Alfredsson scored his 30th goal and Hasek made 23 saves to lead Ottawa to a 4-3 victory over Toronto on Monday night, the Senators' second 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 Toronto this season and have outscored them 36-12.
"I think we're ready to play them when the puck drops and we're expecting a battle for 60 minutes," said Alfredsson, who has scored eight goals against the Maple Leafs. "When we do play 60 minutes, we're a tough team to beat."
Hasek has two of his four shutouts against Toronto.
Tie Domi, Kyle Wellwood and Nik Antropov scored for the Maple Leafs, who have lost six straight overall.
"We played a lot better and so that has to be looked at as an improvement, especially over Saturday night," said coach Pat Quinn, whose job security has been the subject of speculation among the Toronto media over the weekend. "We weren't that bad in the other games but it was not good enough to win, I guess. But the effort was better."
Maple Leafs 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.
"I don't think they saw one another," Alfredsson said.
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.
"Maybe it's not as big a benchmark as it used to be a few years ago but it's nice and I think there's more to come," Alfredsson said.
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.
"It's never happened before," Redden said of his brief banishment. "I guess there was a little confusion on everyone's part."
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 the Maple Leafs to within one with a power-play goal at 17:49.
"It was a better effort but we still didn't get the job done," Domi said.
Toronto 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.
Quinn felt that Varada was responsible for the injury.
"They said it was inadvertent but if you check it and look at it, it wasn't inadvertent," Quinn said. "He took the kid's feet out."
Varada, who was cut as a result of the collision and had stitches in and around his left eyebrow, said Colaiacovo was lining him up for a hit even though Senators center Chris Kelly was carrying the puck on the play.
"He wanted to hit me. He thought I was going to pick up the puck but I didn't," Varada said. "I was turning around and he didn't stop. I thought he tried to hit me. It could have been me lying there like that."
Maple Leafs 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.
Notes: Colaiacovo returned to Toronto with the team. ... Maple Leafs D Wade Belak and Senators RW Brian McGrattan fought in the second. ... The crowd booed the Liberal party's lead when early results of the Canadian election were shown on the scoreboard during the third period. The reaction turned to mild applause when results late in the period showed a slight lead for the Conservative party. ... Alfredsson had a career-high 37 goals in 2001-02 and 32 in 2003-04.
