Bobby Ryan scored twice, including the game-winner at 2:33 overtime, to help the Senators rally from a two-goal deficit to earn a 3-2 victory over the St. Louis Blues on Monday night.
Assisted by Mark Stone and Chris Wideman, Ryan fell down in the offensive zone, got up, got the puck back, had a give-and-go exchange with Stone and then faked out Elliott for the goal.
Mike Hoffman scored his 19th of the season and Andrew Hammond made 36 saves for the Senators, who had lost three straight and been shut out in back-to-back games against Chicago and New Jersey.
Troy Brouwer and Kevin Shattenkirk scored for St. Louis, while Brian Elliott made 29 saves. The Blues have lost three straight and four of five and now head West for a three-game road trip against Colorado, Anaheim and Los Angeles.
The Blues scored first, with 5:44 left in the first period, when Brouwer got past defenseman Patrick Wiercioch and beat Hammond glove side for his seventh goal of the season and first in 10 games.
Shattenkirk made it 2-0 with a power-play goal at 7:42 into the second period, aided by a screen from David Backes in front.
The Senators got a power-play goal from Hoffman, his 19th, with 1:14 remaining in the period. The goal came on a slap shot from the left circle that Elliott got a piece of but couldn't stop.
Ryan tied it 5:01 into the third period with a power-play goal just 4 seconds after St. Louis' Jay Bouwmeester was called for tripping. It was Ryan's 200th career goal.
