Kuznetsov doubled that lead to 2-0 in the middle of the period, and Washington took that lead into the third. A Braden Holtby turnover turned into an instant Tomas Nosek goal, giving the Knights some life and cutting the Washington lead to 2-1 with 16 and a half minutes remaining.
The Caps closed ranks and kept the Golden Knights bottled up, and Washington's fourth line manufactured a brilliant forechecking goal to restore the two-goal cushion - Jay Beagle feeding Devante Smith-Pelly to make it a 3-1 game with just over six minutes remaining.
By night's end, the Knights had more shots blocked (26) by Caps skaters than they had put on Washington netminder Braden Holtby (22). Washington also outhit the Knights 38-31, and the Caps won 63 percent of the game's face-offs.
"It's the commitment to playing without the puck," says Caps center Lars Eller of the team's defensive concept. "Everybody - all five guys - knowing exactly what to do out there when we don't have possession, playing quick, turning the play around, playing to our strengths. We weren't perfect at that today, but we were good enough to win."
