BOSTON - Matt Ellis scored a pair of goals to lead the Buffalo Sabres to a 4-2 win over Boston on Saturday, snapping the Bruins' 10-game winning streak and handing them their first home loss since late October.
Thomas Vanek had his team-leading 26th goal and Paul Gaustad also scored for the Sabres, who had lost four of their previous six - two in overtime.
Phil Kessel scored his team-leading 24th for Boston, and Shawn Thornton had the other goal.
It was just Boston's third home loss of the season, and the first since a 4-2 setback to Toronto on Oct. 23. The other was a 2-1 shootout loss against Pittsburgh in the home opener.
It was the Bruins' longest winning streak since 1973.
Ryan Miller made 29 saves for the Sabres and benefited from Boston's misplaced shots at three open nets.
Buffalo grabbed a 1-0 lead on Ellis' first goal 3:20 into the game. Henrik Tallinder's shot from the point trickled behind goalie Tim Thomas and Ellis poked the puck into the net.
Vanek's power-play goal gave the Sabres a 2-0 edge 1:48 later, when he redirected Derek Roy's shot by Thomas.
The Bruins cut it to 2-1 when Kessel one-timed Marc Savard's cross-ice pass for a power-play goal at 10:46.
Savard had a rough opening period when he failed to lift the puck over a sprawling Miller into an empty net and misfired from the right side of an open net with 6 1/2 minutes to play, dribbling the puck into the crease.
Ellis' second of the game - and just the fifth of his career - made it 3-1 at 3:04 of the second. The winger, recalled from Portland of the AHL on Dec. 8, swooped in for the rebound and lifted it over Thomas.
Boston cut it to one on Thornton's score at 9:51, but Gaustad's goal increased Buffalo's lead back to two just over three minutes later. Gaustad, positioned in front, redirected Andrej Sekera's shot and the puck caromed in from Boston defenceman Shane Hnidy's leg.
P.J. Axelsson, alone on the left wing, fired a shot into the side of the net with Miller out of position late in the second.
