The Red Wings went 0-for-3 on the power play but killed all four Capitals power plays, helped by several blocked shots; Jacob de la Rose and Nick Jensen each had to briefly leave the game on the same kill in the third period after blocking shots by Alex Ovechkin.
"It means the world to me to see guys playing like that," Howard said. "We're out there killing a penalty, and they are sacrificing their bodies to help us get a win."
Wilson gave the Capitals a 1-0 lead at 6:57 of the first when he scored off a pass from Evgeny Kuznetsov after the Red Wings failed to clear a rebound. The assist was Kuznetsov's 300th NHL point.
"You always have to be ready when you are out there with Evgeny," Wilson said. "You try to expect the unexpected, because his passes are so good. He's fun to play with when he's doing that."
Mantha tied it 1-1 at 14:08 when he stole the puck at the blue line and put a backhand between Holtby's pads for his 10th goal.
"I've got a long stick, and I've been trying to use it to my advantage on defense," Mantha said. "That's one time it worked."
Hronek gave the Red Wings a 2-1 lead at 6:48 of the second period from the edge of the crease after cross-ice passes by Gustav Nyquist and Dylan Larkin.
Boyd made it 2-2 at 6:19 of the third period on a wrist shot after a pass from Ovechkin.
"We had a 3-on-2 and I got the puck to [Ovechkin]," Boyd said. "He had an open shot, and we all know what kind of scorer he is, but he gave me a great feed and I was able to sneak it in."
