BOSTON — At first, the Bruins looked like the team that we’ve been used to seeing. They were physical, they got a couple shots towards Lightning goalie Dwayne Roloson and they had a little bit of jump to their game.

But midway through the first period, the Bolts capitalized on some Bruins’ miscues in their own end, striking with three goals in 1:45, beginning with Sean Beregenheim’s eighth tally of the postseason off a Dennis Seidenberg turnouver at 11:15. Tampa defenseman Brett Clark struck 19 seconds later as his shot snuck through Tim Thomas’ blocker at 11:34 and 66 seconds after, Teddy Purcell took advantage off a Tomas Kaberle blunder at 12:40 to give the Bolts a quick 3-0 lead.

“Well, it was a lot of little breakdowns,” Seidenberg said about the Lightning’s first period markers. “We gave them those goals to score in the first period, and that’s not us and we all know that. We just have to clean that up and we’ll be fine.”

Though Boston generated a little momentum after Tyler Seguin’s first career postseason goal, the trio of goals paid dividends for Tampa as they cruised to a 5-2 victory in Game 1 Saturday night at the TD Garden.

“It’s tough. We pretty much gave them every single one of them, and we never gave up after,” Kaberle said. “We know we are better in here and we have to show it in the second game.”

“Of the first three goals, I don’t feel like there was a good goal out of all of those,” head coach Claude Julien added.

This situation should sound familiar to Bruins fans going back to the Montreal series.

After some costly turnovers in the first two games, the Bruins couldn’t generate any momentum and were a little resistant to shoot the puck, much like they were Saturday in Game 1. Though the Lightning did a good job at blocking shots, particularly on the power play, the Bruins seemed a tad hesitant to throw some rubber at Roloson.

“We knew we had tons of time left and everyone was trying to stay positive,” Seguin said about the team’s morale after they gave up the first three goals. “But three goals in the first period…that’s not our style. That’s not Bruins hockey so that’s something we’re going to fix for the next game.”

Given the circumstances, the Bruins are hoping to avoid dropping the first two games to the Bolts Tuesday night.

“Obviously we lost Game 1 as well well and we have to make sure we are on top of them in Game 2,” Kaberle noted. “We need to dumpt the puck in and make hard, strong plays and put everything at the net and get some traffic.”

Though the Bruins and Bolts have only played in one game this series, there has already been many references to the Montreal series on their ability to bounce back. They’ve been through this before and they can use the loss as a lesson going into Tuesday’s contest.

“I think we’re going to take this in tonight and take in the loss right now,” Seguin said. “But it’s heads high and we have a new game Tuesday. It’s going to be a long series so we’re going to start getting prepared for that tomorrow morning.”
