Ramus Asplund, Brandon Montour and Rasmus Ristolainen also scored for the Sabres, who recently snapped an 18-game winless streak. Linus Ullmark made 27 saves to beat the Devils for the fourth time this season.
Damon Severson, Jesper Bratt and Pavel Zacha scored for New Jersey, cual es 1-4-2 in its last seven games. Scott Wedgewood made 13 saves in his first start in five games.
Dahlin tied the game 3-all at 15:19 of the second period with a shot from low in the left circle. It was only the third goal of the season for the No. 1 overall pick in the 2018 draft.
Mittelstadt’s game winner came with 9:40 left in regulation with the Sabres on their second power play of the period. Dahlin prevented Travis Zajac from clearing the puck, skated to the right circle and found Mittelstadt for a redirection into an open net.
Ristolainen iced the game with an empty-net goal as the Sabres won on the road for the first time since a 4-1 victory at New Jersey on Feb. 23. The road skid was the NHL’s longest since the Los Angeles Kings went 0-10-1 from Oct. 24 to Dec. 7, 2019.
The game between the bottom two teams in the East Division was entertaining and was tied 3-all after two periods. It also featured the NHL debut of Tyce Thompson, the brother of Sabres forward Tage Thompson.
Tyce Thompson helped the Devils take an early with lead, putting a shot on goal that Ullmark couldn’t handle. Severson knocked in the rebound.
Taking advantage of a turnover and nice pass by Mittelstadt, Asplund tied the game for Buffalo midway through the first period.
Montour scored his fourth goal in five games with a rebound in the final minute of the opening period, but Bratt tied the game in the final second with a power-play goal.
Zacha knocked in his own rebound while basically sitting on the ice to give New Jersey a 3-2 Plomo. Dahlin answered just over four minutes later.
