Power-play goals by Brad Marchand and Torey Krug in the first period sparked the Boston Bruins to a 4-2 road win against the Toronto Maple Leafs on Sunday to force a Game 7 in their opening-round Stanley Cup playoff series.

Tuukka Rask made 22 saves for Boston.

Needing a win to force a deciding game at home Tuesday in Boston, the Bruins regrouped after falling behind early, took a lead and then held on to tie the best-of-seven series at 3-3.

The Bruins have won their last two series with Toronto in seven games, including a first-round set last spring. The Maple Leafs last beat Boston in a playoff series in 1959.

With their chance to win a playoff round for the first time since 2004, the Maple Leafs had the start they wanted when Morgan Rielly opened the scoring by blasting home a point shot at 9:42 of the first period.

However, the Bruins have used their potent power play to great results all series, and it earned them the lead.

Marchand tied the game at 11:23 of the first period when he grabbed the puck off the face-off and banked a shot off the leg of Toronto defenseman Ron Hainsey. Then, Krug made it 2-1 with three minutes left in the opening period by one-timing a loose puck during a scramble.

Jake DuBrusk scored his first goal of the playoffs when he and David Krejci used a couple of give-and-go passes and criss-crossed during a two-on-two rush 7:57 into the second period to extend Boston’s lead to 3-1.

Toronto gained new life when Auston Matthews rifled a shot at 4:15 of the third period to make it a one-goal game, but Marchand capped a three-point game with an empty net goal at 18:06.

David Pastrnak collected two assists for the Bruins. Toronto goalie Frederik Andersen stopped 37 shots in the loss.
