Boychuk/By S. Bradley

BOSTON — Defending Stanley Cup champions aren’t supposed to have such low expectations.

But when you’ve failed to win two games in a row 10 games, it’s the little things that matter most.

The Bruins finally broke through and won back-to-back contests, as Thursday night they followed up Tuesday’s win over Toronto with a 3-1 win over Buffalo at the TD Garden.

Johnny Boychuk scored the game-winning goal with 7:04 remaining in regulation. David Krejci added the insurance goals. Gregory Campbell had tied the score with 1:51 left in the second period.

Tim Thomas faced just 20 shots and stopped 19 of them. Meanwhile, Jordan Caron moved up to the line with Patrice Bergeron and Brad Marchand, and he helped set up Boychuk’s goal. Brian Rolston dropped down and played with Chris Kelly and Benoit Pouliot.

The Bruins maintained a three-point lead on Ottawa for the Northeast Division lead.
