Perbix gave the Lightning a 4-3 lead at 15:05 after Kucherov skated into the slot and made a drop pass to the defenseman. It was Perbix's ninth NHL game.
"Pretty surreal honestly," Perbix said of his goal. "It's something you always dream of and for it to be a game-winner makes it that much sweeter. I just hopped on the ice, saw we had a rush and tried to make the most of it."
Kucherov scored into an empty net at 19:02 for the 5-3 final, extending his goal streak to six games. He also has a 10-game point streak (19 points; six goals, 13 assists).
"He's a magician out there, so you never know what he's going to do," Hagel said. "He's such a skilled player that you have to be ready at all times."
