MONTREAL -- David Desharnais and Erik Cole scored first-period goals and Carey Price made 32 saves to lead the Montreal Canadiens to a 2-1 win over the Ottawa Senators on Sunday.
Desharnais scored his third goal in two games on Montreal's first shot on Craig Anderson 2:13. Cole put the Canadiens ahead to stay with his second goal at 11:29.
Jakob Silfverberg gave Ottawa a short-lived 1-0 lead 1:38 into the game with a power-play goal on the Senators' second shot.
Anderson, who was named the NHL's first star for January, stopped 30 shots. He lost for a second straight game despite the fact that he has not allowed a goal in the second and third periods or overtime in any of his eight starts.
Ottawa, which lost, 1-0, at Carolina on Friday, has outscored its opponents, 20-5, after the first period this season.
The Senators had a potential tying goal waved off 1:26 into the third. Andre Benoit's shot from the point got past Price, but it was disallowed and Silfverberg was given a minor penalty for interfering with the Canadiens' goalie.
Silfverberg opened the scoring with his second goal on a breakaway. The 22-year-old Swedish rookie got behind three Montreal penalty killers at the Canadiens' blue line to take defenseman Patrick Wiercioch's long pass up the middle before going in alone to fire a shot past Price into the top right corner.
Desharnais, who scored his first two goals of the season in Saturday's 6-1 victory over Buffalo, drew Montreal even 35 seconds later.
Max Pacioretty set up Desharnais' goal in his return to the Canadiens' lineup, eight days after having an emergency appendectomy.
Cole put a backhand shot past Anderson at 11:29, only three seconds after Ottawa captain Daniel Alfredsson's tripping penalty expired.
Montreal's Rene Bourque drove a slap shot off the right post with just over eight minutes left in the third.
