Selanne opened the scoring midway through the initial period when he one-timed a feed through the crease from Saku Koivu for his first goal of the season.
The Finnish great made it 2-0 5 minutes later when he batted in the rebound of Koivu's shot off San Jose goalie Antti Niemi, who was making his season debut after missing the Sharks' first three games.
Niemi stopped 19-of-21 shots.
