BOSTON -- Boston Bruins general manager Peter Chiarelli kept his team together at the trading deadline, and then he told the players why.
"He said he believed in this team," said Bruins forward David Krejci, who scored his first NHL goal on Tuesday night to back Tim Thomas's second shutout of the season and help Boston beat the Ottawa Senators 4-0. "He said we have good chemistry on the ice, and that's why he didn't make any trades."
Ottawa acquired Blackhawks forward Martin Lapointe at the deadline, sending a sixth-round draft pick to Chicago. Lapointe was not yet with the Senators on Tuesday, when they could have used some more offense.
Ottawa, which leads the NHL with 210 goals, was shut out for the second consecutive game; it had not gone two games without scoring since November 2000. The Senators have won just twice in their last eight games to fall into second place in the East after leading the conference for much of the season.
"We're deep into frustration right now," coach John Paddock said. "We have to move the puck better, and we're not winning any battles."
Thomas, who was pulled from his last outing after giving up four goals on the first 12 shots on Thursday, made 22 saves to lead Boston to its fourth straight win.
"It was nice for me to come back with a strong game," Thomas said. "Important for me, but important for the team to keep the streak rolling."
Zdeno Chara scored twice, including an empty-netter, and Shawn Thornton also scored for the Bruins, who took the ice shortly after Chiarelli held on to his young players and said, "I have confidence in this team."
"This is a group of guys that has done a lot to try to grow as a team, and grow into their roles," Bruins coach Claude Julien said. "We've got a good mix of young and old. We've built some good chemistry."
Martin Gerber made 25 saves for the Senators, who also had a pre-game talk amid speculation that more changes are in store.
"We had a good meeting," Paddock said. "I don't know if there's any reason to shake it up."
The Senators defended their coach.
"We definitely believe in John for what he's done for us this year," forward Daniel Alfredsson said. "Right now we're not playing well as a team, and that makes everything look bad."
Boston scored first 5:24 into the game when Vladimir Sobotka dug the puck out of the corner and centered it to Thornton, who poked it between Gerber's legs. Krejci made it 2-0 with 2:37 left in the first period when he knocked in the rebound of Peter Schaefer's shot.
Chara's slap shot made it 3-0 with a power-play goal 2:15 into the second period.
Ottawa pulled the goalie with more than two minutes left and a power-play opportunity, but Chara added an empty-netter with 83 seconds left from inside the Bruins' zone. The goal gave him a new career-high with 44 points.
