The Caps took some immediate momentum from that successful power play foray, but before the end of the frame, the Canucks were again buzzing the Washington zone. Vancouver put seven shots on Samsonov in less than four minutes to close out the first, a span in which Aliaksei Protas swept a loose puck out of the Caps' crease to prevent a goal, and in which Nic Dowd was sent away for interference with nine seconds left in the first, giving the Canucks a carryover power play.
While still on that power play in the first minute of the second, the Canucks evened the score on Elias Pettersson's shot from the right circle. Just over four minutes later, Pettersson scored again. This time, he scored from below the goal line, banking a backhander off Samsonov and in to give Vancouver a 2-1 lead at 4:48 of the middle stanza.
Demko made two good saves on Daniel Sprong, one late in the first and another early in the second. He also denied Ovechkin twice on the same shift midway through the second, halting him on a 2-on-1 rush from the left side and a 3-on-1 burst from the right side.
Late in the second, the Caps went shorthanded for a second time when Garnet Hathaway was sent off for roughing. Less than a minute later, the Canucks extended their lead to 3-1 when Bo Horvat snapped a shot past Samsonov at 18:50 of the second.
Washington was nearly flawless in the second period on Saturday, but it yielded three or more in the middle frame for the third time in five games in Sunday's loss.
Early in the third, Tom Wilson drew an interference call on Vancouver's Tanner Pearson, and then Wilson scored his second goal in as many days on the ensuing power play. Taking a tee-up feed from Evgeny Kuznetsov, Wilson snapped a shot past Demko from his post in the slot on the power play, pulling the Caps within a goal at 6:22 of the final frame.
