Kyle Turris had the shootout winner and Dion Phaneuf scored his first goal in an Ottawa uniform as the Senators defeated the Detroit Red Wings 3-2 on Saturday.
Zack Smith also scored for the Senators (28-26-6), who have won three straight games for the first time since Nov. 19-24. Craig Anderson turned away 29-of-31 shots.
Andreas Athanasiou and Brad Richards scored for the Red Wings (29-21-9) as Petr Mrazek made 25 saves.
The Senators have struggled when giving up the first goal this season (11-23-6), but were able to change its fortune on this night thanks to its newest player.
Trailing 2-1 with just under four minutes remaining in regulation Phaneuf ripped a shot through traffic and beat Mrazek far side to force overtime.
Anderson got the 18,930 on hand at Canadian Tire Centre in the game with a double-stack pad save on Justin Abdelkader early in the first period.
The Red Wings then opened the scoring at 10:46 of the second as Erik Karlsson made a brutal giveaway, putting the puck right on the stick of Athanasiou, who quickly beat Anderson.
Ottawa tied the game exactly one minute later when Jean-Gabriel Pageau found Smith skating through the slot and he redirected the puck through Mrazek's legs. Smith tied a career high for goals with his 14th of the season.
Detroit regained the lead late in the second on an unlucky play for Karlsson, who attempted to bat the puck out of the air but sent it right past Anderson instead. Richards was given credit for the goal.
The Red Wings had a scare early in the game as Mrazek appeared shaken after taking a Patrick Wiercioch shot early in the period, but he remained in the game.
The Senators now head out for a three-game western road trip, while Detroit will wrap up its four-game road trip Sunday against the New York Rangers.
Notes: Senators C Shane Prince and D Chris Wideman were healthy scratches for the Senators. Detroit's leading scorer C Dylan Larkin was unable to play due to illness and D Jonathan Ericsson missed his fourth straight game due to a lower-body injury. D Jakub Kindl was a healthy scratch.
