BOSTON — Joonas Korpisalo made 27 saves for his first shutout of the season and the eighth of his career, Viktor Arvidsson scored and the Boston Bruins beat the Pittsburgh Penguins 1-0 on Sunday.

The Bruins won for the fifth time in six games despite going 0 for 6 on the power play a day after beating the Rangers 10-2. It was Boston’s first shutout this season.

Coming off a loss at home against Calgary on Saturday that halted their season-high six game winning streak, the Penguins were shut out for the fourth time this season. Stuart Skinner stopped 17 shots.

Unlike Boston’s game a day before, this one was limited in high-quality scoring chances and didn’t have any whacky moments like when the Bruins were awarded a reviewed goal when most of the opponents were in their locker room at the end of the opening period.

Arvidsson’s goal came 11 minutes into the first when he had two shots at a rebound, outworking defenseman Erik Karlsson before lifting a backhander past Skinner from the edge of the crease.

The Penguins made a surge late in the second, with Korpisalo’s best save coming as he quickly slid across the crease to make a glove stop on Sidney Crosby’s backhander from the right circle.

Bruins forward Morgan Geekie, their leading goal scorer, missed the game due to a family matter. He left Saturday’s game after the opening period.

Pittsburgh’s Kevin Hayes played in his 800th career NHL game.

Linesman Matt MacPherson worked his 1,000th career NHL game and was honored with a brief pregame ceremony. Each team’s captain presented him with a signed jersey with his name and No. 1000 on the back.

SATURDAY

Flames top Penguins 2-1

PITTSBURGH (AP) — Matt Coronato scored in the third period to lift the Calgary Flames over the Pittsburgh Penguins 2-1 on Saturday.

Connor Zary also scored for the Flames, who won for the first time in 2026 and snapped a four-game losing streak. Calgary was limited to one goal in each of its previous three losses.

Devin Cooley stopped 27 shots in his first start since Dec. 20.

Egor Chinakhov scored for the Penguins, who saw a season-high six-game winning streak end. Pittsburgh had won seven of eight before Saturday’s loss. Arturs Silovs made 23 saves.

Thomas Novak thought he scored the tying goal in the third period, but it was ruled that Sidney Crosby interfered with Cooley.

Evgeni Malkin got his 854th assist to pass Bryan Trottier and Anze Kopitar for the 10th most assists in NHL history with one team.

Bryan Rust missed the game with a lower-body injury and is considered day-to-day.

Crosby’s eight-game point streak ended, and Erik Karlsson’s nine-game home point streak was also snapped.

Coronato scored the winning goal when he beat Silovs with a wrist shot 42 seconds into the third period.

Zary opened the scoring for Calgary with a breakaway goal at 2:33 of the first period. He intercepted an errant pass from Ryan Shea at the offensive blueline and beat Silovs between the legs.

Pittsburgh scored its only goal at 9:17 of the second period when Chinakhov finished a give-and-go with Malkin from the right faceoff dot.
