Washington called a timeout after Barzal's goal to settle themselves. The first period was bookended with power play chances for the Islanders. As the Isles began the second period on their second man advantage of the outing, their sway of the game soon slipped.
"Their top players were their top players tonight," Head Coach Barry Trotz said. "We didn't have enough push back, but we got through that period. It was 2-0 and we got the timely saves by Varly. The second period, we got a power play to start, but then we took unnecessary penalties. That gave them some momentum. They got back on track and then, it was a one-shot game after that."
An onslaught of penalties exchanged between teams in the second period derailed any five-on-five rhythm and allowed the Caps to do their damage, scoring a pair of goals 1:54 apart.
While the Islanders survived an initial 5-on-3 disadvantage, they allowed the first of the Capitals two goals to come four-on-four. With Barzal was serving his penalty for holding on Lars Eller 1:29 into the period and T.J. Oshie was in the box for hooking on Pageau at 3:09, Kuznetsov turned the jets on as he entered the Isles zone. The Caps forward caught the Isles flat footed before he tucked the puck on the far side of Varlamov's net 3:35 into the period.
