Raymond had two assists, and John Gibson made 26 saves for the Red Wings (34-19-6), who had lost four of five (1-3-1).
“It was good, I mean, you want to get back and start on the right note and thought we did that tonight and battled the whole game,” Gibson said. “They’re a good team, tough building to play in and big win.”
Brady Tkachuk scored, and Ullmark made 18 saves for the Senators (28-22-8), who are 5-1-1 in their past seven games.
“I definitely felt we deserved a better result,” Tkachuk said. “I thought we did a lot of great things tonight. Their goalie stood on his head, had a great game, and yeah, it’s just unfortunate we didn’t get the two points that we wanted.
It was the first game for each team following the break for the Olympics.
“After the first two shifts, we were processing the game slowly,” Detroit coach Todd McLellan said. “We were reacting slowly, not a lot of execution. I guess the part we liked is we stuck with it in the second and third and found a way to win, keep that team off the board.”
Michael Rasmussen appeared to give the Red Wings a 1-0 lead at 8:11 of the first period, but Ottawa challenged the play for offside, and the call was reversed after a review.
Tkachuk put the Senators up 1-0 at 18:44 with a wrist shot from the high slot while on the power play. Jake Sanderson's shot from the point deflected off Rasmussen to Tkachuk, who beat Gibson through traffic. Tim Stutzle's secondary assist on the goal extended his point streak to eight games (six goals, five assists).
“I thought our start was phenomenal,” Ottawa coach Travis Green said. “We got right to our game, and Detroit's a good team, they’re going to push back. They raised their game after the first period.”
Larkin tied it 1-1 with a power-play goal at 5:24 of the second period, finishing Raymond's backhand pass from the goal line with a snap shot from low in the left circle to the glove side on Ullmark.
“The power play, I think it woke us up a little bit,” Larkin said. "Just hounding pucks and we slowly started to tip the ice.”
