Senators 3, Maple Leafs 2

OTTAWA  - Daniel Alfredsson scored twice, including the game-winner on a power play with 4:59 remaining, to lift the Ottawa Senators to a 3-2 victory over the Toronto Maple Leafs on Thursday night.

Alfredsson put a wrist shot over Vesa Toskala's right shoulder into the top left corner for his third goal of the season and helped Ottawa regain the lead after blowing a two-goal lead in the second.

Dany Heatley assisted on Alfredsson's opening goal 8:18 into the game before he scored on a power play at 13:06 of the second to put Ottawa up 2-0.

Mats Sundin and Matt Stajan scored goals 32 seconds apart later in the period as Toronto tied it with 3:44 left.

Martin Gerber made 41 saves for the Senators, who beat their provincial rivals for the second time in two nights. Toskala stopped 26 shots in his Toronto debut.

Alex Steen had an apparent goal waved off midway through the second period that would have tied the game at 1-1 for the Maple Leafs. Jason Blake drove to the net and collided with Gerber before Steen poked the loose puck under Gerber's pad and into the net at 10:35.

Referee Chris Rooney waved his arms and, after a brief delay, the goal was disallowed.

Ottawa's Chris Neil was penalized for diving as Alex Ponikarovsky was sent off for tripping at 15:47, just three seconds after Sundin scored his first of the season at 15:44 of the second to draw the Maple Leafs within 2-1.

Stajan tied it at 2-2 when he scored a short-handed goal at 16:16.
