Just over two minutes later, the Caps doubled their advantage on the game's first power play. From the right wing corner, Evgeny Kuznetsov fired a hot feed to Carlson at center point. Carlson one-timed it right back at the net and in for a 2-0 Caps' lead at 7:38 of the first.
The Lightning responded 63 seconds later, making 2-1 on a Nikita Kucherov goal from the slot at 8:41. Washington wasn't able to exit its zone cleanly, and Caps goalie Ilya Samsonov was sans stick on the play.
Tampa Bay appeared to have pulled even just over two minutes later when Ondrej Palat scored from the slot on a follow-up, but officials immediately ruled that Kucherov had played the puck with his hand, nullifying the goal and preserving the Washington lead.
With just under five minutes remaining in the first, the Caps restored their two-goal cushion and their captain claimed another milestone in the process. After the Caps were guilty of icing, Evgeny Kuznetsov won the defensive zone draw and Washington broke it out, with Carlson carrying into Tampa Bay ice on an odd-man rush. He dished to Alex Ovechkin, whose feed for Kuznetsov got tangled in the center man's skates. No problem, Ovechkin simply retrieved it and fired it home, bar down, for a 3-1 lead at 15:10. The goal was Ovechkin's 43rd of the season, and the point was the 1,400th of his career.
Again, the Bolts responded quickly. After a quick neutral zone regroup, the Lightning regained Washington ice and made it 3-2 when Nick Paul fired a shot past Samsonov from the high slot at 16:31.
Carlson appeared to have restored Washington's two-goal cushion yet again when he scored with 5.7 seconds left in the first, but Tampa Bay issued a successful coach's challenge, alleging the play was offside. Video review showed that Carlson himself was just a shade early entering the zone, and the Caps had to be content with a one-goal lead after 20 minutes of play.
Things simmered down some in the second as far as lamp lighting was concerned. The two sides traded unsuccessful power plays, and then Washington got another crack with the extra man late in the period, and it was able to restore its two-goal cushion once again.
Carlson teed up Ovechkin for a one-timer from the office, but Bolts blueliner Jan Ruutta blocked it. Puck hound T.J. Oshie retrieved the disc, and he sent it back to Carlson. This time, Carlson crept into the high slot and beat Vasilevskiy with a wrist shot, making it 4-2 at 16:35 of the second.
