Washington wasn't able to muster a shot on net in either of its first two power plays of the first frame, though it did move the puck around the zone more efficiently on the second of those man advantages.
The third time was the charm.
Most of the players on both sides were engaged in a spirited puck battle along the right-wing half wall in Carolina ice. John Carlson got hold of it, nudging it to the right point where Jakub Vrana was alertly filling in for him. Vrana played the part that Carlson and Mike Green and Dmitry Orlov have played so well over the years, sliding it over to Ovechkin, who launched a shot from above the left circle - so, maybe just outside the door of his office. The shot eluded Mrazek, doubling the Caps' advantage to 2-0 at 17:18.
"Against that team, penalties are not great to take," says Canes captain Jordan Staal. "The first period, we weren't ready to go. And if we're not ready to go, we're going to start taking penalties; we're not moving our feet and we're too slow to pucks. It showed, and 2-0 was all it took. It was an easy game for them after that."
In the second, the penalty pendulum swung in the opposite direction, and Washington found itself killing three minor penalties in a span of less than seven minutes. The Caps spent much of the first half of the middle frame killing penalties and fending off the Canes, and Samsonov made 10 of his 23 stops in the second, six of them coming while the Canes had an extra man. Washington didn't have a shot on net for more than 16 minutes at the start of the second, but it finished the period strong after navigating its way through the penalties.
Early in the third, the Canes took a couple of minors in short succession, giving the Caps 45 seconds worth of time with the two-man advantage. But despite calling timeout to talk it over and winning the offensive-zone draw, the Caps weren't able to threaten in that situation, and they needed Samsonov to make a stop on Carolina's Sebastian Aho while they were still two men to the good.
The Caps stayed disciplined in the third, whittling time off the clock and holding the Canes to seven shots while posting their first shutout in more than 10 months, since Braden Holtby blanked the Devils here last March 8.
"It was important for me," says Samsonov of his first shutout. "Thank you, all team. We played really well; great [penalty kill]. Awesome job, every guy is blocking shots. Great game."
The performance was certainly more to the Capitals' identity than most recent contests. They were assertive, diligent and detailed in all three periods and through all three zones, and the payoff was two points.
"We had more energy," says Wilson, "We played harder, we were winning battles, and that's what it takes against a team that tries to play to that type of identity. So we were able to take it to them tonight and get the job done. It's nice to close out the season's series with a win against those guys."
