OTTAWA -- The Ottawa Senators' top line keeps adding to its impressive scoring totals.
Spezza and Alfredsson both have 39 points, tying the New York Rangers' Jaromir Jagr and Philadelphia's Peter Forsberg for the NHL scoring lead. Heatley moved up to fifth overall with 37 points.
"We read off each other well," Spezza said. "It may look like we plan things but a lot of times it's criss-crossing and finding the holes. Nobody's selfish with the puck and I think that's what makes us a good line. We move the puck well and nobody cares who scores the goals."
Heatley needed only 34 seconds to extend his points streak to 21 games, picking up an assist on Spezza's goal on the opening shift. Alfredsson also got an assist on the play, with Spezza scoring off Heatley's rebound.
"I know it's there, but I'm not putting too much emphasis on it," Heatley said of the streak. "I just want to go out and play well, move the puck with those two and things will care of themselves."
The Senators, 18-3-0 overall, have won five straight and 10 of 11. Eastern Conference-leading Ottawa opened the season with six straight wins from Oct. 5-21.
"They really can't do too much wrong," said Bruins goalie Andrew Raycroft, who made 36 saves as the Senators outshot Boston 40-24, including a 16-5 margin in the first.
Boston (8-12-5) lost for the second straight night after ending a season-high six-game losing streak Wednesday night with a 5-1 win in Toronto.
"We make it hard on ourselves in certain situations," Bruins coach Mike Sullivan said. "We've got opportunities to advance the puck and move the puck, simple options, short options, and we're looking for the better play and it's cost us. You combine that with some avoidable penalties against a team like this, that has a potent power play, and it's tough to win."
Ottawa went 2-for-5 with the man advantage. Boston was 0-for-7.
Veteran defenseman Brian Leetch returned to the Bruins' lineup after missing 10 games because of a knee injury.
"I had high expectations but the game seemed pretty quick to me out there after being off for a month," Leetch said. "I got caught looking a few times on some of their criss-crosses and stuff, but overall the knee held up pretty good."
Spezza's 10th goal, a power-play score 9 seconds into the second period, put the Senators up 2-1. Heatley, who made a skate save to prevent a Boston goal midway through the third, made it 3-1 when he scored his 17th goal on another power play at 15:41.
Alfredsson added his team-leading 19th goal 6:21 into the third, teaming up with Heatley and Spezza once again.
Heatley even displayed some goaltending skill moments later, backing up Dominik Hasek who was caught out of the nets after making a sprawling save on Eric Nickulas' shot. Standing at the left post, Heatley had Tom Fitzgerald's follow up shot deflect off his skate and along the goal line.
Heatley has 17 goals and 20 assists and is the only NHL player to register a point in every one of his team's games this season.
Spezza, who has scored a goal in each of his last four games, extended both his assist and point streaks to six games.
The Corel Centre crowd observed a moment of silence prior to the game in memory of Ottawa forward Chris Neil's mother Bonnie. She was killed in a car accident Tuesday.
- Bruins captain Joe Thornton assisted on Boynton's goal to extend his point streak to five games.
- Alexandre Daigle holds the Senators' record for fastest goal from the start of a period. Daigle, now with Minnesota, scored 7 seconds into the second period of Ottawa's 3-3 road tie against the New York Islanders on Jan. 22, 1995.
- Neil has missed three games since learning of his mother's death while he was with the team in Raleigh, N.C. Bonnie Neil's funeral was held Saturday.
- Senators rookie Andrej Meszaros was originally credited with Spezza's second goal. He lost what would have been his first NHL goal when off-ice officials reviewed the play following the game and determined Spezza had tipped the defenseman's point shot. "I'm not disappointed," Meszaros said. "The most important thing is we won the game."
