DENVER -- Even though Ilya Bryzgalov wasn't impeccable, the Anaheim Mighty Ducks remained perfect thanks to Joffrey Lupul's four goals Tuesday night.

Lupul's three goals in regulation and one in overtime gave the Ducks a 4-3 win over the Colorado Avalanche and a 3-0 lead in their Western Conference playoff series.

Bryzgalov's shutout streak ended at three games, but the Ducks still moved to within one win from advancing to the conference finals.

The Ducks can complete the sweep Thursday night at the Pepsi Center. The Avalanche will try to join the 1975 New York Islanders and the 1942 Toronto Maple Leafs as the only teams to win series after losing the first three games.

Colorado had won its last six playoff overtime games.

After both teams killed a power play in the extra period, Dustin Penner stole the puck from Patrice Brisebois in the Colorado zone and fed Lupul, who added to his first career hat trick with a shot from between the circles that beat Avalanche goaltender Jose Theodore at 16:30 of overtime.

The Avalanche took a 2-1 lead on Jim Dowd's short-handed goal early in the third period, but Colorado was lax on defense and allowed Lupul to score his second and third goals less than 2 minutes apart.

Avs defenseman Rob Blake scored to tie the game.
