The win gave the Flyers a .500 record for the first time this season, at 11-11-1. Philadelphia has won five of its last seven games.
Marc Methot scored for the Senators, who lost in regulation for the first time since Feb. 16.
Goalie Ben Bishop had won his last four starts for Ottawa, posting 1.69 goals-against average during the stretch. But the Senators have had trouble scoring on the road and struggled to get quality chances against the Flyers.
When we started our journey we made a commitment to our fans to be relevant and to see the Chicago Blackhawks become the best professional hockey organization. There are not two finer symbols of that than Jonathan Toews and Patrick Kane. The commitment we have made to these incredible young men is equal to the commitment they have made to our team, our fans, our entire organization and the city of Chicago.
