PITTSBURGH — The only spark at Mellon Arena came on Chad Kilger's penalty-shot goal.

It was the only offense on a dark night in Pittsburgh.

Kilger scored on with 6:51 remaining Sunday night and Mikael Tellqvist made 21 saves in the Toronto Maple Leafs' 1-0 victory over the Pittsburgh Penguins that was delayed twice by blackouts.

Penguins president Ken Sawyer said there also was a small fire in an electrical panel about 30 yards behind a seating section, apparently related to the second blackout. The fire was not announced to the crowd, but hundreds of fans left the building and didn't return once the game was held up a second time.

Sawyer said the fire never reached an emergency level.

"It was a bizarre game, for sure," Kilger said. "But we played a consistent game and stayed focused through the whole thing."

The outcome was decided in one furious sequence.

Pittsburgh rookie Sidney Crosby burst in alone on Tellqvist and took a low wrist shot that skittered off Tellqvist's pads and went wide.

The Maple Leafs immediately countered and sprung Kilger down the left wing and into the Penguins zone. As he cut across the middle to attempt a backhand on goaltender Marc-Andre Fleury, defenseman Rob Scuderi tripped him. Referee Wes McCauley immediately signaled for a penalty shot.

Penguins coach Michel Therrien was furious at the call because he felt Kilger never was clearly behind the defense.
