Flames 2, Oilers 1 (OT): Jiri Hudler scored at 3:14 of overtime as visiting Calgary evened this season's installment of the Battle of Alberta at one win apiece.

Lee Stempniak tallied in regulation for the Flames, who dropped a 4-2 decision to Edmonton at home on Nov. 16. Reto Berra turned aside 30 shots as Calgary won for the third time in four contests.

Taylor Hall scored in the final seconds of the third period for the Oilers, who are 1-1-1 on their five-game homestand. Devan Dubnyk finished with 25 saves but was unable to deny Hudler, who beat him from alone on the right side after receiving a pass from the top of the left faceoff circle by defenseman Kris Russell.

As Matt Stajan and Oilers captain Brad Ference battled for the puck along the boards near the blue line, Stempniak walked in and grabbed it. The veteran skated into the right circle before unleashing a shot that beat Dubnyk to the short side for his sixth goal of the season.

With Berra 10.1 seconds away from his first NHL shutout, Perron picked up a loose puck near the left post and - while standing below the end line - fired it behind the goaltender's back and across the crease to Hall, who buried it from below the left circle to forge a tie.
