Powered by a perfect special teams night, the Bruins got themselves back in the win column Monday night, as Jim Montgomery’s squad dropped the Blues by a 3-1 final at TD Garden.

“I mean, our special teams won the game,” Montgomery said after the win. “Our power play was 2-for-2, and our penalty kill was 3-for-3. Great work by both coaches, [Joe] Sacco and [John] Gruden.”

And Sacco’s contributions got a workout early into this contest.

On the kill three times in the opening 11 minutes of play, the Bruins not only went 3-for-3 on the penalty kill out of the gate, but limited the Blues to just three shots.

And when the tables finally turned and the Bruins found themselves on the man advantage following Niko Mikkola’s interference against David Krejci, the Bruins needed just 17 seconds and one shot from Jake DeBrusk to put themselves out front on Jordan Binnington and the Blues.

But in a middle frame that titled the Blues’ way, it was Brayden Schenn who took advantage of some miscommunication in the defensive zone by the Bruins and knotted things up at 1-1.

On the play, it appeared that Mike Reilly motioned to a backchecking Taylor Hall to take care of Jordan Kyrou, but Hall did not and both he and Reilly got caught in no man’s land while the Blues struck on Linus Ullmark.

The good news for the Bruins? It would be the only St. Louis goal of both the period and the game, as Ullmark made some fantastic second-period stops on chances from Kyrou and Robert Thomas, and finished with saves on 25 of the 26 shots thrown his way in the victory.

But the Bruins needed another marker before Ullmark could light the proverbial victory cigar, and it came with the Black and Gold’s second power-play opportunity of the evening.

With Ryan O’Reilly in the box after tripping David Pastrnak, Patrice Bergeron stepped up and from his normal bumper spot, as he rifled a beauty through Binnington with 7:15 left in the contest.

The Bruins almost immediately built on that with a Trent Frederic goal, too, scored just three and a half minutes later, and the Blues were cooked on the way to their seventh straight defeat.

Craig Smith made his return to the B’s lineup after missing the previous three games due to an upper-body injury. With Smith back in action, A.J. Greer sat as Boston’s healthy scratch up front, and was joined by defenseman Anton Stralman, with Jakub Lauko reassigned to the P-Bruins prior to Monday’s contest.

The Black and Gold’s victory improved the team to 7-0-0 on Garden ice to begin the 2022-23 season.

The Bruins will return to action Thursday night against the Flames.
