The Penguins used a goal by Joe Vitale late in the first period to take the lead and they never looked back.
That goal turned out to be a decisive one as the Penguins recorded a 2-1 victory over the Boston Bruins. The Penguins have won nine games in a row and are in first place in the Eastern Conference.
The Penguins defeated the Bruins twice in five days, having won the first game by a 3-2 score March 12.
Sidney Crosby scored for the Penguins to open the scoring and Tyler Seguin of the Bruins matched that later in the first period.
David Krejci was hit by a shot from teammate Johnny Boychuk late in the third period and had to be helped off the ice. He did not return.
Pittsburgh defenseman Kris Letang also left the game with a lower-body injury in the first period and did not return.
