The Boston Bruins defeated the Pittsburgh Penguins, 5-2, behind three-point nights by Marc Savard and Dennis Wideman in the first half of a home-and-home series tonight at Mellon Arena. You can read the game recap at Yahoo.

Here are my notes and thoughts:

•The Bruins’ power play had been 0 for its last 14 before Zdeno Chara lit the lamp on the man-advantage with 4:46 elapsed in the second period.

MK: The power play finished the night 2-for-8. That’s a huge improvement for one of the few areas the Bruins had struggled in of late. If the power play is really back into form, this winning streak might never end. Obviously, the power play needed some time to adjust in the aftermath of Patrice Bergeron’s departure from the line-up. Chara and  Wideman, in particular, seemed to be having a tough time with chemistry at the points before tonight.

•Bruins goaltender Tim Thomas has now won seven straight starts.

MK: This goaltender rotation thing is just too easy for head coach Claude Julien right now — just flip a coin and watch the crucial saves get made with ease.

Martin St. Pierre scored a shorthanded goal — the club’s fourth of the year.

MK: Last season, the Bruins scored nine shorties, so they’re right on pace in that department. As for St. Pierre, the Bruins have to be wondering if removing him in favor of a soon-to-be-healthy Petteri Nokelainen will be the right move. It seems that St. Pierre, who hadn’t scored an NHL goal since Feb. 14, 2007 (his only other score in the big leagues), gives the Bruins everything — plus an offensive touch — that Nokelainen gives them. This will be an interesting development to watch in the week ahead.
