BOSTON — Bruins head coach Claude Julien is always looking for the team’s power play to at least generate momentum if not goals.

Today all the club got from its man-advantage was indifference.

Boston’s inability to capitalize on four power-play opportunities cost the Bruins dearly in a 2-0 loss to San Jose at TD Garden.

The Sharks, on the other hand scored their game-winning goal on the power play just 7:22 into the game on a backhand shot by super-rookie Logan Couture after a David Krejci giveaway at the Sharks blue line.

Devin Setoguchi added an empty-net goal.

The Bruins’ power play is 0-for-12 over the last five games.

“Tonight is certainly not one that we would say our power play was good,” said Julien. “I think the other night against Dallas, even though we didn’t score, our power play was good and we moved the puck well and we had some chances. We didn’t score, OK, and then at the end of the night you say you’ve got to score some goals. But we had some good chances. So we really felt our power play had taken a stride in the right direction.

“Tonight was a completely different case. We weren’t good enough in that area, and again this is our best players having to be at their best.”

Here’s a glance at the rest of the box score:

•The Sharks blocked 25 shots, led by seven from Douglas Murray and five from Ben Eager.

•Krejci and Zdeno Chara led the Bruins with four shots on net apiece.

•Tim Thomas was the hard-luck loser with 17 saves on 18 shots.
