The Laval, Quebec, netminder made 24 saves through the first two periods, but he was on top of his game when he needed to be in the final frame.
"I thought it was pretty tight checking the first two periods," head coach Jared Bednar said. "There weren't many scoring chances by my count either way. When there were chances, guys got sticks on pucks and blocked some shots. But there were certainly chances in the third, early in the third for Pit. They made a push there."
Bernier made 15 saves in the last 20 minutes, and his best might have come from a hard shot by Sidney Crosby at the right side 3:20 into the period.
Crosby's shot was part of a barrage by the Penguins to begin the last stanza, but the Avalanche did a good job of keeping them to the outside and quickly clearing out rebounds.
"We blocked some shots. We were smart to not give up that middle. Most of their shots were from the outside," Bernier said. "Sid had a one-timer there in the third. That was probably my only big save of the game."
Bernier was playing in his first outing in just over a week, as he last took the crease on Dec. 3 against the Dallas Stars. He wasn't able to finish that contest, as he made five saves on nine shots before being replaced midway through the second period by Semyon Varlamov.
"I thought Berns was really good. Really good bounce-back game for him after his last outing," Bednar said.
