SAN JOSE — The Edmonton Oilers know the Sharks’ power play can’t dominate a game if it can’t get on the ice.

Marc-Andre Bergeron and Jarret Stoll each had a power-play goal and an assist in the first period, and the Oilers rode nearly two periods of penalty-free play to a 3-2 victory over San Jose on Wednesday night.

Mathieu Roy added his first career goal as Edmonton took a 3-0 lead in the first 111⁄2 minutes. Getting ahead was the easy part, particularly against a San Jose club prone to slow starts, but staying ahead required exemplary defensive play — or a whole lot of baffling officiating, according to Sharks coach Ron Wilson.

Either way, Dwayne Roloson made 32 saves as the Oilers held on in their first trip to the Shark Tank since last season’s Western Conference semifinals, won in six games by Edmonton after San Jose took a two-game lead into overtime of Game 3.

The Sharks had bombarded Dallas, Detroit and Columbus for 13 power-play goals in their previous three games, but didn’t get much of a chance to use that sharp man-advantage attack. Though the Sharks controlled much of the flow of play against Edmonton, the officials kept them on a parade to the penalty box with seven straight minor penalties in the first two periods.

“It’s hard to believe that you spend as much time as you do in the offensive zone that more penalties aren’t called on them,” Wilson said. “What are you going to do?”

Jonathan Cheechoo scored the Sharks’ 14th power play goal in four games early in the third period, but their three-game winning streak was snapped. Marcel Goc also scored, and Evgeni Nabokov made 13 saves.
