Bruins right wing David Pastrnak, left, seen celebrating his goal with Jake Debrusk in Boston’s win over Anaheim last month, is second in the NHL in scoring with 12 goals and 12 assists for 24 points.

Bruins coach Bruce Cassidy appeared satisfied with the way his team performed in October following a Halloween practice at Warrior Ice Arena in Boston.

The reigning Eastern Conference champions finished the month tied for first place with the Buffalo Sabres with 20 points and a game in hand. The Bruins are 9-1-2 overall — 5-0-1 at home and 4-1-1 on the road — and are riding a four-game win streak.

“There will always be stuff that pops up but in general the state of our game recently has been good,” Cassidy said. “Now we have to stay sharp and develop chemistry and there are always things we can improve on.”

David Pastrnak (12-12-23) is second in the NHL in scoring while linemate Brad Marchand (7-14-21) is fifth, three points ahead of Washington’s Alex Ovechkin (11-7-18). Tuukka Rask is the NHL’s top goalie at 8-0-1 with a league-best 1.41 goals against average and a .951 save percentage.

The Bruins have the league’s best power play with 13 goals in 42 man-advantage situations for a 31% success rate. The Bruins penalty kill is 10th overall (83.8%) but improves to fourth (90.9%) on Garden ice.

“I think our players recognize that there is a lot of work that goes into it and we are not anywhere near our ceiling so they are good that way,” Cassidy said.

The Bruins will look to carry their good play into November when they host the Ottawa Senators on Saturday night at the Garden. The Bruins play 14 games in November, with three back-to-back sequences starting at home with the Penguins on Monday and at Montreal on Tuesday.

Miller time

Injured defenseman Kevan Miller has been making steady improvements and could begin contact practice by the middle of next week.

Miller has been out of service since suffering a fractured kneecap last April. He was wearing a red non-contact jersey in practice and his timeline to return to action is still unclear. Additionally, reclaiming a roster spot is not assured given the way Matt Grzelcyk and Conner Clifton have meshed on the third unit.

“He’s progressing well and he looked good out there but there is still a timeline and I don’t think he would be available for the next three games anyway,” Cassidy said.

Right with left

Cassidy prefers to employ his younger players on their strong side, but Danton Heinen has been the exception to that rule.

Heinen is a left-handed shot on the right flank of the Bruins’ second line with David Krejci (right) in the middle and Jake DeBrusk (left) on the left. Heinen has averaged 13:21 minutes in 12 games with two goals and two assists. He also plays on the Bruins’ second power-play unit.

“I prefer those younger guys on their strong sides and he’s still young but he’s not a kid anymore,” Cassidy said. “He’s gotten better at knowing where the pressure is coming from on his off wing and he can manage the puck better.”
