OTTAWA (AP) - Daniel Alfredsson scored his 30th goal and Dominik Hasek made 23 saves to lead Ottawa to a 4-3 victory over Toronto on Monday night, the Senators' second straight home win over the Maple Leafs in three nights.
Mike Fisher, Wade Redden and Bryan Smolinski also scored for Ottawa, which beat Toronto 7-0 on Saturday. The Senators, who have been eliminated from the playoffs by the Maple Leafs four of the last five seasons, improved to 6-0 against their provincial rivals this season and have outscored them 36-12.
Hasek has two of his four shutouts against the Maple Leafs.
Tie Domi, Kyle Wellwood and Nik Antropov scored for Toronto, which has lost six straight overall.
Toronto defenseman Carlo Colaiacovo sustained a concussion during the first period and was taken off the ice on a stretcher after his head struck the boards following a collision with Ottawa's Vaclav Varada 5:29 in.
The Senators got a pair of even strength goals in the first by Fisher and Alfredsson, who reached 30 goals for the third time in the last four seasons when he scored at 16:32 to make it 2-0 after Fisher opened the scoring with his 17th at 4:50.
Domi, who fought with Chris Neil shortly after Alfredsson's goal, drew Toronto to within 2-1 when he beat Hasek from the edge of the crease 8:09 into the second.
Redden restored Ottawa's two-goal lead with his eighth of the season on a power play 3:08 into the third, moments after Jason Spezza hit the left post.
Redden was erroneously given a delay of game penalty at 4:01 after he flipped a shot from the Senators' zone through the Maple Leafs' bench and into the crowd. Ottawa coach Bryan Murray complained while the penalty was announced. Redden had already sat in the box when referee Ian Walsh reversed the call, announcing to the crowd that the puck had gone into the Toronto bench.
Maple Leafs coach Pat Quinn argued the reversal to no avail and Smolinski scored his 10th shortly thereafter at 5:53 to put Ottawa up 4-1.
Domi assisted on Wellwood's goal at 11:37 and Antropov drew Toronto to within one with a power-play goal at 17:49.
The Maple Leafs lost Colaiacovo shortly after Fisher opened the scoring. The 22-year-old defenseman was about to hip check Varada, who appeared to recognize that at the last moment and attempted to avoid the hit. The collision sent Colaiacovo flying headfirst into the boards and he lay motionless on the ice following the impact.
Toronto head athletic therapist Kevin Wagner raced across the ice to attend to Colaiacovo, who had blood dripping off his head when it was lifted off the ice.
Ottawa team doctor Don Chow joined Wagner and paramedics on the ice. Colaiacovo was able to move his legs as he was being attended to. The 22-year-old Toronto player raised his right thumb to the crowd as he was taken off on a stretcher after having his head, neck and legs were stabilized.
