Bishop's shutout was his fifth this season. He had 17 saves in the second period, when Dallas increased its lead to 2-0 on a power-play goal by Tyler Seguin, his 32nd.
Devin Shore scored the first goal with just 39 seconds left in the first period. He skated past Calgary's Dougie Hamilton to the left faceoff circle and lifted a wrist shot over goalie Jon Gillies.

Calgary had the best chances early. In the first five minutes, Bishop stopped a 2-on-1 and Radek Faksa cleared the rebound.
The Flames had a 5-on-3 power play for 1:55 midway through the period but managed only two shots on goal.
Midway through the second period, Seguin scored on the power play, taking a cross-ice pass from Jamie Benn low in the right circle. Seguin beat Gillies with a wrist shot into the upper right corner.
On the Stars' third power play of the period, Bishop stopped 3-on-2 and 2-on-1 short-handed rushes by the Flames.
