PITTSBURGH — The injury-ravaged Pittsburgh Penguins keep winning.

Sidney Crosby scored his 20th goal of the season Saturday, helping the Penguins win their season-high seventh straight game, 4-3 over the Calgary Flames.

“Winning always makes things better,” Crosby said. “There’s no secret there. It doesn’t matter what team you play on, winning solves everything.”

The Penguins, who lead the Eastern Conference with 55 points, played without star center Evgeni Malkin and five of their top six defensemen for the fourth straight game, but that didn’t stop them from winning their 10th straight at home and picking up their 12th victory in 13 games.

“We do our best to chip in and get through this,” Crosby said. “It’s not common, you’re not used to being in this situation, but just having the mindset of going out there to outwork the other team has done us well.”

Crosby, who had a goal and two assists, extended his season-high points streak to 10 games. He leads the league with 54 points. Pascal Dupuis added his seventh goal of the season, Harry Zolnierczyk scored his first with the team and James Neal added a goal.

Mike Cammalleri scored his first goal in nine games for the Flames. Jiri Hudler netted his 10th, and Paul Byron had the other goal. The Flames have lost four straight and six of their last nine.

“We never quit,” Flames coach Bob Hartley said. “We kept going at the net. With a little luck, maybe we could have gotten the tying goal. It’s a tough loss to swallow.”

Pittsburgh jumped to a two-goal lead and went up 4-1 on goals from Crosby and Neal. But Calgary scored twice — Cammalleri with 45 seconds left in the second period and Hudler 1:03 into the third period to make it 4-3.

The Flames came up empty on an ensuing power play and continued to press for the tying goal. Their best chance came with 6:25 remaining when Joe Colborne hit the post to the right of goalie Marc-Andre Fleury, who won his 21st game of the season.
