Alex Ovechkin scored twice to give him 48 on the season, John Carlson also scored and Braden Holtby finished with 29 saves for Washington. The Capitals remained two points ahead of the New York Islanders atop the Metropolitan Division.

Killorn, who entered the game with 13 goals on the season, capped off the hat trick with an empty-netter with 47 seconds left. Gourde capped the scoring with another empty-netter 45 seconds later.

The Lightning jumped on the Capitals quickly as Brayden Point set up Johnson on a 2-on-1 at 8:35 of the first. Killorn made it 2-0as he sent the puck from the boards toward the front of the net where it bounced off Washington defenseman Dmitry Orlov and past Holtby at 10:33.

Carlson cut the deficit in half as a blocked shot bounced out to the right point where he stepped into a one-timer for his 12th at 12:06.

Killorn answered that as he forced his way up the ice and outmuscled Michal Kempny for an initial shot before putting his own rebound with 4:04 left in the period to make it 3-1.

After the Lightning failed to convert on 1:28 of 5-on-3 power play time, 42 seconds of which carried over into the second period, the Capitals struck on the power play after Carlson's shot deflected off T.J. Oshie in the high slot and landed right in the path of Ovechkin for a quick wrist shot to make it 3-2 at 7:33.

Cernak regained Tampa Bay's two-goal lead with his fourth of the season, coming open down the right circle before snapping a shot through Holtby's legs at 2:45 of the third. Ovechik scored his second of the night off a carom from Orlov's shot off the end boards to cut the Lightning lead to 4-3 at 12:56.
