David Pastrnak became the fifth Bruins player to score 40 goals in consecutive seasons as the Bruins remained on pace for a history-making season with Monday's 3-1 win over the Ottawa Senators.

Pastrnak scored twice, breaking the second-period tie to move beyond the 40-goal mark for the third time in his career.

The win improved the NHL-best Bruins' record to 43-8-5, extending their current win streak to four games.

Boston are currently on pace for 62 wins, which would match the record held by the 1995-96 Detroit Red Wings and the 2018-19 Tampa Bay Lightning.

The Bruins are also on pace for 133 points, which would exceed the record held by the 1976-77 Montreal Canadiens.

Boston also tied the 1979-80 Philadelphia Flyers for the fewest games to reach 90 points in NHL history.

Bruins center David Krejci, who brought up his 1000th game, said the challenge for the team was to not mentally let standards slip.

"We're at that point in the season where it's mental," Krejci told reporters. "We all know what we can do in this room, and we've got to be mentally prepared for each game.

"We hit a little tough patch maybe a couple of weeks ago, but we're a good team. We've got good guys on the team, and we talk about it.

"Like I said, it's mental. We've just got to get ready for those games. We've got to stay sharp because it is not easy.

"This is the time of the year that if you let up, it can get away from you pretty easily, so we've got to stick together, grind it out and be mentally sharp."
