DENVER (AP) — Ukko-Pekka Luukkonen tied his career high with 40 saves, Tage Thompson had a goal and two assists and the Buffalo Sabres opened a three-game road trip by beating the Colorado Avalanche 4-2 on Thursday night.

Rasmus Dahlin had a goal and an assist, Alex Tuch also scored for Buffalo and Tyson Jost had an assist in his first game in Denver against his former team.

Defenseman Owen Power was a late scratch after suffering a lower-body injury before warmups.

Thompson stayed hot with his 24th goal of the season, just 54 seconds into the game. He has three goals and three assists in the last two games, and ranks third in the NHL with 46 points.

Only Alexander Mogilny (30 in 1992-93) and Pat LaFontaine (29 in 1991-92) have recorded more goals than Thompson in their first 30 games of a season with the Sabres.

“A lot of poise to set that goal up and really set a tone by (Casey) Mittelstadt, Thompson and Tuch,” Sabres coach Don Granato said of his top line. “Impressive start and our guys were dialed in all the way through. It wouldn’t have been nice to chase that game.”

They added another on the power play when Tuch scored on a rebound at 7:08 of the first, his 15th of the season, to make it 2-0.

Colorado outshot Buffalo 12-8 in the second period but the Sabres got the only goal when Dahlin’s wrister from the slot beat Georgiev with 2:49 left.

“I just put my head down and shot as hard as I could,” Dahlin said. “I was happy when it went in.”

Jost, who was dealt to Minnesota at the trade deadline last season, got an ovation from the fans after a scoreboard video highlighted his five-plus years with the Avalanche.

Prior to Thursday’s game, the Sabres acquired defenseman Joseph Cecconi, a Youngstown native, from Dallas in exchange for defenseman Oskari Laaksonen in a deal of AHL players.

Evan Rodrigues and Mikko Rantanen scored for Colorado, with Rodrigues back after missing nine games because of a lower-body injury.

“I felt good,” said Rodrigues, a former Sabre. “A little sloppier than I would have liked to have been in the first, a few too many turnovers, but I thought I got better as the game went on.”

Alexandar Georgiev allowed two goals on the first three shots he faced and finished with 17 saves. The Avalanche had their two-game winning streak snapped.

“We had more and looks tonight than we’ve had probably last two games combined,” coach Jared Bednar said. “Finishing obviously wasn’t good enough. But their goalie was good; give him credit.”

The Avalanche pressed for a goal after the second intermission and finally broke through at 8:20 when Rantanen scored his 20th on an odd-man rush with Valeri Nichushkin.

Colorado pulled Georgiev for an extra skater with 3:07 left and Rodrigues scored with 1:22 to go. Cozens scored an empty-netter with 58 seconds left.

“I was just trying to be a presence in the middle,” Rodrigues said. “Cale (Makar) did a great job getting it to the net and then we just kind of crashed. I found the loose puck and just put it in.”
