ST. LOUIS -- The Boston Bruins knew if they were going to extend the season, they would need contributions from everyone in Game 6 of the Stanley Cup Final.
They got them, from veteran forward Brad Marchand to rookie forward Karson Kuhlman's first NHL playoff goal in a 5-1 win against the St. Louis Blues at Enterprise Center on Sunday.
The Bruins tied the series and forced a decisive Game 7 at TD Garden on Wednesday (8 p.m. ET; NBC, CBC, SN, TVAS).

Boston got the start it needed and opened the scoring on Marchand's 5-on-3 power-play goal 8:40 into the first period. The Bruins are 25-1 all-time when Marchand scores in the playoffs.
"We're fighting for our lives, obviously," Marchand said. "When you play desperate, normally you see everyone's best game and I think that's what we had tonight."
Defenseman Brandon Carlo scored what proved to be the game-winning goal, a shot that bounced past Blues goalie Jordan Binnington for a 2-0 lead at 2:31 of the third period.

Kuhlman, who hadn't played since Game 3 of the Eastern Conference Second Round against the Columbus Blue Jackets on April 30, scored after Blues defenseman Alex Pietrangelo turned the puck over near the blue line. His shot went over Binnington's right shoulder and under the crossbar to make it 3-0 at 10:15 of the third period.
Kuhlman replaced forward David Backes, who had gone six games without a point.
"One thing [Kuhlman] does, he brings some speed, he gets in on the forecheck with his foot speed," Bruins coach Bruce Cassidy said. "David is more of a physicality guy. [Kuhlman] can make some plays as well, and that shot, he's sneaky with his wrister. He's scored a couple times, that righty across the body.
"I don't want to give away state secrets here, but he does have that shot. Most righties want to go glove side. He's able to find the blocker side."
Kuhlman is the 21st different Bruins player to score at least one goal this postseason, which ties the NHL playoff record for most unique goal scorers by one team (1987 Philadelphia Flyers).
"It's been a little bit," said Kuhlman, who hadn't scored since April 2 against Columbus. "But at the same time, you come into every game just trying to work hard, and [I] was fortunate to see that one go in."

Bruins forward David Pastrnak ended a four-game goal drought at 14:06 of the third period to make it 4-1, and defenseman Zdeno Chara scored an empty-net goal with 2:19 remaining for the 5-1 final.
Boston knows it will need a similar effort in Game 7 to win the Cup.
"I think it was nice for certain players to break through and get some points and some goals and to play their games to their abilities," defenseman Charlie McAvoy said. "We rely so much on group efforts, so it has to be our whole team.
"That being said, there's no carryover. As all of you know, it's a new game, and everyone's going to get better from this and watch it and learn tendencies. So when the puck drops on Wednesday, it's going to be a fresh start."
