Rapid Reaction: Bruins 3, Rangers 1

What it means: Depth was the difference Saturday night, and the Bruins outmatched the Rangers in a 3-1 Game 5 victory at TD Garden that sent New York home for the summer. A rookie defenseman and an effective fourth line enabled the Bruins to secure a date with the Pittsburgh Penguins in the Eastern Conference finals, as the Rangers fell painfully short in a lopsided five-game series in which they were thoroughly outplayed. Gregory Campbell notched two goals, including an empty-netter in the last minute of play that made the home crowd erupt.

Difference-makers: The Bruins fourth line of Shawn Thornton, Daniel Paille and Campbell, a gritty trio that scored the deciding goal in Game 3, added another big one Saturday night. Capitalizing on a turnover from Rangers defenseman Roman Hamrlik, Paille made a cross-ice feed that bounced off Thornton to Campbell for the go-ahead goal at 13:41.

Kruuuuuuug: With his game-tying power-play marker in the second period, the fans at TD Garden were yelling "Kruuuuuuug!" in appreciation of rookie wonder Torey Krug. The 22-year-old defenseman scored his fourth goal in his first five playoff games, with a blistering one-timer that beat Henrik Lundqvist short side to knot the score at 1 at 3:48.

Power surge: No, that’s not a typo. For the second time in as many games, the Rangers notched a power-play goal with Dan Girardi’s slap shot that beat a screened Rask for a 1-0 Rangers lead at 10:39 of the first. The maligned unit has now tallied as many goals in the past two games as it managed on its previous 39 attempts during the playoffs.

Second scratch: For the second straight game, veteran Brad Richards was scratched. The struggling 33-year-old center sat out Thursday as the team faced elimination on Game 4, and, following the Rangers’ 4-3 overtime win, Tortorella stuck with the same lineup for Saturday.

Boost on back end: The Bruins returned Dennis Seidenberg to the lineup for the first time since the veteran defenseman was injured in the team’s first-round series against Toronto. Seidenberg replaced Dougie Hamilton, while rookie defensemen Matt Bartkowski and Krug remained in the lineup.

Rough stuff: Tough guys Thornton and Derek Dorsett dropped the gloves in the first period, a fight that kept going even after officials tried to separate the two players. Both received five for fighting and an extra two minutes for unsportsmanlike conduct. Dorsett racked up 11 PIM in total throughout the course of the game.
