On defense, Seattle stuck with its system against the NHL team with the third best record in the league, playing physical and sound.
Kraken players got into shooting lanes and blocked 12 shots, which is all about a willingness to put your body in danger's way. When a shot did get through to Philipp Grubauer, the Kraken tightened in front of the net and were the first to rebounds.
With three-and-a-half minutes left in the game, Grubauer was on his back, diving to make a last-second stick save. The puck stayed in the crease, but three Kraken players were there to support their goalie and clear the puck to safety.
It was one of several scramble plays in front of the net. The Kraken won them all.
"Not only blocking shots but letting me see the puck," Grubauer said about his teammates after Sunday's win. "If there's a rebound, our guys are right there."
"That's how teams create offense and it's a huge part of the game. That's where we need to be good, in front of our net and in front of their net."
Killing penalties takes work, courage and a great deal of grind. The Kraken were perfect on the penalty kill Sunday, wiping out all four of the Capitals' chances. Washington has one of the league's top power-play units led by Alex Ovechkin, who is highly dangerous with the man advantage.
Seattle kept the Caps to the outside for the most part on the power play. Ovechkin was able to fire off a few of his patented shots from the faceoff dot but the Kraken had cleared a path for Grubauer to see them and stop them.
