After Killorn and Oshie, with the man advantage, traded goals early in the second, Kunitz's redirection cut the deficit to 3-2 with 1:51 left in the period.
"A good building block for our team," Kunitz said.

Vasilevskiy stopped a first-period breakaway by Evgeny Kuznetsov, who got his eighth assist on Oshie's second goal.
"We had a couple chances to make it 4-1 and we didn't," Trotz said. "They just chipped away."
