WATCH: All Senators vs. Flyers highlights
Jordan Weal scored for the Flyers in the shootout when he beat Craig Anderson with a wrist shot in the first round.
"I had a plan in mind," Weal said. "Maybe it didn't go exactly as planned but it found the back of the net and we got a big win."
Kyle Turris and Bobby Ryan missed for the Senators in the shootout, and Tom Pyatt was stopped by Steve Mason.
Weal and Brayden Schenn scored, and Mason made 26 saves for Philadelphia.
Turris had a goal and an assist, Erik Karlsson scored, and Anderson made 33 saves for Ottawa.
Weal's goal at 14:01 of the third period tied the game 2-2 after Anderson turned over the puck.
"We limited his options and we took the walls away [so] he couldn't make a play," Weal said. "I tried to read off where his stickblade was angled and he tried to make a play up the middle. Was able to capitalize and intercept it and put it in the back of the net."

Anderson took the blame for the Senators getting one point.
"It should have never gotten to the shootout, that's the bottom line 100 percent," he said. "Horrible read by me and our guys deserved better than that."

They said it
"We're not going to look at this and say, 'Oh our goalie made this gigantic mistake.' It happens. For all the saves he's made this year and for all the times he's made us win a game he gave us a point tonight too. … We are all behind him and we are going to keep getting behind him. He's played terrific for us and he's going to keep playing great." -- Senators coach Guy Boucher on Craig Anderson
"You can't [scoreboard watch]. There's too many teams that we're trying to catch and push ahead of. We worry about our games and hopefully we get some help, but that's out of our control. We got the two points again tonight and we're going to worry about Thursday's game and go from there." -- Flyers defenseman Michael Del Zotto
