Filip Forsberg scored for the Predators (13-22-7), who have lost consecutive games. Juuse Saros made 12 saves.
“Right now nothing is really going our way,” Nashville coach Andrew Brunette said. “There’s nothing we can do except wake up and go back to work. I always believe, and I guess I’m starting to question myself, I think if you get chances, sooner or later they’re going to go in.”
Frank gave Washington a 2-1 lead at 8:30 of the third on a stretch pass from Matt Roy.
“It’s pretty special with a guy that’s just earned everything,” Wilson said. “Hockey is such a great game at every level, but a guy that just stuck with it. Heck of a player, great guy, and he comes up and his work really paid off. And you see him have success last night in front of his family and then tonight his first goal, it brings you back. It’s what is so great about the game when a guy can score his first goal. It’s a dream come true.”
Mangiapane extended it to 3-1 at 14:54 on a backhand shot from the slot off a pass from Brandon Duhaime.
Wilson gave the Capitals a 1-0 lead at 9:03 of the second period with a power-play goal. He fanned on his first attempt on a pass from Dylan Strome, but his second shot attempt beat Saros five-hole.
“I feel like our power play is one of those where it doesn’t matter how it looks, as long as it’s productive,” Carbery said. “And that’s exactly what our power play is doing right now. Sometimes it doesn’t look great. Sometimes we’re giving up a breakaway here and there, and we’d like to clean that stuff up and the entries aren’t on point at times. But when you’re scoring one a night, that’s delivering the goods.”
