Boston Bruins at Buffalo Sabres

Pavel Zacha scores 38 seconds into OT to give the Bruins a 4-3 win over the Sabres

Casey Mittelstadt scored with six minutes remaining to tie the game, and Viktor Arvidsson also scored. Boston bounced back from a 4-2 loss to Toronto a night earlier, and moved into a tie in points with Montreal for third in the Atlantic Division standings — and three points ahead of eighth-place Ottawa.

Joonas Korpisalo finished with 22 saves.

Jason Zucker scored twice and Zach Benson also scored for Buffalo, which is 12-1-2 in its past 15. The Sabres still earned a point to tie Carolina atop the Eastern Conference and move within 10 points of clinching their first playoff berth in 15 years.

Ukko-Pekka Luukkonen made 27 saves.

The Bruins won after both teams squandered one-goal leads in the third period.

Pastrnak set up the decisive goal by gaining the Buffalo zone and attracting three defenders. He then slipped a pass to Zacha, who snapped a shot from the left circle that beat Luukkonen through the legs.

Pasternak extended his point streak to 11 games in which he has seven goals and 18 points. He also reached the 90-point plateau for the fifth time in his career.

The Sabres appeared to take control when Benson and Zucker scored 31 seconds apart to go up 3-2 with 14:06 left in regulation.

Mittelstadt, however, scored while appearing in his 500th career game, and against his former team.

Sabres captain Rasmus Dahlin’s fiancee Carolina Matovac is back in Buffalo and attended her first Sabres game since she nearly died after her heart failed while the couple vacationed in France last summer. She spent much of the past seven months in Sweden recuperating from heart transplant surgery.

Up next Bruins: Host Minnesota on Saturday.
