Vatrano gave the Ducks a 1-0 lead at 4:49 of the first period, redirecting Ilya Lyubushkin's point shot five-hole on Blackwood. It was his 10th goal of the season.
"When we're breaking the puck out and we're going up the ice as a group, I think that's when we're creating our offense," Vatrano said.
Kunin tied it 1-1 at 13:05. Gibson stopped Hertl's initial backhand in front, but Kunin batted the rebound into the net from the edge of the crease.
Kunin said he's been benefitting from playing on the same line as Hertl and William Eklund.
"Those guys are obviously great players, create a lot of offense," Kunin said. "Just trying to get to the net, create space for them."
Vatrano responded for Anaheim to make it 2-1 at 18:22 of the first, scoring with a one-timer from the top of the right circle on a power play.
"Frankie is an easy guy to coach because he's a high-energy guy. He's got a very high standard for self-accountability, so when you're trying to coach players to a level they're not comfortable playing at, he's an easy guy to push himself to those zones," Ducks coach Greg Cronin said. "Frankie's DNA is to play at that level all the time."
