TORONTO -- The Ottawa Senators dealt their provincial rivals a demoralizing loss.
"You walk away feeling completely discouraged when you should walk away quite hopeful," Toronto coach Paul Maurice said. "It was a hard-fought game and to have it go like that, it hurts."
Devereaux -- recalled from the minors on Thursday because of a slew of injuries -- gave Toronto a 2-1 lead with 6:20 left in the third with a wrist shot to Emery's blocker side.
Kelly tied it with a one-timer from in front after Wade Redden made a nice pass from the boards.
"We should have won. We had a 2-1 lead in our building and we didn't win," Raycroft said. "It's frustrating."
Kelly called it a good character win.
"We battled back," Kelly said. "Philly had the big goal in overtime but Ray was the man tonight."
Emery had shutouts in his previous two games and was outstanding against last-place Toronto, who now trails third-place Ottawa by three points in the Northeast Division.
"We're in the same division. These games are worth four points," Emery said. "There's no love lost between the teams. We gun for each other."
Emery's scoreless streak ended at 160:04 when Steen scored on a rebound at 18:54 of the first.
After Kelly skated in on a breakaway and put a shot on Raycroft, McAmmond poked in the rebound for a short-handed goal at 5:37 of the second.
The Maple Leafs skated in on a 3-on-2 less than a minute later, but Emery made a sprawling save on Tomas Kaberle.
"We threw a lot of rubber at Emery. That's all you can do when have a hot goalie like that," Devereaux said.
