The Caps killed off a Boston power play without incident, but the Bruins pulled even with a fourth line goal in the immediate aftermath of an offensive-zone draw win. Curtis Lazar won the draw, and Jake Debrusk collected it, fired and scored in a span of three seconds, tying the game at 13:10 of the first. Vanecek injured himself doing the splits in an attempt to make the stop, and he left the game at that point in favor of Anderson, who logged roughly five percent of Washington's total goaltending minutes in the regular season.
Soon after Anderson's entry into the crease, the Caps killed off a second Boston power play.
Just ahead of the midpoint of the second, the Caps regained the lead when they made the Bruins pay for an unforced error, an icing.
Although Boston was credited for winning the ensuing draw in its own end of the ice, it was Washington that gained possession after the puck drop. Anthony Mantha gained control and rolled it out to Brenden Dillon at the left point. Dillon put a shot toward the net, and it clicked off the stick of Bruins defender Jeremy Lauzon and went past Rask at 8:44, giving the Caps a 2-1 lead.
Seventeen seconds later, the Caps had their first - and as it turned out only - power play of the game when Lauzon issued several cross-checks to Ovechkin's upper body in the corner of the Boston zone. Washington got a couple of shots on net, but it was unable to expand its lead.
Boston answered back and knotted the game at 2-2 late in the middle period, pulling even on the third of its four power plays in the game. From the top of the paint, Boston winger Nick Ritchie scored on the rebound of a Pastrnak shot from the point, tying the game at 16:38 of the second.
The third period was scoreless and more free flowing. While the first 40 minutes featured a total of 50 face-offs, there were only 11 draws in the final period. The entire first 60 minutes were fairly even and tight in terms of time, space and scoring chances.
Early in the overtime session, the Caps put an end to the evening. Dowd was on with Oshie and Wilson, put out initially to take a defensive-zone draw some 36 seconds before he scored the game-winner.
After Dillon laid out to block a Kevan Miller shot, Dowd broke the puck out of Washington territory and sent Wilson into Boston ice along the right-wing wall. After gaining the zone, Wilson went laterally to Oshie at center point as Dowd drove the net. Oshie cranked a one-timer and Dowd deflected it; it trickled through Rask's pads and wobbled over the goal line at 4:21, making a winner of Washington and Anderson.
"I didn't see anything," says Oshie when asked about the game-winner. "All I know is Tom made a good play to throw it up to me. I don't know who was in front of me; I think it was [David] Krejci maybe. Someone was right in front of me, and I just tried to hit the puck as hard as I absolutely could, and miss him. And then all of a sudden, I didn't even see it go in, I just saw people skating toward me.
