DENVER - Wojtek Wolski scored 80 seconds into overtime to lift the Colorado Avalanche to a 3-2 win over the Senators on Tuesday, halting Ottawa's five-game winning streak.

Ian Laperriere and Ryan Smyth also scored for last-place Colorado, which has won two in a row.

Ryan Shannon scored twice for the Senators as they finished their five-game road trip with a 4-1 mark.

Wolski shot a puck in from the blue line that bounced off the chest of Alex Auld. It caromed right back to a charging Wolski, who knocked it in for his 12th goal of the season.

Andrew Raycroft stopped 20 shots for the Avalanche.

Shannon now has nine career goals, three of which are against the Avalanche.

The right winger spent most of the season playing for Binghamton of the AHL before being called up on Feb. 4 to try to ignite a then- struggling Senators squad.

It was the first two-goal game of Shannon's career.

The win moves the Avs into a three-way tie with Phoenix and St. Louis for last place in the Western Conference, an unfamiliar spot for them.

Colorado (27-30-1) has never been below .500 this late in the season since moving to Denver.

Smyth rammed in a rebound early in the second period, only to have the Senators tie the game again two moments later when Shannon scored a power play goal.

Auld spent almost as much time dodging Wolski as stopping pucks in the second period. Wolski knocked the net off its moorings on two separate occasions, Auld scrambling to avoid him.

Ottawa wasted little time getting on the scoreboard, scoring 30 seconds into the game as Shannon lined a shot through Raycroft's legs.

It was Shannon's first goal since last March against Nashville.

Colorado tied the game near the end of the first period when Laperriere reached his stick into the air and tipped Cody McCormick's blast from the blue line past Auld.

Laperriere has a goal in two straight games.

The Avalanche were without defenceman John-Michael Liles (wrist) and forward Darcy Tucker (family matter).

Liles injured his wrist during a shootout win over Detroit on Sunday, and won't be with the team when they kick off a six-game, 11-day road trip at Washington on Friday night.

He "could join us by the end of the road trip, best case scenario," coach Tony Granato said.

Tucker has been out as he deals with an illness to his father back in Alberta. He'll be back with the team on the trip.

The Avalanche may have Paul Stastny back in the lineup as soon as Friday night. Stastny has missed the last seven weeks with a broken right forearm.

The centre was one of the team's top scorers when he was hurt.
