The Bruins won their second straight game for only the second time this month, and it comes on the heels of a 2-3 road trip. Boston is at home for five of its next seven games.

Mann scored his first goal of the game and second of the season on a power play at 12:01 of the second period. The goal, on a rebound of a Randy Robitaille shot from the right side, gave the Bruins a 4-1 lead. His second goal of the night came at 12:03 of the third period when he flicked home a rebound of his own shot.

Despite coming into the game with a 6-2-2 record, a 1.25 goals against average and a .940 save percentage on the road this season, Senators goalie Ron Tugnutt (17-7-5) was chased from the net after the first period when the Bruins scored three goals on 14 shots, taking a 3-1 lead.

"We didn't play well from the start. They wanted to win more than us. They went right after it," said Senators coach Jacques Martin.

The Senators are 2-1-1 in their last four road games and 2-2 against Boston this season.

Tim Taylor gave Boston a 1-0 lead at 1:31 of the opening period when he curled the puck into the right corner from the crease for his fourth goal of the season.

Shawn McEachern tied the game at 10:01 of the period with his 27th goal on a backhander from the left of the crease. He is tied with Alexei Yashin for the team lead for most goals.

"We've been in the same situation [fighting to make the playoffs] the past two seasons that Boston is in right now," said McEachern. "We knew before the game they were going to take it to us. We made too many mistakes defensively and they capitalized on that."

Jason Allison's one-timer from the slot at 12:29 of the opening period, his 16th, gave the Bruins a 2-1 lead.
