BOSTON – Nazem Kadri scored the only shootout goal to help the Toronto Maple Leafs beat the Boston Bruins 4-3 on Thursday night.

With the point for reaching overtime, the Bruins clinched a tie for the Northeast Division title. The next Boston win or loss by Montreal will give the Bruins the division title.

Toronto is 10th in the Eastern Conference, five points behind seventh-place Buffalo and the New York Rangers for one of the eight playoff spots.

Joffrey Lupul scored twice for Toronto, Luke Scheen added a goal and former Bruins forward Phil Kessel had a pair of assists. Brad Marchand, David Krejci and Andrew Ference scored for Boston.

Bruins goalie Tim Thomas, who made 28 saves, made a right-pad save on Mikhail Grabovski’s penalty shot 43 seconds into overtime, but Kadri beat him with a backhand shot over the left shoulder in the shootout.

Tyler Seguin, Michael Ryder and Rich Peverley each failed in the shootout for the Bruins. James Reimer made a glove stop on Peverley to end it.

Grabovski was awarded the penalty shot when he was hooked by Steven Kampfer after beating Zdeno Chara for a clean breakaway. Thomas also made a sliding right-pad save on that scoring bid.

Boston had a power play for the final 1:05 of overtime after Lupul was called for slashing, but Reimer made a couple of good stops on long-range shots. He finished with 35 saves.

Lupul’s second goal of the game tied it at 3 with just over 12 minutes left in the third period. He slipped a wrister past Thomas from the right circle.
