Feeding off the energy of the crowd of 29,516 and the emotion of the pregame festivities involving the U.S. Naval Academy's midshipmen, the Capitals jumped on the Maple Leafs, who were 13-2-2 in their previous 17 games, from the drop of the puck. After drawing an early power play, they converted with a goal from Evgeny Kuznetsov to take a 1-0 lead 3:50 into the game.
When Toronto's Zach Hyman scored at 5:20 to make it 1-1, Alex Ovechkin answered 59 seconds later with his League-leading 40th goal to put the Capitals ahead 2-1. Another power-play goal from Nicklas Backstrom made it 3-1 with 3:40 remaining in the first period.
"It was a big game, big stage, obviously, against a very good team that's probably the hottest team since probably the all-star break," Capitals coach Barry Trotz said. "And I thought we did the right things. We were skating. We were putting pressure on the puck. We had people in the right areas and we were committed in the right area.
"So it was a good performance, because we had a couple that we probably could say wouldn't be our best."
There were plenty of positives for the Capitals. Each time the Maple Leafs scored, the Capitals responded less than a minute later. Defenseman John Carlson's rebound goal at 8:05 of the second period that made it 4-2 came 43 seconds after Nazem Kadri pulled the Maple Leafs within 3-2.
Kuznetsov, Backstrom and Carlson each had three points (one goal and two assists each) to tie the record for the most points in an NHL outdoor game. Ovechkin scored his sixth goal in his past seven games to move within two of becoming the 20th player in League history to score 600 in his career.
Rookie forward Jakub Vrana scored on a breakaway 10:49 into the second period to end a 25-game goal drought that dated to Dec. 14. And Holtby made 27 saves to end his personal six-game losing streak (0-4-2).
