PITTSBURGH -- The Chicago Blackhawks could surely be forgiven if they held their collective breath Saturday night when No. 1 goaltender Corey Crawford was lying on his back next to his net after a collision.

And again when he left the game against the Pittsburgh Penguins a few minutes later after consulting with trainer Mike Gapski.

Crawford might have been the only member of the organization who wasn't overly concerned.

"I think it was just more precautionary. ... It wasn't bad at all," said Crawford, whose absence turned out to be brief.

He finished with 35 saves to help Chicago maintain its dominating stretch against the Penguins with a 2-1 win at PPG Paints Arena.

Artem Anisimov scored the go-ahead goal and Gustav Forsling also scored for Chicago (10-8-2), which has won eight in a row against Pittsburgh, including a 10-1 pasting in the teams' first meeting this season on Oct. 5.

Anisimov's goal in the second period came 21 seconds after Matt Hunwick scored short-handed to tie it for the Penguins (11-8-3).

It was the first home regulation loss for Pittsburgh, which is 6-1-1 at PPG Paints Arena.

Crawford left at 8:43 of the second period after he got clipped by Evgeni Malkin.

Crawford had left the crease and was near the left post when Malkin flew past. It appeared Malkin's knee made contact with Crawford's head. Malkin got a minor goalie interference penalty.

In his brief appearance, backup Anton Forsberg did not face any shots.

Pittsburgh goaltender Matt Murray made 36 saves, including 11 with his team shorthanded.

Both of Chicago's goals came on the power play, a 2-for-5 night. The Blackhawks are 5-for-13 with a man-advantage over the past three games after going 0-for-11 in the previous three.

"The power play comes up with a big night for us," Chicago coach Joel Quenneville said. "We expect it to be more effective than it's been. You get a goal and you can get some momentum off it. Those goals held up."

That is why Pittsburgh wasn't thrilled that it took six penalties. It has been shorthanded 23 times over the past five games.

"The more penalties you take, the more stress it puts on your penalty killers, and it takes the guys who don't kill out of your game as well," Murray said. "We've got to clean that up. It's tough when you're killing penalties every game. It kind of kills your rhythm as a team. We need to be more disciplined that way."

Forsling got the only goal of the first period. Off a faceoff, he launched a shot from the inner edge of the left circle that squirted through Murray's pads at 12:32.

Rookie Alex DeBrincat's assist on the goal extended his point streak to four games.

The Penguins tied it at 8:00 of the second period on Hunwick's short-handed goal.

Hunwick, who had missed the previous 15 games because of a concussion, sneaked in a short-side shot from the lower half of the right circle on a shot that was really a pass aiming for teammate Tom Kuhnhackl in front. Riley Sheahan got the only assist, giving him a three-game point streak.

"It was just a pretty simple play," Hunwick said. "Riley had it on the wall. I had just come on the ice, so I figured I'd leak in there. I think some of their guys were changing. He made a good pass over to me. I was just trying to get it to Tommy on the weak side, and got a fortunate bounce, but we'll take it."

The emotion Pittsburgh got from the goal didn't last.

On the same Chicago power play, Anisimov lifted the puck just inside the left post to restore the Blackhawks' lead at 8:21.

Anisimov said Pittsburgh's shorthanded tying goal did not make a dent in the Blackhawks' resolve.

"No. What happened, happened," he said. "Just forget that, learn from the mistakes and go forward. Just go out there and play power play."

The Penguins thought they tied it at 11:33 on a shot by Jake Guentzel, but it was ruled that defenseman Olli Maatta interfered with Crawford, nullifying the goal.

"There was no way (the goal was going to stand)," Crawford said. "He was in the crease and stuck his leg out."
