Caggiula tied it 1-1 at 8:25 of the second period, shooting into an open net after receiving a no-look backhand pass from Nylander.
"I think we dictated most of the play tonight and we weren't rewarded for it, but that's the way hockey works sometimes," Caggiula said. "You don't always get the bounces, you don't always get the results you're looking for, even if you play the prototypical game or the perfect game. We didn't get rewarded tonight, but this is something we can build off of heading into the next one."
Dowd gave Washington a 2-1 lead with a shorthanded goal on a 2-on-1 at 9:53 of the second.
"It was a good turning point there," Dowd said. "Obviously, unlucky on the [double-minor penalty], but you try and take momentum away any time you can, you know? Our power play got us going early with momentum. Special teams was a big factor tonight."
Ovechkin scored on a one-timer from the left circle to extend the lead to 3-1 at 3:52 of the third period. With the primary assist on the play, Carlson extended his point streak to seven games (three goals, 12 assists).
Kubalik cut it to 3-2 on a rebound in front at 6:05 of the third, and Kane tied it 3-3 at 9:58 on a 2-on-1 following a giveaway by Eller.
