Stamkos gave the Lightning a 1-0 lead with a power play goal at 6:18 of the first period, scoring with a one-timer from the top of the left face-off circle.
Neal Pionk tied it 1-1 at 4:44 of the second period, redirecting Brenden Dillon’s point shot from the high slot.
“It’s about time he found me,” Pionk said jokingly of Dillon’s slap pass. “Honestly, we made eye contact in the corner and I said, ‘This might happen,’ and I actually got a piece of it and it went in. I couldn’t believe it.”
Alex Iafallo put Winnipeg in front 2-1 at 9:13 when he collected a rebound in the slot from a Cole Perfetti shot and scored with a wrist shot.
Nikolaj Ehlers extended it to 3-1 at 15:13 of the third period. Vasilevskiy attempted to clear the puck, but it was intercepted by Namestnikov, who set Ehlers up for a one-timer from the hash marks.
“He’s the best in the world, and everyone’s going to make mistakes and he’s the first one to admit [it],” Hedman said of Vasilevskiy. “But we trust him 110 percent, and he’s the best in the world for a reason. He’s proven it year in and year out and everyone is allowed to make mistakes.”
