Tomas Vokoun made 30 saves for his third shutout of the season and Alexander Semin scored on the second of Washington's two penalty shots in the Capitals' 3-0 win over the Montreal Canadiens on Saturday.
Vokoun recorded his 47th NHL shutout, his first in 21 games against Montreal. He debuted with the Canadiens in 1996-97.
Peter Budaj stopped 20 shots for the Canadiens, who lost their third in a row.
Wideman scored his 10th goal on a floater from the point after Brooks Laick won a faceoff in the Canadiens' zone 8:10 into the game. Hendricks made it a two-goal lead 6:11 into the third.
Semin fired a slap shot past Budaj on his penalty shot 11:57 into the third after he was hooked by Tomas Kaberle on a breakaway.
Budaj stopped Troy Brouwer on Washington's first penalty shot 9:16 into the second. Brouwer was awarded the penalty shot by referee Rob Martell after Budaj threw his stick at the puck.
Montreal's Scott Gomez failed to score a goal for his 51st straight game, ensuring that he will go a full calendar year between goals. The veteran center, in the fifth year of a seven-year, $51.5-million contract he signed with the New York Rangers, last scored on Feb. 5, 2011.
