 for the 4-2 final.
"Especially in the first and third, I think we really played our game," Jarvis said. "I think in the second we stuck to our game but got away from it a little bit. I think we could've easily had over 50 shots. That's a testament for how we want to play; just put some pucks on the net, especially on face-offs, create a little chaos, and good things happen when you go to the net."
