BOSTON — Jake DeBrusk scored his second goal of the game to break a third-period tie, and the Boston Bruins came from behind to beat the Toronto Maple Leafs in Game 7 – again – winning 7-4 on Wednesday night to advance to the Eastern Conference semifinals.

Kasperi Kapanen put Toronto ahead 4-3 with a short-handed goal in the second, but Boston scored four times in the third period to pull away. Torey Krug tied it, DeBrusk gave Boston the lead with 14:35 to play, David Pastrnak added a goal with 8:21 left to help clinch it, and Brad Marchand lofted one into the empty net with 51 seconds left to set off a celebration in the stands.

Tuukka Rask stopped 20 of 24 shots for Boston, which will play the Tampa Bay Lightning in the second round starting at 3 p.m. Saturday.

Frederik Andersen had 29 saves for the Maple Leafs, who have not won a playoff series since 2004. They came close in the first round in 2013, when they rallied from a three-games-to-one deficit against Boston and took a 4-1 in Game 7, but the Bruins rallied to win it in overtime.

Danton Heinen scored his first NHL postseason goal, Patrice Bergeron had a goal and two assists and David Krejci had three assists for the Bruins.

Patrick Marleau scored twice for the Maple Leafs, who again won back-to-back games after falling behind 3-1 in the series. Game 6 came in Toronto on the night that a man drove a van onto a crowded sidewalk in the city, killing 10 people and injuring more than a dozen others.

The teams combined for five goals in the first period before Toronto scored twice in the second, taking a 4-3 lead when Kapanen beat Marchand to a loose puck and then held him off, skidding to a stop in front of Rask before poking the around his left skate.

In the third, the Bruins scored two 4-on-4 goals after matching penalties opened up the ice. Krug made it 4-4 on a slapper from the point just 1:10 in, and then DeBrusk scored the go-ahead goal when he outmuscled Jake Gardiner in the slot and put it between Andersen’s legs.

The Bruins forward slid into the boards behind the goal and didn’t even have a chance to get off his knees before he was mobbed by his teammates.

NOTES: Bruins Coach Bruce Cassidy, in his first full season on the Boston bench, was named a finalist for the Jack Adams Award as the NHL’s coach of the year. … Celtics Hall of Famer Tommy Heinsohn was the honorary fan banner captain, getting the crowd riled up before the game.
