Mercer made it 1-0 Devils at 7:56 of the first period, finding a Nico Hischier rebound at the side of the net and pulling it around Grubauer’s pad.
Larsson tied it 1-1 at 15:47, sending a wrist shot from the top of the left circle through traffic, off the right post and in behind Markstrom.
“We withstood [New Jersey’s early pressure],” Seattle coach Dan Bylsma said. “And then you get a chance to battle back your own way, which I think we did.”
Cotter scored at 19:35 of the second period to make it 2-1 Devils. He won a race to a loose puck and mishandled it, but it rolled through Grubauer’s five-hole and in.
“I tried to go backhand toe drag, but I kind of aborted mission after I was going a little faster than I thought,” Cotter said. “But, I mean, [that’s] the stuff that’s going to go in. So, I kind of had a drought there for a while, and now they’re going to come in bunches. Those are the types that I missed out on before that are coming now.”
