BOSTON -- Matt Duchene's offense returned much sooner than even he expected.

After totaling one goal and two points over 10 games last month, the Colorado Avalanche center has erupted for six goals and nine points through six games in November.

"I didn't think it would be like this, but I'll take it for sure," Duchene said after his go-ahead wrister midway through the third period helped the Avalanche erase a two-goal deficit and earn a 3-2 victory over the Boston Bruins on Thursday night at TD Garden. "I think the puck's just bouncing a little bit. I'm just trying to put as many on net as I can. You know, early in the season for me it wasn't bouncing at all, and I knew if I just stuck with it, stay positive and didn't grip the stick too much, eventually they'd start (to) go in."

Duchene finished off a pass from center Mikhail Grigorenko at 6:39 of the final period after center Ben Street forced a costly turnover from Bruins defenseman Kevin Miller.

Colorado (6-9-1) has now won eight consecutive games in Boston.

"It's not easy to be down 2-0, but I thought we played a really good game for 54 minutes," Colorado coach Patrick Roy said. "It was a solid team effort tonight."

Swedish center Carl Soderberg, playing his first game back in Boston since leaving the team in free agency last June, and defenseman Francois Beauchemin also scored goals for Colorado, which is now 2-6-1 in one-goal games this season.

Goalie Reto Berra, who started in place of Semyon Varlamov after the Avalanche's top netminder tweaked a groin injury during practice at nearby Boston University, made 25 saves.

Colorado defenseman Erik Johnson recorded his 200th NHL point on a second-period assist while veteran right winger Jerome Iginla, who also spent time with the Bruins, tallied an assist on Soderberg's goal to move him into 37th place on the NHL'a all-time points list.

Defenseman Zdeno Chara and center Ryan Spooner each netted a goal for the Bruins (7-7-1), who opened their season-long five-game homestand with a loss.

Boston goalie Tuukka Rask, who had 27 saves, has given up 27 goals in seven games at home this season.

Chara kicked off a busy opening period with his second goal of the year on a blue-line slap shot in front of the left point, putting the Bruins ahead 1-0 just over a minute in.

Roy challenged the call after Berra was consumed by the scrum in front of the net, but the goal was upheld.

Boston capitalized on an early hooking penalty as Spooner went top shelf to double the lead 5:51 into the first, giving the Bruins their eighth straight game with a power-play goal.

"The first six to 10 minutes, we seemed to be handling the momentum of the game in our favor," Bruins coach Claude Julien said, "but then once it got the other way instead of grinding it out -- some nights you have to do that -- give them credit."

Soderberg beat old teammate Rask for a high glove-side goal to make it 2-1 at 12:08 of the first, and Beauchemin evened the score at 2-2 on his goal with 28.2 seconds left in the period.

"We got down early. We weren't playing our best," Duchene said. "They were working us bad, and we were able to get a big one from Soderberg and then a big one from Beauch and climb back in, and from there we settled in."

Colorado left winger Gabriel Landeskog received a match penalty and was ejected with 14:14 remaining in a scoreless second period after a cross-ice hit to the head of Bruins left winger Brad Marchand, who stayed in the game.

"There was no intent to injure," Landeskog said, "and I'm happy he didn't get hurt."
