Observations: Bruins 4, Blues 2

Brad Marchand scored two goals and Tim Thomas made 30 saves to help the Bruins snap a two-game losing streak with a 4-2 win over St. Louis. Milan Lucic and Chris Kelly also scored for the Bruins, who are 2-2-0 on their six-game road trip, which takes them to Buffalo on Friday and concludes in Ottawa on Saturday night.

Thomas holds the fort: As he has plenty of times this season, Tim Thomas put his team in a position to win. After allowing two goals in the first period, Thomas was stellar, turning away 14 shots in the second, eight in the third and finishing with 30 saves. Without Thomas in that second period, this could've been a very different game.

Bruins with three 20-goal scorers: With his two goals Wednesday night, Brad Marchand became the third Bruin to crack the 20-goal plateau and now has 21 lamp-lighters. Milan Lucic also scored his 21st goal of the season, and Tyler Seguin (assist Wednesday) has 20. Patrice Bergeron (assist Wednesday) and Nathan Horton are the next closest to 20 with 17 apiece.

Krejci and Chara find their games: While neither player registered a point in this game, both David Krejci and Zdeno Chara seemed to find their game again. Heading into the game, Krejci had only one point in his past 11 games -- not coincidentally, linemate Nathan Horton (concussion) had been out for all of them. Krejci recently acknowledged how much he missed Horton, and coach Claude Julien tried numerous line combinations to help the Czech forward find his game, including switching him to right wing at the end of the 2-0 loss to the Wild on Sunday and leaving him there on a line with Chris Kelly and Milan Lucic on Wednesday. Krejci played a much more involved game against St. Louis, finishing with a plus-2 and two shots in 20:03 of ice time. Meanwhile, Chara was a plus-3 with two shots in 23:27 after being a minus-9 in his past six games. Chara looked a lot more comfortable and wasn't trying to do too much out there.

Inconsistent play remains: While the overall effort was better, the Bruins still appear to be searching for that 60-minute effort. They took an early 2-0 lead 6:19 into the opening frame, but 58 ticks later the Blues cut the lead in half and just under six minutes later the game was tied. The Bruins did regain the lead with 40 ticks left in the first period but were outshot 14-4 in the middle frame.

Roster changes for the Bruins: The Bruins had some changes up front as coach Julien shuffled the forward lines, as he did toward the end of their 2-0 loss to the Wild. David Krejci was switched from center to right wing on a line with Milan Lucic on the left wing and Chris Kelly at center. Carter Camper made his Bruins debut, centering Jordan Caron and Benoit Pouliot. The defensive pairings remained the same. Here's what the lineup looked like to start the night:

Brad Marchand-Patrice Bergeron-Tyler Seguin

Milan Lucic-Chris Kelly-David Krejci

Daniel Paille-Gregory Campbell-Shawn Thornton

Jordan Caron-Carter Camper-Benoit Pouliot

Zdeno Chara-Johnny Boychuk

Dennis Seidenberg-Joe Corvo

Andrew Ference-Adam McQuaid

Tim Thomas

Tuukka Rask
