Make it five straight wins against the Pittsburgh Penguins.
Mark Giordano scored the game-winner 2:41 into overtime Thursday night to give the Flames a 2-1 victory over the defending Stanley Cup champions.
The goal was the sixth regular season overtime winner of Giordano's career - a stat he continues to add to for the most overtime goals by any Flames defenceman.
Calgary has swept the Pens the last two years in their two-game series, and are now halfway to another 2-0 run in 2017-18.
Mike Smith made 19 first-period saves and ended the night with 43 stops, being named the game's first star.
Sean Monahan scored just seven seconds into a powerplay at the 15:43 mark of the third period to put Calgary up 1-0, with Johnny Gaudreau picking up an assist for his team-leading 16th point. He is now tied for sixth in league scoring.
Patric Hornqvist tied the game with just 1:12 to play, tipping a Kris Letang shot past Smith.
Tristan Jarry had a solid night in net for the visitors, turning aside 32 of the 34 shots he faced.
Carl Hagelin had a great chance in the first on a breakaway, cutting in from the halfboards and trying to go forehand, backhand five-hole as he cut across crease but Smith closed the wickets.
In the second, Smith managed to stop Bryan Rust in tight, after Rust took a pass from Malkin and drove around TJ Brodie to the net.

Despite playing the night before in Edmonton - a 3-2 win over the Oilers - the Pens came out flying in the first period and doubled the Flames up in shots.
The Flames outchanced the Pens in the second, though, holding a 14-10 edge in shots.
Dougie Hamilton had a great chance in the frame to open the scoring but Jarry got a piece of his point shot.
Later in the period, Micheal Ferland walked in but couldn't snap it past Jarry.
Mark Jankowski had a glorious chance to score his first NHL goal when he was sprung on a breakaway thanks to a great pass from Curtis Lazar and tried to tuck it past Jarry but was denied.
Troy Brouwer played in his 700th regular-season game Thursday night … Mikael Backlund remains two goals shy of 100 for his career … Jaromir Jagr missed his fifth game last night with a lower-body injury. Jagr, of course, was drafted fifth overall by the Pens back in 1990, winning two Cups and racking up 1,079 points (439 goals, 640 assists) in 806 games with the team. Tonight's tilt was the third straight for the Flames against a team Jagr has played on. Sunday night's game against the Devils will make four in a row … Giordano is just nine points away from passing Robert Reichel for 14th in all-time scoring for the Flames. He's 26 games away from leapfrogging Jim Peplinski for the sixth-most games played in franchise history.
