Ben Smith scored just hours after being acquired by San Jose in a deadline deal and the Sharks shut out Montreal for the third straight meeting in a 4-0 win over the Canadiens on Monday night.
Joe Pavelski, Matt Irwin and Patrick Marleau also scored for the Sharks, who snapped an eight-game home losing streak by beating the top team in the Eastern Conference.
Alex Stalock made 20 saves for his fourth career shutout and first win since Jan. 6 at Minnesota. That performance followed Antti Niemi's two shutouts against the Canadiens last year, giving San Jose three straight shutouts against a single opponent for the second time in team history.
The Canadiens got off to a bad start on their four-game West Coast trip as they were outplayed from the start against San Jose. Carey Price made 33 saves and snapped his franchise record 10-game road winning streak.
