Alexander Semin had a goal and set up Jay Beagle's go-ahead score Saturday, lifting the Washington Capitals to a 4-3 win over the Boston Bruins.
It was the second straight win for the Capitals after a three-game losing streak (0-2-1).
Washington moved two points ahead of Winnipeg and is now in sole possession of eighth place in the Eastern Conference. Washington also trails Florida by one point in the Southeast Division.
Brooks Laich and Matt Hendricks also scored, and Tomas Vokoun stopped 30 shots for the Capitals.
Brad Marchand, Milan Lucic and Johnny Boychuk scored for Boston, which failed to extend its winning streak to three games for the first time since late December.
Tim Thomas, playing in his eighth consecutive game, made 26 saves for the Bruins.
Washington improved to 20-0-0 when it leads after two periods.
Boston tied the game on Marchand's goal 4:58 into the second before the Capitals scored twice over the final 8:38 to take 4-2 edge into the third.
