DENVER -- David Jones scored with 16.4 seconds left in overtime, and the Colorado Avalanche beat the St. Louis Blues 1-0 Wednesday night.
Defenseman Matt Hunwick brought the puck into the zone and dropped it to Jones, who beat Jaroslav Halak with a deflected shot to give Colorado its second consecutive win.
Semyon Varlamov stopped 33 shots for his second shutout of the season and the 10th of his career.
Halak had 19 saves and lost for the first time in six games this season.
The Avalanche (7-7-1) scored six goals in a wild win Monday but had only four shots midway through Wednesday's game. The Blues didn't generate many more chances than Colorado but had a 24-10 advantage in shots heading into the third.
Neither team was whistled for a penalty until Colorado's Tyson Barrie drew a minor for hooking midway through the second period.
Halak, playing in his first game since suffering a groin injury Feb. 1, was sharp when he needed to be to keep the game scoreless into overtime.
Varlamov was more tested but kept the Avalanche in it by stopping 31 shots in regulation.
The Blues (9-6-2) nearly broke through with 12 minutes left when former Colorado forward Chris Stewart was alone in front of the net, but Stewart shot the puck wide.
A minute later, St. Louis rookie Vladimir Tarasenko left the game after taking a hard hit from Mark Olver.
Colorado played the third period without forward Milan Hejduk, who suffered a torso injury in the second period.
