Charlie Lindgren made 30 saves for the Capitals (10-5-2), who had won five straight games.
“Wasn’t good at all,” Washington coach Spencer Carbery said. “Right from the drop of the puck, not good.”
Edmonton was 3-for-4 on the power play; Washington was 0-for-5 and is 3-for-50 on the season (6.0 percent), going the past 10 games without a goal.
“We’re going to have to change a bunch,” Carbery said of his power play. “Tons of different things personnel-wise, puck-management wise, puck recovery, decisions, routes. You name it.”
Evander Kane gave the Oilers a 1-0 lead at 14:10 of the first period when he knocked in his own rebound during a scramble in front.
Nugent-Hopkins increased the lead to 2-0 at 15:24. McDavid’s centering pass deflected high into the air and Nugent-Hopkins waited for the puck to come down before batting it past Lindgren. The Capitals challenged the play for a high-stick, but the goal was confirmed.
Edmonton outshot Washington 21-6 in the first period.
“I think we didn’t play at all,” Capitals captain Alex Ovechkin said. “We give them lots of space. When they control the puck, it’s dangerous. In the first period especially, we make lots of turnovers, make mistakes and they get the lead, 2-0.”
The Oilers failed to protect a 2-0 lead in two of their previous three games.
“We've played a lot of really good 20-minute hockey games this year, but in this league, that's unfortunately not enough,” Draisaitl said. “I thought tonight all around was really good.”
Evan Bouchard increased the lead to 3-0 at 3:44 of the second period when his one-timer from the point deflected off Washington forward Nic Dowd’s stick and past Lindgren on a power play.
Draisaitl made it 4-0 at 4:48, taking a pass from McDavid and scoring from the slot on a power play.
