Pittsburgh trailed 5-3 after 40 minutes, but cut the deficit to 5-4 when Sidney Crosby scored his third goal of the year 11:43 into the third period. However, from there, the Senators re-assumed control of the game as Jason Spezza made the score 6-4 with his 31st of the season at the 13:16 mark. Daniel Alfredsson, Ottawa's only multiple-goal scorer on the evening, made it 7-4 at the 17:05 mark before Colin Greening finished the scoring with 1:52 left.
With the loss, the Penguins fell three points behind the New York Rangers in the race for top spot in the Atlantic Division as the Rangers defeated Toronto 4-3 in a shootout. Meanwhile, Ottawa moved just one point behind the Boston Bruins for first place in the Northeast Division, though the Bruins now have three games in hand.
