Less than three minutes later, the Caps again turned the puck over at their line, and again the Habs made them pay. This time it was old friend Joel Ward who collected the puck and fed Michael Chaput, who put it behind Copley to make it a 2-0 game at 5:51.
Washington permitted a goal in the final minute of each of the three periods of its previous game, a 5-2 loss to the Boston Bruins on Tuesday, and the Caps kept that dubious streak intact in the final minute of the first frame. Yet another turnover - this one deeper in the zone - resulted in a Jacob de la Rose goal at 19:23, pushing the Habs' lead to 3-0.
The Caps had as many shots as the Canadiens had goals in the first, coming out on the short end of a 14-3 disparity in that department.
Early in the second, the Canadiens pushed their advantage to 4-0 on a power-play goal. Seconds after Andre Burakovsky had a shorthanded semi-breakaway, the Habs struck in transition, Gallagher feeding Jacob de la Rose perfectly and de la Rose tucking the puck neatly into the net at 2:28.
The Caps cut into the Canadiens' lead with a pair of power-play goals in the middle frame. First, Alex Ovechkin drilled a shot to the net from his left dot office at 5:17. From center point Christian Djoos put the puck on a tee for the Caps' captain, and Ovechkin did the rest, making it a 4-1 game.
