The center became the 63rd player in NHL history, and fifth active, with at least 1,100 points when he scored with a wrist shot from the right face-off circle on a power play, extending Pittsburgh's lead to 3-1 at 11:40 of the second period. Malkin has 424 goals and 676 assists in 935 NHL games, and 12 points (four goals, eight assists) during an eight-game point streak.
"[Malkin] is a guy that I think relies so heavily on his confidence level, and he puts a lot of pressure on himself to produce offensively for our team," Penguins coach Mike Sullivan said. "He's playing a strong game right now. Obviously, he's a dominant player for us. You just notice him every time he's on the ice. It feels like the puck follows him around. That's when you know he's on his game."
Tristan Jarry made a season-high 42 saves, and Sidney Crosby extended his point streak to seven games (four goals, seven assists) with a goal and two assists for the Penguins (18-9-1), who have won six in a row.
Matt Grzelcyk scored, and Jaroslav Halak made 22 saves for the Bruins (14-8-4), who have lost four of five (1-3-1).
The teams will conclude a back-to-back set here Tuesday.
"[We] generated enough to win the hockey game," Boston coach Bruce Cassidy said. "You have to finish. I know that, so stating the obvious here. But I'm more concerned when you don't generate. Obviously, it means you're not doing the right things to get the opportunities, so you continue to generate. I believe there's enough talent there to get enough goals."
Grzelcyk put Boston ahead 1-0 at 6:47 of the first period with a wrist shot off the left post on a power play with Nick Ritchie providing a screen. It was Grzelcyk's first goal since the final game last regular season.
"I feel pretty confident. I think my legs are there," said Grzelcyk, who has played 13 games this season, missing all but one game in February with two separate injuries. "I'm a much better player when I'm able to skate. I'm just trying to make quick plays, get it up to our forwards and let them go to work down low. I think we got a nice start there of having more of an attack mentality. That's encouraging to see, for sure."
