WASHINGTON -- Alex Ovechkin scored 22 seconds into overtime to give the Washington Capitals a 6-5 victory against the Toronto Maple Leafs at Verizon Center on Tuesday.
It was Ovechkin's 19th NHL overtime goal, tying Jaromir Jagr for most in League history.
"Obviously, it's a fun game to watch," Ovechkin said. "It's nice we didn't give them momentum in the third, score big goal right away. We knew the game was out there and we just have to continue to push, and we got the result."
Justin Williams, T.J. Oshie, Evgeny Kuznetsov, Dmitry Orlov and John Carlson scored for Washington (23-9-5). Kuznetsov had three assists, and Williams and Marcus Johansson each had two.

The Capitals trailed 4-2 entering the third but tied the game 4-4 on goals 1:19 apart from Kuznetsov and Orlov. Kuznetsov scored at 2:20 to make it 4-3, and Orlov's second goal of the season at 3:39 tied it.
Williams scored a power-play goal at 1:14 of the first period to put Washington ahead 1-0. His 10th goal came off a deflection of an Orlov point shot.
Kadri tied it 1-1 with a power-play goal at 6:39 of the first. He put in a loose puck in the crease for his 14th goal.
Brown made it 2-1 when he beat Holtby top shelf at 11:44 of the first for his eighth goal.
Oshie scored off a pass from Williams with four minutes left in the first to tie it 2-2, but Gauthier tipped a loose puck behind Holtby to give the Maple Leafs a 3-2 lead with 1:54 left in the period.

Komarov scored on the power play to make it 4-2 at 13:33 of the second period off a slick pass from Auston Matthews, who had two assists to extend his point streak to seven games.
"We've had a good run here on the road," Maple Leafs coach Mike Babcock said. "I think that's six games in a row we got points in, and five of them we won. You can't often get points on the road if you don't play right, you don't play well. Tonight, I thought the power play was good enough, but we weren't good enough."

Ovechkin got open at the bottom of the left faceoff circle and beat Andersen with a one-timer to the short side off a pass from Carlson.

They said it
"It was one of those games where every time they did get a chance, it seemed to end up in the back of our net. ... A little bit of resiliency for us. We'll take a good comeback. I thought when it counted, everybody stepped up." -- Capitals coach Barry Trotz
"It was fun. We felt like we needed a little excitement in here. I think we just kind of willed our way to that win. It was fun and exciting for everybody." -- Capitals forward Justin Williams

"I'm just trying to get the goalie to move to one side and put it back on the other. [Leo Komarov] was in really good position. I was just lucky to get it to him there, and stick on the ice, he put it in. It was a nice play by him." -- Maple Leafs rookie forward Auston Matthews
