RALEIGH, N.C. — Chris Wagner and Brad Marchand scored 5:07 apart in the second period, and the Boston Bruins beat the Carolina Hurricanes 2-1 on Tuesday night to take a 3-0 lead in the Eastern Conference final.

Tuukka Rask stopped 35 shots for the Bruins, who have won six straight postseason games for the first time since 1978. They are one victory away from their third Stanley Cup Final appearance in nine years.

Boston will go for the sweep on Thursday night.

Calvin de Haan scored and Curtis McElhinney made 29 saves for the Hurricanes while starting in place of Petr Mrazek, who allowed 10 goals in the first two games of the series.

But it wasn’t enough to keep alive Carolina’s postseason perfection at home — where a pig named Hamilton looks on from behind the corner boards.

Now they’re in an unenviable spot. Only four teams in NHL history have ever rallied to win a series they trailed 3-0, and none since Los Angeles in 2014 — though Carolina captain Justin Williams was on that Kings team that rallied to beat San Jose in the first round.

This one got away from them in the first 7½ minutes of the second, when the Bruins claimed control with their fourth line turning a turnover by Carolina’s Brock McGinn into a 1-0 lead at 1:21.

Sean Kuraly collected the puck and passed low to Joakim Nordstrom, with the former Hurricane then finding Wagner alone in front for a tap-in.

The Bruins entered with the NHL’s best postseason power-play unit — converting on a full third of their chances in the playoffs — and they were 1 of 5 with the man advantage against a Carolina penalty kill that began with a sub-50% success rate in this series.

But that one goal was a significant one.

With 19 seconds left on a high-sticking minor on Nino Niederreiter, Marchand put Boston up 2-0 when his shot from between the circles trickled past McElhinney.

It loomed large because the Hurricanes pulled within a goal when de Haan’s slap shot off a draw got through Rask’s pads for the defenseman’s first goal since Nov. 8.

The Bruins thought Torey Krug had an insurance goal with 15:45 left in the third, but the officials ruled Jake DeBrusk interfered with McElhinney — a decision that was confirmed after Boston’s challenge led to a review in Toronto.

That seemed like a significant development.

Rask made sure it ultimately wasn’t.

After stopping 20 shots in the first period alone — and becoming the first Boston goaltender since Tim Thomas in 2011 with that many in a postseason period — he remained difficult for the Hurricanes to figure out. Thwarting perhaps their best chance to tie it, Rask stuffed a slick power-play redirection by Jordan Staal with just under 13 minutes left.

This one was chippy throughout, with 14 penalties — 10 in the first period alone. That includes six by Boston and three by Williams, who also took his team’s only two penalties in a 6-2 loss in Game 2.

NOTES: Carolina scratched LW Jordan Martinook, who has been dealing with a nagging lower-body injury. … The Bruins improved to 5-1 this season against Carolina.
