Jean-Sebastien Giguere made 39 saves and the Avs shut out the Bruins 2-0 to stay perfect on the year

Jean-Sebastien Giguere was brilliant in goal for the Avalanche on Thursday night, keeping Colorado unbeaten on the young NHL season with a 2-0 shutout over the Boston Bruins at TD Garden.

Making his first start of the season, Giguere was a commanding presence in upping the Avs' record to 4-0, stopping all 39 Boston shots.

"I wasn't perfect in any way," said Giguere, whose win was the 252nd of his career and 37th shutout. "There's things that I would like to improve. But overall, this is a pretty tough building to come in and win, so I'm pretty happy with the result."

Ryan O'Reilly's late first-period goal stood up for Giguere, who faced 29 Bruins shots in the final two periods while the Avs put 16 on Boston in that span.

O'Reilly's redirect of Andre Benoit's shot from the point on the power play gave the Avs a 1-0 lead with 40 seconds left. Matt Duchene added an empty-netter with 26 seconds left.

"Our defense did a super job. They put a lot of pressure on our D. I could tell after the second they were tired," Roy said. "I asked the forwards to do a little more in the third and we put more pucks deep and got a pretty good forecheck."

Roy said the Avs wanted to "shock the hockey world," and so far, so good on that.

O'Reilly, whose goal was his second of the year, said the Avs can't start reading their press clippings too much right now. Nothing has been accomplished, he said, except a good start.

"We're not getting too high or too low," O'Reilly said. "We're trying to learn and just come together. It's fun, but every night is a battle."
