BOSTON -- Dany Heatley has made the most of his fresh start.
"When I saw him in training camp, he didn't look like a special player," Senators goalie Dominik Hasek said, laughing. "He is a great stickhandler, knows where to be on the ice and where to shoot the puck."
Heatley has scored in all 14 games for Ottawa this season, and has 13 goals and 26 points.
"With the year off, I think most guys were excited to get going, but coming to Ottawa, a new place, made me even more excited," said Heatley, who had a turbulent 2003-04 season after he was involved in a fatal car accident at the start of training camp and played only 31 games after battling through injuries.
The Senators won their fourth straight and improved to 9-0 against Northeast Division teams.
"We go 4 to 5 minutes in a row killing penalties and then you face that line," Bruins goalie Andrew Raycroft said. "It makes it real tough, almost impossible.
After Smolinski put Ottawa ahead 2-1, Wade Redden passed to a streaking Havlat, who hit the post. Schaefer knocked the rebound for a short-handed goal.
The Bruins lost in regulation for the first time since Oct. 20 against Buffalo. Boston had recorded a point in nine straight games.
"All three are dynamic players and great 1-on-1 players," Bruins coach Mike Sullivan said. "No matter who plays against them on any given night, they have their hands full."
Havlat scored his seventh goal in the second-period run for Ottawa, who have had eight different players score in two victories against the Bruins this season.
Ottawa went 0-for-7 on the power play and Boston has now killed off 48 of its last 52 short-handed situations.
Free-agent acquisition Alexei Zhamnov played his first game for the Bruins.
The Senators were playing their first game in five days and looked rusty in the first period, getting outshot by Boston 17-5.
