With one last chance to hang a loss on the Bruins in the regular season and likely first round playoff series looming, the Toronto Maple Leafs came into the Garden seemingly intent on making some kind of statement.

The only message that was delivered, however, was that the Leafs still had no solution to the Bruins.

The B’s scored three second period goals to pull away and beat the Leafs, 4-1, in a hard-hitting affair that had to make the 2011 Stanley Cup team, the night’s honorees, crack a little bit of a smile. The B’s completed the four-game season sweep of the Leafs and notched their seventh straight win over Toronto.

In an emotion-filled first period, the B’s took a 1-0 lead but, thanks to Toronto goalie Joseph Woll, the Leafs kept any further damage at bay in the opening 20 minutes.

It seemed Toronto’s early strategy was to go at Brad Marchand. Calle Jarnkrok gave him a good, clean check at the Boston blue line early in the game. Then, after a pending interference call coming on Jake McCabe, Matthew Knies just leveled Marchand behind the net with a hit that was far from clean. After the ensuing scrum, the B’s were rightly given a two-minute 5-on-3.

They needed nearly all of it to take advantage. At 5:37 with 17 seconds left on the two-man power-play, Jake DeBrusk found David Pastrnak for a backdoor goal for his 39th of the season.

The B’s had several chances to build on that lead in the hard-hitting first. First, Trent Frederic deflected a Morgan Geekie feed just wide. Then Woll made a great stop on a play that would have led most of the hockey highlights. Mason Lohrei dangled through Morgan Rielly and then made a nice backhand pass to Justin Brazeau at the top of the crease but Woll was able to kick out his redirect.

Thanks to a handful of lost defensive zone faceoffs, it appeared as though the Leafs were poised to tie the game early in the second period. But when William Nylander did one too many dipsy-doo moves near the blue line, Trent Frederic made him pay. Frederic swiped at the puck and, whether he got it or not, Nylander lost it and Frederic took off on a breakaway with Nylander in hot pursuit. From the high slot, Frederic beat Woll with a low wrister between the pads at 4:16. It was Frederic’s 17th, tying his career high he set last season.

But trouble was awaiting.

In a net-front battle, Tyler Bertuzzi and Charlie Coyle were going at until Coyle went high on Bertuzzi and the short-term Bruin hit the deck. Coyle was given a pair of minors and the B’s had four minutes to kill. They killed off the first penalty but got too cute on the second one. Marchand and Danton Heinen played around with the puck at the Toronto blue line Heinen’s return pass to Marchand was too far. Timothy Liljegren made a smart read and sent Mitch Marner off on a breakaway, which he buried past Jeremy Swayman’s blocker at 7:56.

Emotions continued to run hot, with Bertuzzi and Parker Wotherspoon squaring off (Bertuzzi getting the unanimous decision). Then the B’s did not like a Noah Gregor’s leg trip on Charlie McAvoy and Geekie took a roughing penalty to nullify the power play.

It didn’t matter. Toronto took a high-sticking penalty during the 4-on-4 and, after 4-on-3 time expired, Geekie came out of the box and gave the B’s their two-goal lead back off a Kevin Shattenkirk feed at 17:16 on the 5-on-4, his 15th of the year.

Then they pushed the advantage to three goals 1:07 later when Brandon Carlo’s blue line shot got past Woll, is fourth of the season.

The attempted message-sending by the Leafs continued into the third. After the B’s killed a penalty, Max Domi roughed Marchand along the board and yet another scrum materialized. As the skaters were going at, Swayman came out to the neutral zone and signaled to Woll to get it on but the Leaf goalie stayed in the net.

The  Leafs never got closer on the scoreboard but Domi went after McAvoy one more time with 1:31 left. It did nothing to change the result.
