In each of the last two postseasons, Zdeno Chara and Dennis Seidenberg have skated together as the Bruins’ shutdown duo.

Based on their coupling in Thursday’s 2-0 blanking of the Lightning before 17,565 at TD Garden, it’s a good bet the strongmen will be back together again when the playoffs begin next week.

Chara and Seidenberg, asked to shut down Tampa Bay’s flammable line of Teddy Purcell, Steven Stamkos, and Martin St. Louis, fulfilled their obligations. Neither St. Louis nor Stamkos, the top two scorers in the NHL entering the night, recorded a point.

Chara, Seidenberg, and Tuukka Rask, three of the Bruins’ four most important players (Patrice Bergeron being the other), played a big part in keeping the explosive duo off the scoresheet. The one time Stamkos slipped free for a bona fide chance, Rask (30 saves) pushed to his left and flashed his glove at 12:20 of the second period.

“You could see that we feel comfortable with each other,” said Seidenberg. “We keep it simple. We talk to each other. We communicate well out there. It resulted in us shutting them down, for the most part. We gave up that one odd-man rush, but for the most part we kept them to the outside and kept them to not as many chances as they would have liked.”

For the first 45 games of the regular season, Chara and Seidenberg had played together only for stretches. The coaching staff’s concern about pairing Chara and Seidenberg is how top-heavy the six-man rotation of defensemen becomes.

But if the Bruins’ first-round opponent has a fearsome No. 1 line — the Islanders, for example, roll out Matt Moulson, John Tavares, and Brad Boyes — deploying Chara and Seidenberg together might be the best option.

“It’s pretty hard to contain that line because they’re so good,” coach Claude Julien said of Tampa’s top trio. “Two of those guys are in the top scoring in the league. You know they’re going to get some chances. You want to minimize it. Whenever there was a bit of a breakdown, Tuukka made some big saves. They’re a pair that’s done a good job in the past in the playoffs. They hadn’t played together this year. It was about giving them a feel and taste of it again. So if need be, when playoffs come around and depending on who we play, we may have that option as well.”
