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 goal of the season 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 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 winning 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 last three appearances, Swayman has stopped 82 of 84 shots, including a shutout. He is the fourth Boston goaltender the Penguins faced this season.

“Those are crucial points and it was a tight game all around,” Swayman said. “It’s what we’re going to expect in a couple weeks. It was a fun game to be part of, but just disappointed that we didn’t come out with the two points.”

PLAYOFF PUSH

Pittsburgh and Boston are battling for two of the top four spots in a tightly-contested East Division.

The Penguins have a two-game series against the Washington Capitals after Tuesday’s home game against the Bruins.

“It’s two teams trying to fight for the playoffs just to get in,” Guentzel said. “These are two crucial points, and Tuesday is another big one for us. We have to make sure we’re ready.”

Just two of Boston’s final nine games are against teams currently holding a playoff spot. Four of Boston’s final nine are against the New Jersey Devils or Buffalo Sabres, the two bottom teams in the East Division, while the other three are at home against the fifth-place New York Rangers.

TIGHT CHECKING

The game was scoreless through two periods.

Both teams had 10 shots in the first period, but Pittsburgh outshot Boston 11-8 in the second as the Penguins started to gain control in the later stages of the period. Boston blocked 10 shots, while the Penguins had six blocks, and neither team went on the power play until Boston’s Patrice Bergeron was called for high-sticking was less than two minutes remaining in the game.

“Our work ethic was OK,” Bruins Coach Bruce Cassidy said. “We didn’t manage the puck great early on, but we fixed that. Both teams had to work for every inch of ice out there.”

CROSBY SECOND AGAINST THE BRUINS

Crosby passed Jaromir Jagr for the second-most points all-time by a Penguins’ player against Boston.

Crosby now has 16 goals and 64 points in 49 games against the Bruins, trailing only Mario Lemieux, who finished with 73 points against Boston. No active player in the NHL has more points against Boston than Crosby, who has five goals and 24 points in his last 19 games against the Bruins.

On Saturday, in a win against New Jersey, Crosby joined Wayne Gretzky as the only players in NHL history to register a point-per-game season in each of their first 16 years in the league. He also passed Lemieux and Evgeni Malkin for the most 20-plus goal seasons in franchise history.
