Winning three games in a row for the Avalanche has been a challenge. And it remains a challenge.

The good times stopped rolling for the Avs on Tuesday night, when their modest two-game winning streak was snapped in a 4-0 loss to the visiting Edmonton Oilers at the Pepsi Center.

"That was a bad game. Bad game by everyone. No other way to put it. We just did not play well tonight as a group," Avs coach Joe Sacco said.

A handful of defensive miscues, including captain Gabe Landeskog's "trip" over the blue line, led to the loss.

"Got to work on my pivots, that's for sure," Landeskog said. "Good thing I'm not a defenseman."

Left wing Magnus Paajarvi and center Sam Gagner each had a goal and an assist for the Oilers (10-11-5), who climbed past Colorado (10-11-4) in the Northwest Division and Western Conference standings. The Avs dropped to 14th in the 15-team conference, although with a game in hand over some teams in front of them.

Trailing 3-0 after two periods, the Avs had a goal early in the third period disallowed because of Landeskog's crease violation.

"I felt like I jumped out of the way, out of the crease," Landeskog said. "But (the referee) has a better look at it than I did. It's unfortunate. If we get one there, it's a different game."
