ST. LOUIS — Facing elimination in a quite 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 deciding game is Wednesday night in Boston.
