Nathan Horton's goal with only 7:33 left in the third period lifted the Boston Bruins to a 1-0 victory over the Tampa Bay Lightning in Game 7 of the Eastern Conference final on Friday night.

Dwayne Roloson improved to 7-0 in post-season elimination games and Martin St. Louis scored two goals and an assist as the Tampa Bay Lightning forced a Game 7 on Friday by defeating the Boston Bruins 5-4 at the St. Pete Times Forum on Wednesday.

Boston’s 19-year-old rookie — a healthy scratch in the playoffs until debuting and scoring in Saturday’s Game 1 loss — tallied two goals and two assists to lead the Boston Bruins past the Tampa Bay Lightning 6-5 in Game 2 of the Eastern Conference finals on Tuesday night.

For the first time in playoff history, the Boston Bruins and Tampa Bay Lightning will meet with a berth in the Stanley Cup final up for grabs.

David Krejci, Nathan Horton and Rich Peverley gave the Boston Bruins a three-goal lead and the team held on for a 4-2 win over the Montreal Canadiens on Monday night at the Bell Centre.

It’s NHL playoff time and two Original Six teams will add another chapter to a storied history between bitter rivals.
