After being outshot 16-11 in the first period, New Jersey took a 1-0 lead at 2:16 of the second on Hischier's short-handed goal.
Hischier scored from the left face-off circle on a breakaway with a shot that bounced in off the far post.
Boqvist extended it to 2-0 from the left circle at 7:43 after a wild sequence that saw the puck nearly cross the goal line, Bobrovsky lose his stick after a shot hit the post, and Barkov and Staal get injured. Both remained in the game.
"We had the perfect situation going into the third," Devils defenseman Jonas Siegenthaler said. "We just gave it away. It shouldn't happen. Everybody knows it in here."
