Dan Hinote and Rob Blake scored in the final 58 seconds and the Avalanche beat the Blackhawks 4-3 Monday night.
Blake scored two goals and became the 17th NHL defensemen to score 200.
Patrick Sharp, Rene Bourque and Curtis Brown scored for the Hawks.
"The effort was there, but unfortunately, something weird happened, and we don't get anything out of a good performance," Brown said.
Brown gave the Hawks a 3-2 lead with 5 minutes 21 seconds left in the third when he took a centering pass from Bourque from behind the net and sent a backhander over goaltender Peter Budaj's glove.
But with 2:03 remaining, Michal Barinka was sent off for cross-checking. Blake tied it 3-3 at 19:03.
Hinote scored from a tough angle after Joe Sakic had dumped the puck into the Hawks zone. Hinote skated along the right boards and sent a shot off the back of Nikolai Khabibulin's right pad and into the net with 12 seconds left.
"I only get the lucky ones," Hinote said. "I knew there was about 15 seconds left so I just wanted to throw it to the net and maybe get a faceoff down there. I wasn't trying to score from there."
"He's right," goalie Khabibulin said of Hinote's goal. "That puck shouldn't go in. I'll take the blame for that one."
Earlier Monday, Hawks coach Trent Yawney was named an assistant coach for Canada for the world championship in May. Claude Julien and Yawney will assist Marc Habscheid in Latvia.
Yawney is completing his first year as coach of the Hawks, who will miss the playoffs.
"It's been a disappointing year for us in Chicago," said the former NHL defenseman. "But at the same time, it's the first time in five years I've been out of the postseason, so to continue in May will be exciting.
"It's a great honor to represent your country."
Yawney and Habscheid were teammates on Canada's 1988 Olympic squad. Yawney also played twice at world championships. The Hudson Bay, Sask., native spent five years as coach of Norfolk in the AHL before taking the Hawks job.
"Having experience playing over there [in Europe], although it was a little while ago, I think I can at least relate to the defense what to expect," he said.
Notes: The teams went 2-2 in the four-game season series. ... The Blackhawks are 11-25 in one-goal games. ... Sakic has a 10-game point streak. ... Budaj made his 11th consecutive start.Copyright © 2015, Los Angeles Times
