More like their not-so-distant relatives from the last two seasons, the Bruins bounced back from 1-0 and 2-1 defeats on Saturday night and handed a 4-3 overtime loss to the Maple Leafs at TD Garden.

After putting intense pressure on the net with David Pastrnak, Brad Marchand hit a backhand from the doorstep to score the winner 2:26 into the three-on-three extra session. The victory, powered by Jeremy Swayman’s 20 saves, ended a three-game losing streak and lifted the Black-and-Gold to .500 (4-4-1) for the first time in two weeks.

Pastrnak (power play), Justin Brazeau and Mark Kastelic also scored for the Bruins and they hope to turn the win against the Flyers into something momentum-boosting on Tuesday night at Causeway Street.

Bruins, who had been superior in each of the previous three games, finished the night with a 34-23 advantage and achieved the biggest difference of the season. Center Charlie Coyle and defenseman Brandon Carlo were the only Bruins unable to get a shot on Maple Leafs goaltender Anthony Stolarz.

The Bruins were just 1:17 away from a 3-2 lead when Auston Matthews scored the equalizer. The Leafs’ best marksman broke through the low hole and redirected Mitch Marner’s 15-foot shot/pass form just inside the blue line.

After scoring just three goals in their previous three games (all defeats), the Bruins tied the game three times in the second period and took a 3-2 lead heading into the final period of the regular season.

The Leafs were the first to hit the net just 35 seconds into the first half and broke the scoreless tie. Matthews moved the puck in front of the net on a charge from the left half wall, and Matthew Knies intercepted a loose puck during his teammate’s attempt for a 1-0 lead.

The Bruins came back with the equalizer just over two minutes later, when Pastrnak hit a one-timer power play shot from the spot in the left circle. After attacking from the right post, Marchand shot diagonally over the hole.

The Leafs, who were a little more courageous this year, took the lead again, 2-1, with the sides skating by four. Morgan Rielly slid a step or two behind Marchand and cashed in on a one-timer from Matthews’ sure coverage.

The Bruins finally took the lead for the first time, as Brazeau and Kastelic connected on two shots just 36 seconds apart.

The big-bodied Brazeau, who also took part in the second power play unit, brought the score to 2-2 at 12:38. His was the last of three close-range shots, lifting a shot near the right post following attempts from Matt Poitras and Trent Frederic. Brazeau is difficult to pull off and has a deceptive touch; These are elements the Bruins often lacked in the bottom six last season.

Kastelic was all alone, parked near the right post, when Johnny Beecher sent a relay into the left corner at 13:14. Kastelic, who was acquired in the trade that sent Linus Ullmark to Ottawa in June, scored his third goal in the Black-and-Gold game. The 1.80-meter-tall center has never scored more than seven goals in a season.

The Bruins failed to score in the opening period, but their overall effort resulted in their best period of the season. Had their shooting eyes been sharper – especially Frederic, Poitras and Pavel Zacha – they could have finished the period two or three goals ahead.

But on the whole, it looked a lot like the Bruins teams that coach Jim Montgomery had guided to 112 wins in the previous two regular seasons. It is very different from the team that entered the evening with a 3-4-1 lead.

The only rough patch came midway through the period, starting with Morgan Geekie’s interference penalty with 10:34 left. With 32 seconds left on that infraction, the Bruins went two down after Beecher was ejected from the game for tripping.

With a manpower advantage over the course of 2:32, the Leafs put three pucks on net. A sharp Swayman handled it all with ease, making his fourth consecutive start.

Statistics can often be misleading, but the Bruins finished the period with a 25-12 lead in shot attempts. No funny math. The Bruins had a clear edge in territorial advantage and desire to shoot the puck. In the Toronto net, the 6-6 Stolarz made some nifty stops.
