Connolly gave the Capitals a 1-0 lead with his fifth goal at 1:42 of the first period. Jakub Vrana's stretch pass sent Connolly alone on the right wing, and he skated around the net and pushed a backhand past Sergei Bobrovsky.
"The way the game is now the first goal doesn't mean as much as it used to, but it does a lot for momentum and makes you play looser, a little freer," Holtby said
Jaskin made it 2-0 at 10:19 with a deflection of a Boyd shot for his first goal for Washington. Jaskin was claimed off waivers from the St. Louis Blues on Oct. 2.
Ovechkin scored on a redirect from Michal Kempny with 19 seconds left in the first to make it 3-0.
Ovechkin has 10 goals and six assists during his streak, which is two shy of his NHL-best 13-game streak from Jan. 1-Feb. 1, 2007.
Boyd's first NHL goal in his 21st game increased the lead to 4-0 at 11:04 of the third period. Ovechkin had the primary assist.
"He feeds me a beautiful pass. I had a wide-open net for my first goal," Boyd said. "It was pretty cool. Obviously a night I'll always remember."
The fourth line of Jaskin, Boyd and Nic Dowd had two goals and two assists.
