EDMONTON, Alberta (AP) -- The Edmonton Oilers rebounded from a particularly rough road trip with another excellent performance at home.

Ryan Smyth had a goal and an assist and Dwayne Roloson stopped 19 shots as the Edmonton Oilers beat the Washington Capitals 4-0 on Saturday night.

Fernando Pisani, Joffrey Lupul and Marty Reasoner also scored for the Oilers who were coming off a pair of 6-2 losses on a two-game road trip to Anaheim and Phoenix.

The Oilers (7-4) improved to 6-0 at home.

"It's a little bit of a change from last year," Roloson said. "Last year when I got here we were a great road team and at home we weren't as great. But we'll be fine on the road. We have a long trip coming up in a couple weeks and I'm sure we can turn it around then."

Oilers head coach Craig MacTavish is pleased with his team's play at their rink, but says they need to improve on the road.

"We haven't had a lot of success on the road this year," he said. "We've only won one game out of five, which is certainly not the level we want to be at."

The Capitals, who lost 3-2 in a shootout on Friday night in Vancouver, felt better about their play in this game despite the loss.

"That is likely our best game of the three-game trip so far," Capitals coach Glen Hanlon said. "To me, it wasn't really a four-goal game. I almost have a better feeling tonight than I had after taking a point in Vancouver. It's a long process to get where we want to go this year but I think we looked farther ahead tonight than we did the night before."

The Capitals dropped to 3-3-4, though MacTavish agreed that Washington played better than the score indicated.

"They played us hard," he said. "They are going to win some games."

Midway through the first period, Smyth blasted a slap shot to the top corner that blew by goalie Brent Johnson. The power-play goal was Smyth's sixth of the season.

After a scoreless second period, the Oilers took a 2-0 lead five minutes into the third when defenseman Marc-Andre Bergeron drifted a knuckleball at the Capitals net and Pisani tapped it in.

Edmonton put the game away with just under four minutes left when Johnson allowed a big rebound on a shot by Petr Sykora and Lupul capitalized for a power-play goal.

Reasoner added an empty-net goal.

It was the first time Alexander Ovechkin, last season's rookie of the year, played against Edmonton.
