CALGARY - Jamie Benn had a goal and an assist as the Dallas Stars edged Calgary 2-1 on Friday to hand the Flames their seventh straight loss.
Trevor Daley also scored for the Stars (15-10-4), while Kari Lehtonen, starting his fifth game in a row, made 21 saves.
After being held without a point Wednesday in the Stars' 2-0 win over Vancouver, Tyler Seguin had an assist to take over the NHL scoring lead with 39 points (23 goals, 16 assists). He is one point up on Evgeni Malkin and Jakub Voracek.
Mark Giordano scored the lone goal for Calgary (17-15-2), which has lost seven consecutive games for the first time since its team-record 11-game losing skid in 1985-86. Jonas Hiller stopped 19 shots.
Dallas has won three games in a row to move within seven points of the Los Angeles Kings, who hold the final wild card spot in the Western Conference.
After a scoreless first period, the Stars took the lead for good four minutes into the second. Calgary rookie Markus Granlund won a face-off in the Flames end but Kris Russell missed the puck in front of Calgary's net, allowing Benn to reel it in and beat Hiller on a backhand.
Dallas took a 2-0 lead when Daley took a pass from Benn and burst down the right side, ripping a shot over Hiller's shoulder as the Flames goaltender dropped to the ice.
The Stars will attempt to complete a perfect three-game road sweep through Western Canada when the play in Edmonton on Sunday.
The Flames started off the 2014-15 season an impressive 17-8-2. But they haven't picked up a point since beating Colorado on Dec. 4 and have tumbled out of a playoff spot, sitting two points back of the Kings, who hold a game in hand.
Calgary's final two games before Christmas are on the road. They play in Vancouver on Saturday night before taking on the reigning Stanley Cup champions in Los Angeles on Monday.
The Flames closed the gap to 2-1 with 1:15 left in the second period on a weird goal.
After intercepting Daley's clearing attempt at the blue-line, Giordano wristed a knuckler towards the net that appeared to dip on the way and eluded Lehtonen.
Despite only being down one goal, Calgary failed to generate any sustained pressure in the third period.
The Flames' best chance came with 28 seconds left when they got a power play and had an opportunity to tie the game with Hiller pulled, but they were unable to take advantage.
Notes: Matt Stajan was a healthy scratch for Calgary for the second time in five games. ... Among those not dressed for Dallas was Jordie Benn (illness)... With 23 goals in the Stars first 30 games, Seguin had the third highest goal total through that point in team history. Dino Ciccarelli had 29 in 1986-87 and had 26 in 1981-82. ... The last time the Flames lost seven games in a row in regulation time was December 2-17, 1974, when the franchise was in Atlanta. The 11-game losing streak in 1986 included an overtime loss although at the time, overtime losses weren't worth a point, which is why it stands as the official team record for losing streak.
