"We both were talking a bit before the game about it," said Bowey, who played his 78th NHL game. "We've been together for a long time down in Hershey (in the American Hockey League), and whenever you see any of us guys have success from down there] it's very special and I'm very happy for him."
Lewington, who was playing his second NHL game, said, "At the morning skate, I said to [Bowey], 'I think you've got one tonight.' And then actually [Brett Connolly] said before the game, 'Shoot the puck, I think something good will happen.'"

Tom Wilson had a goal and an assist for the Capitals (24-10-3), who have won four in a row and nine of 10.
Colin White and Mark Stone each had a goal and an assist for the Senators (15-20-4), who have lost four in a row and nine of 12. Marcus Hogberg made 21 saves in his NHL debut.
"It's a good opportunity for me to show who I am," the 24-year-old goalie said. "It's a good test for me. ... It's nice to have it done. I think the boys played really good in front of me, helped me see some pucks."
Pheonix Copley made 31 saves for Washington. He is 8-2-1 this season backing up Braden Holtby.
"We're extremely lucky to have two [goalies] in this room that give us a chance to win," Wilson said. "Even in moments when we're not playing great throughout the night, [Ottawa] had some waves, they played hard.
"To have a goalie back there every night that's going to give you an opportunity to win, again, great guy, great teammate. We're pretty lucky to have both [Copley] and [Holtby], a pretty good team holding the fort down for us back there."
Lewington's wrist shot from the slot went into the left corner to make it 2-0 at 16:00 of the first period. Bowey scored on a slap shot from the top of the slot 1:01 into the second period to make it 3-0.
