Ben Bishop made 38 saves to help the Dallas Stars defeat the Calgary Flames 2-0 at American Airlines Center on Tuesday.
The shutout is Bishop's fifth of the season and 24th in the NHL.
"It was awesome," Stars forward Devin Shore said. "He was our best player tonight by far, and he was steady, he was in position all the time. He was on his game and it was great to see."
Shore and Tyler Seguin scored for Dallas (36-23-4), which holds the first wild card into the Stanley Cup Playoffs from the Western Conference and trails the Minnesota Wild by three points for third place in the Central Division.
"It was a big win. Four-point game there," Bishop said. "These last 20 games, every game's going to be important. It doesn't matter how. They're going to be different every single night. You've got to find different ways to win."
Jon Gillies made 24 saves for Calgary (32-23-9), which trails the Anaheim Ducks by one point for the second wild card into the playoffs from the Western Conference. The Flames are also two points back of the Los Angeles Kings for third in the Pacific Division.
"I thought it was a pretty good effort but you can't hang your hat on a pretty good effort," Calgary defenseman Travis Hamonic said. "We've got to gain some ground."
Shore put Dallas up 1-0 with 39 seconds remaining in the first period when hesitated before shooting by Gillies. The goal came 2:14 after Shore hit the post.
"Goals are going to happen," said Gillies, who received his first loss in six NHL games (3-1-0). "Good ones, bad ones, it doesn't matter. Just have to reset and go forward."
Seguin scored on the power play to make it 2-0 at 10:04 of the second period when he took a pass from Jamie Benn and shot over Gillies' shoulder. Seguin has four points (three goals, one assist) in his past three games.
Bishop made consecutive saves on Matt Stajan at 18:57 and 18:59 of the second period. He also made glove saves on Dougie Hamilton at 10:58 and Sean Monahan at 11:05 of the third period, and stopped Matthew Tkachuk with 11 seconds remaining.
"We've got to find a way to score," Flames captain Mark Giordano said. "That's it. That's the difference tonight."
