Boston went on the game's first power play just 23 seconds later but wasn't able to convert. On its own first power play of the game, the Caps grabbed a 1-0 lead at 7:33 when Oshie slipped a shot through Dan Vladar from the diamond, his team-leading ninth power-play goal of the season.
Sixteen seconds later, the Caps doubled their advantage on a slick goal from Eller. Garnet Hathaway chipped the puck from the Washington zone into Boston territory and went for a change. Carl Hagelin won the race to the puck, curling off at the right half-wall and feeding Eller, who skirted Boston forward Anton Blidh - fighting off a hook as he did - and roofed a shot behind Vladar for a 2-0 Washington lead.
With their third goal in a span of just 129 seconds, the Caps opened up a 3-0 lead on a 3-on-2 rush. Dmitry Orlov led the charge from the middle of the ice, sending Daniel Sprong into Boston ice with speed down the right side. Sprong went back to Orlov, who sent a sublime backhand feed to Sheary on the left wing. From the inside of the left circle, Sheary finished the tic-tac-toe play at 9:42 to make it 3-0 for Washington.
In the second period, the Caps hung three more lamplighters on the Bruins, including two more power-play goals.
With time winding down on a Washington power play early in the middle period, the Caps were whistled for icing. They had three wingers on the ice at the time, so Sheary took and won the ensuing defensive zone draw and scored 13 seconds later, finishing off a nice feed from Tom Wilson to make it 4-0 at 4:41.
Late in the period, Nic Dowd lost a draw in his own end and extended the Washington lead to 5-0 just nine seconds later. Although Boston "won" the draw, Hagelin was first to the puck and he scooted through neutral ice with it, leaving it for Dowd just above the Boston line. Dowd carried in and fired from the outside of the left circle, beating Vladar high to the far (glove) side at 16:03.
As another Caps power play ticked into its final seconds late in the middle frame, Alex Ovechkin put a perfect feed on Wilson's tape for a back-door lay-up at 18:24, making it a 6-0 game.
Boston scored its lone goal of the game on a power play three minutes into the third period. Craig Smith scored on a rebound to make it 6-1.
Seconds after a Charlie Coyle slashing minor expired in the middle of the third period, Oshie netted his second goal of the game, batting a Nicklas Backstrom pass out of midair and into the net at 10:13 of the third.
Eller closed out the scoring at 13:14 of the third, scoring on a double deflection. The shot originated from Dillon at center point, and Oshie also got a piece of it en route to the net.
