The Senators, who broke a three-game losing streak, also got a goal from Chris Neil. Ray Emery made 43 saves, including a point blank stop on Mikael Samuelsson with 2:39 remaining. Robert Lang and Pavel Datsyuk got the goals for Detroit, which had its three-game winning streak snapped. Dominik Hasek made 19 saves.
It was Hasek's first game against the team he played for last season.
He didn't play again after injuring his groin in the Olympics. Ottawa wasn't happy that Hasek didn't return for the playoffs, and did not re-sign him. Hasek then signed a one-year free agent contract with the Red Wings.
Five goals came in the second period, after a scoreless first in which Detroit outshot Ottawa 18-3.
Spezza opened the scoring 1:44 into the middle period, when he intercepted Lang's cross-ice pass at the Ottawa blue-line, went in on Hasek for a breakaway and beat him with a move and backhand shot. Neil made it 2-0 with a power-play goal at 5:19, when he tipped Christoph Schubert's shot from the point out of mid air for his ninth goal.
Spezza's second goal, his 17th, also came on the power play. He picked up the puck at the Detroit blue line and skated through all four Red Wings on the ice, beating Hasek with a forehand shot.
But Lang atoned for his giveaway just 25 seconds later when he beat Emery on a one-timer from the right face-off dot for his eighth goal. Datsyuk closed the gap to 3-2 with a power-play tally with 2:26 left in the second period. He also scored on a one-timer from the right face-off dot.
Emery's best save came on Datsyuk with about four minutes remaining in the second period.
With Emery down, Datsyuk appeared to have a wide open net as he got off a shot during a goal-mouth scramble. But Emery stretched out his glove hand for a spectacular save.
