The Bruins’ youth movement continues to pay off on the ice.

Just over two weeks after 19-year-old center Matthew Poitras buried his first two NHL goals in the same game, two more Bruins rookies recorded their first career numbers in the same period on Monday night against Dallas.

Boston built a 2-0 lead in the first 20 minutes thanks to a pair of milestone goals from Johnny Beecher and Mason Lohrei, with both skaters lighting the lamp less than four minutes apart at the American Airlines Center.

Beecher, playing in his 12th NHL game on Monday, opened the scoring for Boston at 10:21 of the opening frame.

After grabbing the puck off the glass, the 22-year-old pivot cut hard toward the net and fired a sacrifice past Stars goalie Jake Oettinger for his first goal.

“I kind of just wanted to go from low to high there,” Beecher said during NESN’s break report. “And then their winger kind of cut it off. So I thought I’d just try to attack the middle as best I could and then just try to break one off quickly before they got a stick on it. So it worked. … That was perhaps one of the better goals I have ever scored.”

Not to be outdone, Lohrei joined Beecher on the scoresheet at 14:09 of the first period.

Danton Heinen sparked the scoring streak, hitting the rookie defenseman with a sharp feed after Lohrei skated from the offensive blue line to the high slot. The shot-ready skater didn’t hesitate, uncorking a blistering wrist shot that beat Oettinger and doubled Boston’s lead.

Lohrei, called up to Boston last week amid a series of injuries and suspensions among the Bruins’ D-corps, dominated in his NHL debut against the Maple Leafs last Thursday. He recorded an assist and logged 21:28 of ice time in Boston’s shootout win.
