After killing off an early New York power play without, the Caps grabbed a 1-0 lead mere seconds after the final television timeout of the first period.
Coming out of the timeout, Nic Dowd won a face-off in Washington ice. Garnet Hathaway quickly broke the puck out of the Caps' end, feeding Carl Hagelin in neutral ice. Hagelin bumped it to Dowd, who gained the line and fired a shot past New York's Igor Shesterkin, just eight seconds after the draw in the Washington end.
Dowd's goal marked the first time Washington has led in three games here in New York this season. Less than two minutes later, the Caps doubled their advantage.
Coming into New York ice down the left-wing wall, Conor Sheary rolled the puck around the wall and went to the back door on the left side. Tom Wilson collected it on the right half-wall and went to the middle for Michael Raffl, who kicked it with his skate blade straight to Sheary. From just off the left post on the weak side, Sheary spun and slipped a shot through on the short side, making it 2-0 at 15:44.
New York's eminently dangerous top trio got one of those goals back with exactly two minutes left in the first. Mika Zibanejad scored off the rush, firing a shot to the top far corner of the cage from the left circle to make it 2-1 aft the first intermission.
Early in the second, the Caps ran into some penalty woes. New York tied it up on the power play early in the middle frame, Zibanejad netting his second of the night at 2:30 when he finished off a tic-tac-toe sequence on a New York power play.
Just over two minutes later, the Rangers took the lead when Kaapo Kakko converted an Alexis Lafreniere feed on a 2-on-1 rush, putting New York up 3-2 at 4:35 of the second.
Caps coach Peter Laviolette called his timeout at that juncture.
Less than two minutes later, Washington was deemed guilty of having too many dudes on the ice, giving the Rangers another opportunity with the extra man. Late in that power play, a multi-player scrum broke out after the whistle, resulting in multiple penalties, and a 5-on-3 for the Rangers for 27 seconds. Wilson was tagged with a double-minor and a 10-minute misconduct, taking him out of commission for the rest of the period, and leaving Washington with nine forwards for the remainder of the second and into the early minutes of the third.
The Caps navigated their way through that patch of peril, and they finally managed to get the game tied up late in the period.
Dowd got in on the forecheck and picked the pocket of Rangers defenseman K'Andre Miller, who was at the end of a 90-second shift. Dowd and his linemates swarmed the front of the Rangers net and started whacking away. From the slot, Hathaway scored to knot the game at 3-3 at 18:30 of the frame.
