Philadelphia's Matt Read started the shootout with a goal, but Milan Michalek responded with a goal of his own. After Claude Giroux's backhander sailed high, Spezza beat Bobrovsky with a snap shot. Anderson then stopped Danny Briere to seal the victory for Ottawa.
The Senators put three goals on the board in the first period. At the 6:04 mark, Alfredsson gathered the puck behind the net and pretended like he was going for a wrap-around. Instead, Alfredsson backhanded a pass to the side of the net for Spezza and Ottawa took a quick 1-0 lead.
A turnover by the Flyers led to the Senators' next goal. Eric Wellwood tried to clear the zone, but the disc hit off the boards and went to Erik Karlsson. His pass to the high slot set up an Alfredsson one-timer that sailed past Bobrovsky at the 11:39 mark.
Neil made it a 3-0 game with 5:33 to go. He controlled the puck along the left boards and fired a shot through a maze of players. The disc snuck through Bobrovsky and past the line.
Philadelphia came storming back in the middle stanza. At the 2:59 mark, Brayden Schenn made a nice move before firing a shot on net from the high slot. The puck hit off Simmonds' nose and went into the net.
With 5:22 to go, Couturier went charging toward the net. Anderson got a piece of his backhander that managed to trickle past the line. An Ottawa player ran into the net as the puck went in. Following a review, it was determined the disc passed the line prior to the net coming out of place.
The Flyers made it a 3-3 game with 2:43 left. Briere fed a pass from the bottom of the right circle to Coburn in front. Coburn was able to chip the puck past Anderson.
Bobrovsky made five saves in the third frame, while Anderson stopped four shots.
Briere almost ended the game in overtime, but his shot from the slot hit off the post. Philadelphia also failed to score on the power play in the final 49 seconds of the extra session.
