BOSTON - Marco Sturm's power-play goal late in the third period earned the Boston Bruins a 2-1 win over the Washington Capitals on Saturday afternoon.
The Capitals, who beat the Bruins 10-2 at home Monday, looked like they were in control for their fifth win in six games before becoming undisciplined with four key penalties in the closing minutes.
Donald Brashear got a double-minor for high-sticking and a minor for roughing on the same play. John Erskine had a minor for hooking 1:13 later and Tom Poti was sent off for slashing - all of them in the final 6:41.
Boston tied it on Zdeno Chara's power-play goal during a two-man advantage with 5:01 to play. Sturm's winner came when he converted David Krejci's goal-mouth pass with 2:16 remaining during another 5-on-3.
The Bruins halted a three-game losing streak.
The Capitals grabbed a 1-0 lead when Brooks Laich scored on a rebound after Alexander Ovechkin's consecutive shots 6:17 into the game. Ovechkin fired a wrist shot from the left circle and charged in for the rebound before Laich beat goaltender Alex Auld from the edge of the crease.
The Bruins tried to bully the Capitals early. Boston's Milan Lucic and Washington's Matt Bradley dropped the gloves five seconds into the game before the Bruins' Shawn Thornton took on Brashear nine seconds later.
Just over a minute later, Chara was called for interference when he knocked Ovechkin's stick out of his hands and into the net protecting the stands behind Boston's goal. A fan pulled the Washington star's stick through a hole at the bottom, but the NHL's scoring leader was able to get it back from an usher.
Ovechkin had three goals and two assists against the Bruins Monday.
Washington's Matt Cooke was given a five-minute major and game misconduct in the second period after appearing to stick his left leg out in a collision with Boston defenceman Bobby Allen, who injured his left knee on the play and was helped to the locker room. Allen returned later in the period.
Notes: Washington G Olaf Kolzig's next win will be his 300th. ... The Bruins' longest losing streak is six, coming in December.
