Losing Jonathan Toews gave Chicago energy.

It gave the Blackhawks motivation.

It gave them focus.

Gave them almost everything, it seemed, except a victory.

Mostly because Penguins goalie Marc-Andre Fleury wouldn't allow it.

Fleury stopped 25 shots in the Penguins' 4-1 victory against Chicago Sunday night at Consol Energy Center, and did most of his best work in the final 33½ minutes of play, after Toews was injured on a hit by Penguins defenseman Brooks Orpik.

"[Fleury] made a couple of huge saves for us to keep us in there," early in the third period, Orpik said.

After a fairly uneven effort through the first half of the game, the Blackhawks responded to the loss of their captain because of an apparent injury to his left arm or shoulder with a furious surge, but couldn't get a puck past Fleury when they still had a chance to extend the game beyond 60 minutes.

"He made a toe save on a rebound and [stopped] a couple of secondary opportunities," Penguins center Sidney Crosby said. "You need those saves to win games, especially against a good team like that. He was really solid for us."

Chicago was controlling play so thoroughly that on a stoppage in play midway through the final period, coach Dan Bylsma had a fairly animated, by his standards, and one-sided discussion with his players about how much time they were spending in their own end.

"Dan kind of gave it to us halfway through the period," Orpik said. "And I thought we responded pretty well."

Crosby punctuated that response with two late goals, making it 3-1 at 15:09 and hitting an empty net at 18:44 to close out the scoring.

The victory raised the Penguins' record to 48-22-5 and sliced their magic number for clinching first place in the Metropolitan Division to two. Philadelphia is the only Metropolitan team with a mathematical chance of overtaking them.

Whether losing two points to the Penguins truly will hurt the Blackhawks is conjecture; they are pretty well locked in to a first-round matchup against Colorado, although home-ice advantage hasn't been settled.
