Oshie gave the Capitals a 1-0 lead at 3:44 of the first period on a power-play goal with Marcus Johansson providing the set up with a backhand pass from the slot. His second goal came at 11:52 when he finished a 2-on-1 with a chip off a feed from Alex Ovechkin.
"I've been working pretty hard, but like you saw tonight, a lot of these are hats off to my linemates," Oshie said. "We've got a great team here. I've been fortunate enough to be at the end of the score sheet [on] a few things, but more importantly we've got our game back to where it needs to be."
Kucherov scored his 100th NHL goal at 15:52 during a power play to make it 2-1. The Lightning tied the game 2-2 on Killorn's first goal in 16 games at 16:08.

Williams scored his 20th goal at 3:14 of the third period to give Washington a 3-2 lead. He redirected a shot from Andre Burakovsky that got past Andrei Vasilevskiy. Carlson made it 4-2 at 5:30 with Oshie getting an assist.
"We started off good and came out with good speed to get a 2-0 lead," Backstrom said. "We got a little unlucky there at the end of the period, but stuff like that is going to happen. In the second and third we played even better."
Kucherov pulled the Lightning to 4-3 with 1:30 remaining but Oshie completed his hat trick into an empty net with 44 seconds left. It was Oshie's third NHL hat trick.
"They played well, give them credit, but we have to be better, a lot better, in those situations, more desperation in the game," Killorn said. "When we have an opportunity being 2-2 going in to the third period, we'll take that all day against a team like this, so we just have to be better in the third."

Unsung performance of the game
Burakovsky had an assist and was plus-1 with seven shots on goal in 15:12 of ice time after missing 15 games with a hand injury.
Highlight of the game
Ovechkin forced Vasilevskiy to commit to his side before passing to Oshie, who scored into the open net.
"I think when we move the puck and are sharp it makes everyone move a little bit quicker and the reads are easier," Oshie said. "For the most part we kept everything simple and got the job done."

They said it
"They played like a desperate team. We knew they were going to be a difficult team. They were tough on the forecheck, but we handled it well and got a big performance from Oshie and pulled out the win." -- Capitals goalie Braden Holtby
"They score that fourth one, but I think they battled hard, can't take away that we are playing a really good team and they make it hard for us. We battle back to within one again but we couldn't get the equalizer before they score the empty net. We just have to make sure this doesn't break us and we refocus for the next one." -- Lightning defenseman Victor Hedman
