For one night anyone, it felt like old times on Causeway.

With bad blood spilling all over the Garden between two teams that played a week ago, the Bruins sprinted to a 4-0 second-period lead and hung on for a 6-2 victory against divisional rival Tampa Bay.

Memo to the NHL: Let’s have more of this.

After making 39 stops for the win in Florida, Jeremy Swayman made a season-high 43 stops for the victory.

That’s a lot of shots, but this one didn’t feel like the theft that Saturday’s win in Sunrise did.

Both teams were missing key pieces. Charlie McAvoy is out for at least a couple of games with an undisclosed injury while Tampa star Brayden Point was scratched because he missed a team meeting.

But the biggest Bruin news of the day was the return of Matt Poitras. And he didn’t wait long to have an impact in the first period in which the B’s took a 2-0 lead.

Under duress from Charlie Coyle, Victor Hedman lost the puck just inside his left point position and Poitras pounced on it, bursting up ice on a 2-on-1. He smartly waited out Nick Perbix’s belly-flop slide and made a pretty pass around the defenseman’s skates to Trent Frederic for a redirection at 4:24, Frederic’s seventh of the year.

Parker Wotherspoon doubled the lead at 9;31 with his first career NHL goal in his 76th big league game. Operating high on the right wing, David Pastrnak found Wotherspoon on the left side and the journeyman absolutely sniped a wrist shot over Andrei Vasilevskiy’s blocker arm. Not a bad goal against whom to score your first career goal.

The Lightning started to push back and held a territorial advantage in the second half the period, boasting a 9-6 shot advantage.

But there was more good news to come in the second.

After surviving a 3-on-1 by Tampa after a Bruin power-play, Hedman’s missed shot rimmed around to Pastrnak, who moved it up to Brad Marchand and took off on a potential 2-on-1. From the left circle, Marchand whistled a wrist shot over Vasilevskiy’s glove arm at 1:13 of the second. It was Marchand’s 16th of the year and snapped a nine-game goalless skid for the captain.

The brief Nikita Zadorov-Mitchell Chaffee tussle produced a 4-on-4 situation and the B’s were the ones to take advantage of the open ice. Andrew Peeke made a nice cut into the slot and fired a shot that Vasilevskiy stopped but could not control the rebound. Ryan McDonagh couldn’t control it either and Pavel Zacha gathered the loose puck and fed Pastrnak for his 20th at 6:05.

Then came the slobber-knocker that had been brewing since Emil Lilleberg crosschecked Mark Kastelic in the face last week in Tampa. Frederic dropped the gloves with Lilleberg at 7:37 and it was a heavyweight battle. Frederic won on points as he pounded away at Lilleberg but, to the Bolt’s credit, he hung in there and threw some good shots himself.

The B’s won the fight, but not the rest of the period.

Meanwhile, Swayman had been good again. But he couldn’t do much about Tampa’s first goal at 8:50. After a Lightning faceoff win, Hedman snapped shot toward the net that Conor Geekie, Morgan’s brother, tipped home at 8:50.

And they couldn’t get out of the period with a three-goal lead as Hedman’s painful goal with 17 seconds remaining in the period cut it to 4-2.

After Nikita Kucherov gathered a blocked shot, he fed Hedman on the left side and the venerable D-man slipped it through Swayman.

Much to the B’s chagrin, it was a game again.

The teams weren’t done with the fisticuffs. Just 21 seconds into the third, Zadorov dropped them with Erik Cernak, with Zadorov scoring the take-down.

The B’s played much of the third in their own end and Swayman saw some rubber but the B’s protected the house well.

The B’s lost Cole Koepke at 9:23 when Darren Raddysh delivered a brutal hit to the head to the Bruin. It called for a five-minute major so it could be reviewed, but it was ruled there was no penalty and they played on. Cernak also got away with a greasy hit/elbow on Marchand shortly after play resumed.

The Bolts got their first power play with 3:33 left in regulation when Brandon Carlo dove for a puck and Bolt tripped over him. But off the faceoff, Peeke ripped the puck from the  bottom of the left circle and scored his first goal as a Bruin into the empty net.

Zacha then scored another one with 3:01 left and the B’s could finally breathe easily.
