Calgary goaltender Jonas Hiller was the star of Wednesday night's NHL action as his 49 saves propelled the Flames to an overtime win in Chicago. Meanwhile, the Edmonton Oilers' winless skid continued in Arizona.

Here's what unfolded:

Hiller saves Flames in Chicago

Have the Calgary Flames discovered the secret to beating Chicago? Last year Calgary won two of the three meetings with the Blackhawks. Their success continued Wednesday night. Despite being outshot by a whopping 50-18 margin the Flames, in the middle of a six-game road trip, upset Chicago 2-1 in overtime. Mikael Backlund notched the game winner at 4:35 of the extra session. But the game really belonged to Hiller. The Swiss vet made 49 saves — two off his career best — and allowed the Flames to escape with the victory. Here's a shot of how Hiller frustrated Chicago.

Oil leak

It's getting ugly in Edmonton. The Oilers (0-3-1) gave up the most goals in the league last season and things haven't changed to this point. After a 6-1 blowout loss to the Los Angeles Kings on Tuesday, Edmonton was beaten 7-4 by the Coyotes in Arizona on Wednesday. The Oilers have now allowed 23 goals in only four games. They've also surrendered at least five goals in every game so far. Coyotes forward Mikkel Boedker scored his first career hat trick in the win. 

Bruins too tough for Red Wings

With only four goals and a lone win in four games, the Boston Bruins were wondering when their offence would check in. While they didn't remind anyone of the high-flying Edmonton Oilers of the 1980s, the Bruins scored enough to knock off the Detroit Red Wings 3-2 in a shootout at Joe Louis Arena. David Krejci and Reilly Smith, who netted goals in regulation, also scored in the shootout. Goaltender Tuukka Rask stopped the Wings' Gustav Nyquist and Andrej Nestrasil. Not only was it tough and hard-hitting on the ice, but Bruins assistant coach Doug Houda was also in the middle of the flack. Houda caught a puck on top of his head in the second period. He returned behind the bench soon after with seven stitches.
