PITTSBURGH — Pittsburgh Penguins coach Mike Sullivan wants his highly skilled team to find a comfort level in playing low-scoring, one-goal games as the Stanley Cup playoffs approach.

That message was received.

Tristan Jarry made 29 saves for his first shutout of the season and Jake Guentzel scored in the Penguins’ 1-0 victory over the Boston Bruins on Sunday.

“It was a hard-fought game and there wasn’t a lot of space out there,” Sullivan said. “You had to fight for every inch on both sides, and from that standpoint, it had a playoff feel. We knew we were going to fight for every inch, and we wanted to force (Boston) to do the same.”

Jarry has won his last four decisions, including a sloppy 7-6 home victory over New Jersey last week, in which he allowed six third-period goals. He rebounded two nights later against the Devils and has earned a point in 11 of his last 12 starts.

“It’s a short season and you play a lot of games,” Jarry said. “It’s a matter of being prepared for the next game.”

Guentzel scored his 21st at 4:03 of the third period to help the Penguins win their fourth straight.

Bryan Rust and Brian Dumoulin made a plays at the blueline and along the wall to keep the puck in the zone and get it to Sidney Crosby near the goal-line. Crosby set up Guentzel, who ripped a high slap shot past Jeremy Swayman’s glove from the left faceoff dot.

“That was a goal-scorer’s goal,” Sullivan said. “It was a great set up by (Crosby). Jake has the ability to do that for us.”

Pittsburgh has 14 wins and points in 16 of its last 19 games overall. The Penguins have 12 wins and points in 13 of their last 16 home games against Boston, dating to March 11, 2012.

Swayman stopped 28 shots for the Bruins. They lost their second straight following a season-long six-game win streak. The Bruins have nine wins in their last 14 games.

Swayman, the top college goaltender last season for Maine, has allowed more than two goals only once in his first seven NHL starts. In his past three appearances, Swayman has stopped 82 of 84 shots, including a shutout. Swayman is the fourth Boston goaltender the Penguins faced this season.

Crosby now has 16 goals and 64 points in 49 games against the Bruins.
