Rookie forward Jakub Vrana, 21, who was the No. 13 pick in the 2014 NHL Draft, had two assists while skating on a line with Ovechkin and Kuznetsov.
"I could see them talking and (Kuznetsov) and (Ovechkin) they sort of just said we've got to do something here and the young guy (Vrana) was good, too," Capitals coach Barry Trotz said. "They gave us a little momentum. We needed someone to pick us up and that line picked us up."
Ovechkin scored all three goals in a span of 6:33 in the third period to help the Capitals rally after going down 3-1 and 4-3.
"It's always nice when you have the chemistry like we have," Kuznetsov said. "We understand each other. We were talking to each other. The first period wasn't great, but we stayed positive. I like the way we talk on the ice. Sometimes you don't see your partner, but you hear him. That always helps you. That's why we scored a couple of goals, because we talked before.
