BOSTON — If ever there was a night to just chill out, the Bruins had one with a desperate Chicago team in town tonight one game after Boston wrapped up its playoff berth.

But the Bruins decided to take things to the other extreme.

After outshooting the Blackhawks, 12-5 in the first period, the Bruins barely relinquished the momentum the rest of the game at TD Garden en route to a 3-0 shutout highlighted by Tim Thomas’ 32 saves.

“I think it was important for us to follow what we said,” said head coach Claude Julien, who preached to his team since Sunday that it can’t let its foot off the gas yet. “We had to come out strong, especially against a team that’s desperate, is a pretty good team, the Stanley Cup champions. We needed to be ready. This is one game, we’ve got more to come and we’ve just got to keep taking that approach.”

Thomas now has nine shutouts on the season and his league-leading totals in goals-against average and save percentage now sit at 1.96  and .940, respectively.

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

•Zdeno Chara, Johnny Boychuk and Nathan Horton scored the goals. Chara now has 3-8-11 totals in his last 10 games. Horton now has four goals in his last four games.

•Chara was the only plus-3 player on the night. Selke Trophy candidate Jonathan Toews was minus-3 for Chicago.

•The Bruins did not get a power-play attempt all night.
