ANAHEIM, Calif. -- Dwayne Roloson made 33 saves, Fernando Pisani and Chris Pronger scored key goals, and the Edmonton Oilers beat the Anaheim Mighty Ducks 3-1 Sunday night to take a commanding lead in the Western Conference finals.

The Oilers own a 2-0 advantage in the best-of-seven series and a six-game playoff winning streak. They will take both back home, where they've defeated the Ducks 12 in a row, dating to 1999.

Game 3 is in Edmonton on Tuesday and Game 4 there on Thursday.

Roloson, the 36-year-old goalie who was with Minnesota when the Wild lost to Anaheim in the 2003 playoffs, kept up his outstanding play for the Oilers, who acquired him in a March trade.

Anaheim kept steady pressure on Roloson, but he blocked, gloved, batted and kicked away almost everything the Ducks could throw at him. The only puck that got past him was Jeff Friesen's point-blank shot in traffic in the second period.

Pisani scored the go-ahead goal at 17:09 of the second period. Michael Peca added an empty-net goal in the waning seconds in a game very similar to the Oilers' 3-1 victory in the series opener.

A perfect pass from Sergei Samsonov set up Pisani's 20-footer down the slot. Skating in a crowd near the crease, Samsonov spotted Pisani and backhanded the puck to him. Pisani's one-timer sailed past goalie Ilya Bryzgalov and into the net.
