BOSTON — Brad Marchand had two of his three goals and set up another in Boston’s five-goal second period, and the Boston Bruins rebounded from a lackluster effort with a 7-5 victory over the Pittsburgh Penguins on Saturday afternoon.

Patrice Bergeron moved into a tie for fourth on the club’s all-time scoring list. David Pastrnak scored twice, David Krejci and Bergeron each had a goal for Boston. Bergeron has 899 career points to equal Rick Middleton (898).

Playing for the first time after coach Bruce Cassidy called out some of his top veterans two days ago, saying he was “disappointed” in their play, the Bruins’ core group struck in big numbers in the second period.
