TAMPA -- The Washington Capitals scored four goals in the third period and defeated the Tampa Bay Lightning 5-2 at Amalie Arena on Saturday.
Lars Eller, Garnet Hathaway, T.J. Oshie and Tom Wilson scored in the period, and Ilya Samsonov made 26 saves for the Capitals (24-5-5), who have won eight of their past nine games.
"The second period we got into penalty trouble and spent quite a bit of time in the [defensive] zone," Capitals coach Todd Reirden said. "We regrouped, we talked about it between the second and the third. It was up to us to get back to our game for the third period where, if we do that, [we] come out with the outcome we wanted."

Brayden Point and Jan Rutta scored, and Andrei Vasilevskiy made 29 saves for the Lightning (16-12-3), who had won two in a row.
Tampa Bay forward Nikita Kucherov left the game at 10:29 of the second period after blocking a shot by Washington defenseman John Carlson that appeared to hit him in the right leg.
"You guys saw what happened," Lightning coach Jon Cooper said. "I don't have an update on him. Hopefully he's going to be OK. Obviously he's a huge part of our team."
Eller made it 2-1 at 1:58 of the third period, and Hathaway made it 3-1 45 seconds later at 2:43.

"It's a testament to the guys in this room how hard we came out in the third period," Hathaway said. "We didn't lose a step and we played our game."
Rutta made it 3-2 at 11:36.
"First goal of the season," Rutta said. "I had a couple of good looks and finally one went in."
Oshie scored on a wraparound to push the Capitals lead to 4-2 at 12:19.

Wilson scored into an empty net with 39 seconds remaining for the 5-2 final.
"Overall we probably took too many penalties," Washington center Nicklas Backstrom said after the Capitals went 4-for-5 on the penalty kill. "Tough second period there especially, other than that we worked ourselves into this game and had a good start to the third. That was huge. And we got two points."
Backstrom put the Capitals ahead 1-0 lead at 6:42 of the first period after Rutta lost the puck on a crisscross with him and Lightning forward Ondrej Palat, giving Backstrom the puck in front of the net.

"It was unfortunate, but you just have to turn the page," Rutta said. "It was pretty early in the game."
Point tied it 1-1 at 5:45 of the second with a power-play goal from the low slot.
"I thought we played well in the second period," Point said. "We had some good looks, [their] guy made some saves. Bottom line is in the third period we gave up some opportunities to a team you can't give opportunities to, and they capitalized."

They said it
"Tremendous game by Ilya tonight. We knew going into it for him, this was another way to evaluate where he's at in his game and his development coming up against a desperate team here that needs points or wants points. Obviously the firepower, it was a test. I thought he was really solid." -- Capitals coach Todd Reirden on goalie Ilya Samsonov
"[We] played 55 minutes of solid hockey, and every time we made a mistake it has ended up in our net. It's too bad. I want to sit here and say we deserved better, but at the end of the day we didn't because of a couple of mistakes we made." -- Lightning coach Jon Cooper
