"[Duclair] had a really good night out there," Senators coach D.J. Smith said. "He's obviously got speed, which makes him a dangerous player, and he was really taking advantage of it."
Duclair acknowledged they had extra incentive to win for Smith, who was coaching for the first time against the Red Wings, the team he cheered for while growing up across the river in Windsor, Ontario.

"It's always big when someone is playing at home for the first time, so we knew it would be huge for Coach," Duclair said. "The boys wanted to make sure he got two points in front of his family."
Jean-Gabriel Pageau and Brady Tkachuk scored, and Anders Nilsson made 35 saves for the Senators (9-11-1), who won for the fifth time in seven games.

"We've been working hard to get some wins on the road, but we haven't had much success," Pageau said about the 3-7-1 road record. "We're really happy to come into Detroit and get two points. That's big."
Valtteri Filppula had a goal and an assist, and Jonathan Bernier made 29 saves for Detroit (7-13-3), which had its five-game point streak end (3-0-2).
The Red Wings led 2-1 after the first period but allowed three goals in the second.
"We didn't capitalize on our chances and we didn't manage the puck through the neutral zone," Red Wings forward Dylan Larkin said. "They've got some guys who can really skate and we didn't do anything to stop them."

Duclair tied it at 2-2 at 5:00 of the second, scoring inside the left post.
Pageau made it 3-2 at 5:57, scoring his ninth goal of November on a 4-on-4 breakaway.

"We were okay in the first period, but we were terrible in the second period," Red Wings coach Jeff Blashill said. We started the second period with a power play and a chance to make it 3-1. Instead, we gave away the momentum."
The Red Wings had a 2-on-0 shorthanded breakaway at 16:55, but Nilsson stopped Frans Nielsen's shot. Nielsen doesn't have a point in 19 games this season.
"I was just glad I could get my pad down and he didn't lift the puck," Nilsson said. "Making a save like that is huge for my confidence, but it is even more important to go into the third period with that two-goal lead."
Detroit outshot Ottawa 16-3 in the third period but didn't score until Anthony Mantha cut it to 4-3 at 17:14 with Bernier on the bench for an extra skater.
"If we played three periods like that I'd like our chances, but we need to get a much better net-front presence," Blashill said.
Duclair gave the Senators a 1-0 lead at 3:08 of the first period, knocking down Thomas Chabot's pass with his glove and breaking in to score his eighth goal of the season.

"That goal should never, ever happen in the system we play," Blashill said. "That's inexcusable."
Filip Hronek appeared to tie the game at 3:42, but Ottawa successfully challenged for an offside call on Tyler Bertuzzi.
Robby Fabbri tied it 1-1 at 9:57 when Senators forward Logan Brown deflected the puck into his own net while trying to clear the rebound of Fabbri's shot.
Filppula's shorthanded goal at 18:32 gave the Red Wings a 2-1 lead.
They said it
"I know Detroit is good off the rush, but I felt like we managed them pretty well, so I still felt comfortable that we were going to win. Even when they got that late goal, I was comfortable that we were going to ride out the storm and come out with two points." -- Senators goalie Anders Nilsson on Detroit's 16-shot third period
"We have to get our legs going. We came out and got a couple big goals in the first, but we came out slow in the second period. In this league, teams aren't going to sit back for 60 minutes. We've talked about it a lot. We have to find a way to bottle them up when the momentum goes against us and find a way to get it back." -- Red Wings forward Dylan Larkin on Ottawa's three-goal second period
