ST. LOUIS (AP) — Facing elimination in a hostile environment, Brad Marchand and Tuukka Rask stepped up for the Boston Bruins once again.

The Stanley Cup Final is heading to Game 7 because two of Boston’s biggest stars love the biggest moments.

Rask made 28 saves, Marchand had a goal and an assist, and the Bruins beat the St. Louis Blues 5-1 on Sunday night to even the bruising, physical final at three games apiece.

David Pastrnak had a goal and an assist as Boston became the 17th team to go on the road and force a Game 7 in the Stanley Cup. The Bruins also were the last franchise to accomplish the feat, coming all the way back to win the championship against Vancouver in 2011.

Rask was a reserve goaltender on that team eight years ago, while Marchand was a key performer. They will go for another championship Wednesday night in Boston after losing to Chicago in the 2013 final.

Ryan O’Reilly scored in the third period for St. Louis, which is looking for the franchise’s first Stanley Cup title. Rookie Jordan Binnington finished with 27 stops.

Backed by an electric Enterprise Center crowd that included actors Jon Hamm and Jenna Fischer and Cardinals catcher Yadier Molina, wearing a No. 49 Blues jersey in honor of suspended forward Ivan Barbashev, St. Louis looked a step off for most of the game. Prime scoring opportunities were derailed by misplaced passes or ever-so-slight timing issues.

Of course, the unflappable Rask can have that effect on a team. And whenever the Blues threatened, the 6-foot-3 Finnish star was there.

Rask was at his best while Boston killed off four power plays, dropping St. Louis to 1 for 18 with the man advantage for the series. He smothered a big Colton Parayko slap shot with Zdeno Chara in the box near the end of the first period, and made a fancy glove stop on an even-strength try for Brayden Schenn 7:42 in the second.

He got some help after Marchand was whistled for tripping Alex Pietrangelo midway through the second. With the Blues applying heavy pressure in search of the tying goal, Pietrangelo had a backhand go off the left post and Rask’s back before Bruins defenseman Charlie McAvoy knocked the puck out of the way out of midair.

While St. Louis came up empty on the power play, Boston used a 5-on-3 advantage to jump in front in the first. With Schenn and O’Reilly in the box, Marchand beat Binnington with a sharp-angled shot from the right circle at 8:40.

It was Marchand’s first goal since he got an empty-netter in Boston’s 4-2 victory in Game 1. The Bruins improved to 25-1 when the pesky veteran scores in the postseason.
