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.
You don't see many. The [Drew] Doughtys, the [P.K.] Subbans, those are guys that create offense from the back and then on top of that ability, the size that he has. In the West you play against some pretty big players, and being able to clear the crease and contain the [Ryan] Getzlafs and the [Corey] Perrys and [Anze] Kopitars and players like that, we're excited about him going back there.
