Dumoulin won it with a wrist shot from the inside edge of the left face-off circle off a drop pass by Dawson Mercer.

Timo Meier had a goal and two assists, and Mercer had a goal and an assist for the Devils (42-32-7), who already had secured the No. 3 seed in the Metropolitan Division for the Stanley Cup Playoffs and will face the Carolina Hurricanes, the No. 2 seed, in the Eastern Conference First Round. Nico Hischier and Luke Hughes each had two assists, and Jake Allen made 20 saves.

The Devils will play their regular-season finale against the Detroit Red Wings at home on Wednesday.

David Pastrnak had a goal and an assist, John Farinacci scored in his NHL debut, and Nikita Zadorov had two assists for the Bruins (33-39-10) in their season finale. Jeremy Swayman made 21 saves.

Boston failed to qualify for the playoffs for the first time since the 2015-16 season.

Meier gave the Devils a 1-0 lead at 7:25 of the first period when his quick shot from the right circle beat Swayman to the far post.

Morgan Geekie tied it 1-1 at 8:43. Pastrnak made a cross-ice pass to Geekie, who was waiting at the top of the left circle for a one-timer that beat Allen to the short side.

The Bruins took a 2-1 lead on Pastrnak’s 43rd of the season at 29 seconds of the second period. After a give-and-go with Elias Lindholm at the offensive blue line, Pastrnak split two defenders and scored with a backhand.

Stefan Noesen tied it 2-2 on the power play at 4:07, shoveling the puck in from the crease after Swayman couldn’t cover it.

Simon Nemec gave the Devils a 3-2 lead 30 seconds later. His wrist shot from the high slot looked like it was going to sail over the net when Swayman attempted to play it with his blocker and it ricocheted into the net.

Mercer increased the lead to 4-2 when he scored on the power play at 13:37, but Farinacci cut it to 4-3 at 16:53 by scoring on a rebound from the right circle.

Marat Khusnutdinov then tied it 4-4 at 5:08 of the third period. After Fabian Lysell won a race to the puck in the offensive zone, he fed Khusnutdinov for a one-timer from the slot.
