Joonas Korpisalo made 20 saves for his first shutout of the season and fifth of his career to lead the Boston Bruins to a 3-0 victory over the Philadelphia Flyers on Saturday.

Matthew Poitras, Justin Brazeau and Brad Marchand scored for Boston, which won for only the second time in its last six games.

Korpisalo was particularly active in the second period, making several athletic saves to keep the Flyers off the scoreboard and end Philadelphia’s two-game winning streak.

Poitras opened the scoring for the Bruins midway through the first period when he backhanded his first goal of the season from a difficult angle to the side of the net past Aleksei Kolosov.

Kolosov made 20 saves in relief of Sam Ersson, who left the game with an undisclosed injury in the first period.

Brazeau extended the lead to 2-0 at 11:23 of the second when he fired a shot from the right circle past Kolosov.

Marchand, who contributed to Brazeau’s goal, added an empty-net goal to cap the scoring.

Bruins: After being shut out at home against Philadelphia and a blowout loss in Carolina earlier in the week, Boston scored one goal. The Bruins controlled the game for much of the first period, outshooting the Flyers 14-5. They played most of the period in Philadelphia’s half and were eventually rewarded with Poitras’ goal.

Leaflets: Morgan Frost was thought to be a guy the Flyers would want to partner with Rookie sensation Matvei Michkov to create offense this season. It didn’t work and Frost doesn’t even play on the same line. Frost hasn’t scored a goal this season and had two chances Saturday that went wrong. One hit the post and another was saved on a sprawling save from Korpisalo.

Ersson left 7:36 into the first period and was replaced by Kolosov. Ersson appeared to have a skate issue during the previous save that was being repaired on the ice, but he was removed from the game at the next whistle. The Flyers announced he would not return. Before his injury, Ersson made eight saves on eight shots and looked sharp while withstanding a lot of offensive pressure from the Bruins.

121 — The number of shots blocked by Flyers forward Ryan Poehling since the start of last season, the most of any NHL forward.

Bruins: Return home Sunday for a quick turnaround against Seattle.

Leaflets: Until Tuesday, when they begin a three-game road trip to Carolina.
