GLENDALE, Ariz. -- Ryan O'Reilly and Jarome Iginla scored 29 seconds apart in the first period, Semyon Varlamov made 27 saves, and the Colorado Avalanche beat the Arizona Coyotes 5-2 on Thursday night for their third straight win.
Freddi Hamilton added his first NHL goal, and Matt Duchene and Gabriel Landeskog also scored for the Avalanche, who won for the 11th time in 15 games to remain seven points behind Calgary for the final Western Conference playoff spot.
Oliver Ekman-Larsson scored twice for the Coyotes, who have dropped four straight and 16 of 17.
Arizona's Louis Domingue stopped 24 shots in his third NHL start in an intriguing matchup against his former juniors coach, Colorado's Patrick Roy. The Hall of Fame goalie last year blamed a 2012 playoff series loss on Domingue, who replied that Roy was "one of the worst people I've ever met."
Before taking over in Colorado last season, Roy spent eight years as the owner and coach of the Quebec Remparts juniors team. Asked last year how they blew a 3-0 series lead to Halifax in the 2012 playoffs, Roy said, "Bad goaltending."
Domingue responded with a series of tweets in French in which he said Roy "intimidated me verbally day after day."
In a later radio interview, Domingue said he "didn't get any of the help I needed" from Roy as a coach.
Coyotes coach Dave Tippett gave the 23-year-old Domingue his third NHL start against Roy's club, less than a month after he was called up from the minors.
Domingue wasn't tested early, as Arizona dominated and took a 1-0 lead when Sam Gagner threaded a cross-slot pass to Ekman-Larsson, whose wrister beat Varlamov at 3:24 for his 50th career goal.
But the Avalanche woke up and got some help from Domingue.
O'Reilly scored at 8:15 after Domingue stopped his initial shot, but the puck trickled through him, and he inadvertently kicked it in.
Less than 30 seconds later, Iginla beat Domingue between the pads for his 23rd, giving Colorado two goals on four shots.
In his seventh game with Colorado and eighth in the NHL, Hamilton redirected Brad Stuart's blast midway through the second period to give Colorado (77 points) a cushion on a night the Avalanche didn't get any help.
Winnipeg (84 points) won, as did Calgary (83), San Jose (78) and Dallas (76) in the crowded playoff race.
The Coyotes long ago faded from contention, and a series of trades left them depleted offensively. They have lost 13 of 14 at home, with their last regulation win there on Jan. 8.
Ekman-Larsson's second goal came off a deflection midway through the final period that was confirmed by a video review.
Ekman-Larsson's 19 goals are the most among NHL defensemen.
NOTES: Arizona's Joe Vitale had a goal disallowed early in the third period when a video review determined he kicked in the puck. ... Colorado C Joey Hishon (elbow) was scratched. ... Arizona RW Martin Erat (upper body) left after the second period. ... Coyotes captain Shane Doan earned an assist in his 1,384th game, tying him with Larry Robinson for 37th on the NHL career list.
