OTTAWA -- The Toronto Maple Leafs won't go away quietly.
Alexander Mogilny scored the game-winner at 4:28 of the third period as Toronto beat the Ottawa Senators 4-3 on Sunday to force a decisive Game 7 of the Eastern Conference semifinal series.
Game 7 is Tuesday night at Toronto.
Gary Roberts, continuing his prolific postseason production, had two goals and an assist to help send the Maple Leafs to their second seventh game of the playoffs. Toronto outlasted the New York Islanders in the first round.
Bryan McCabe also scored for Toronto. Marian Hossa, Daniel Alfredsson and Todd White scored for the Senators, who squandered a two-goal lead.
The Senators are 2-1 in Toronto in the series, but Ottawa has never advanced past the second round in its 10-year history, and has been eliminated by Toronto in the past two playoffs.
It was quite a turn of events for Mogilny, who had not only been limited to two assists against the Senators, but who's errant pass through the middle led to Alfredsson's goal that gave Ottawa a 2-0 lead.
Mogilny ended a five-game goal drought a day after he told reporters, ''I've got a feeling it's coming. I've just got a feeling that something good will happen soon.''
From deep in the Ottawa end, Radek Bonk's pass through the middle hit off of teammate Martin Havlat's skate. Toronto's Travis Green got to the loose puck, and slipped a pass to Mogilny, who was alone behind the defenders.
Turning toward the net, Mogilny snapped a shot that beat goaltender Patrick Lalime on the stick side.
The Maple Leafs won despite missing six regulars, including captain Mats Sundin (broken wrist) and forward Darcy Tucker, who broke a bone in his shoulder and a dislocated his left shoulder during a disputed play that settled Game 5.
Seconds after hitting Tucker from behind into the boards, Alfredsson scored the game-winner. The Maple Leafs complained that Alfredsson should have been penalized for the hit on Tucker.
Curiously, a boarding penalty against Ottawa's Ricard Persson changed the complexion of Sunday's game.
The Maple Leafs had been thoroughly outplayed -- outscored 2-0 and outshot 8-1 -- through the first 12 minutes when Persson hit Tie Domi from behind, sending the Toronto forward face-first into the boards.
With Domi cut over the left eye, Persson was issued a five-minute major penalty and ejected from the game.
The Maple Leafs capitalized, with McCabe and Roberts scoring power-play goals 4:19 apart to tie the game.
After Roberts put the Maple Leafs ahead 13:09 into the second period, the Senators tied it on White's great individual effort, in which he bulled through two Toronto defenders, to score with 24.7 seconds left in the second.
The four goals are the most the Senators have allowed this postseason. The Senators have now squandered leads in each of their last three games.
And it didn't help that they were missing hulking defenseman Zdeno Chara, who sprained his left knee late in Game 5. The Senators were then down to five defenseman when Persson was ejected.
Leafs goalie Curtis Joseph, who stopped 30 shots, preserved the victory, and also get help from his goal posts.
With 10:40 remaining, Ottawa's Benoit Brunet -- parked in the slot -- slapped a bouncing puck off the left post. Ottawa's Steve Martins ripped a shot off the post in the second period.
Joseph's best save came with 8:14 left, when he went down to foil Bonk driving up the right side.
