ST. LOUIS — Paul Stastny and the rest of the Blues’ top line turned in a clutch performance Monday night.

Stastny had a goal and three assists, and linemates Alexander Steen and Troy Brouwer each added a goal and an assist for St. Louis in a 5-2 victory over the Pittsburgh Penguins.

“We talked a little bit before the game that the last few games we’ve been a little bit stagnant,” Brouwer said, “so we wanted to be a difference-maker tonight and we were.”

Stastny’s four-point game, his first since signing with the Blues before last season, fueled the line’s eight-point effort.

“I think we just work for each other,” Stastny said. “We’re getting more and more comfortable. I think we’ve had chances and today they started falling.”

Vladimir Tarasenko and Kevin Shattenkirk also scored for the Blues, who have won four of five following a five-game losing streak. Brian Elliott followed up his career-high 46 saves Saturday by stopping 36 shots against Pittsburgh.

“He’s competing at a very, very high level now,” St. Louis coach Ken Hitchcock said. “He’s taking advantage of a situation that was thrust upon him, but his competitive level’s as high as I’ve seen it right now. It’s really good to see.”

Evgeni Malkin and Chris Kunitz scored, and Kris Letang had two assists for the Penguins. They have lost three of four and five of seven. Jeff Zatkoff, making his first start since Dec. 31, stopped 20 shots.

“We didn’t execute like we wanted to,” Penguins center Sidney Crosby said about his team’s play in the third period. “Especially after we did in the first and second. We need to give a bigger push than that with a tied game in the third. They were better in the third, I thought. The first two periods we gave ourselves a good chance, but the third period was kind of the story of the game.”

Steen scored first, with 8 minutes left in the opening period, after Zatkoff left the crease to challenge Brouwer for a puck. Stastny then fed a pass in front and Steen, who hit the post earlier, buried it for his 14th of the season.

The Penguins tied it with Kunitz’s eighth of the season, on a breakaway after a spring pass from Letang.
