DALLAS -- Marty Turco was challenged by his coach to improve after consecutive subpar performances, and he responded.
Dallas, which had lost its two previous games by the combined score of 12-4, rebounded with a solid effort against Calgary.
"He played a very solid game," Stars coach Dave Tippett said. "He did a lot of the things we talked about. He gave us a chance to win, and that's what we expect from him."
Turco, who won his 100th NHL game, was pulled in the Stars' 7-2 loss to Los Angeles on Thursday after giving up three goals on seven shots in less than 9 minutes. He allowed five goals in his previous game, a 5-2 loss at Vancouver on Sunday.
"He has his expectations, and you have to meet those challenges or you won't make it in this league," Turco said of coach Tippett. "You don't want to be challenged because you did something wrong, but the challenge is there regardless whether he brought it up or not."
Morrow, who also had an assist, scored at 5:55 of the third period. It was his second of the year and the 99th of his career. Defenseman Phillipe Boucher took a slap shot from the blue line that Antti Miettinen deflected before Morrow redirected it again just in front of Calgary goalie Miikka Kiprusoff.
"Both our goals were hard plays at the net," Tippett said. "Brenden goes hard to the net -- just grit plays. You do those enough, and you get rewarded."
Although the Flames scored a power-play goal, the Stars' penalty-killing unit played a key role, stopping a two-minute 5-on-3 Calgary advantage late in the second period and early in the third.
"You don't want to be in that situation at that point in the game," Turco said. "Huge kill for us."
Dallas was 8-of-9 on the penalty kill and had killed off 17 straight Calgary power plays over their previous four meetings before Tony Amonte snapped the streak on a 5-on-3 in the first period.
"We had our opportunities," Calgary captain Jarome Iginla said. "You want to score when you have a 5-on-3 for 2 minutes. We've got to find a way to score there, but it's more than just the power play. We have to generate more offense."
Calgary opened the scoring at 2:17 of the first period after Dallas got into penalty trouble early, leading to Amonte's goal. He was camped in front of Turco on the 5-on-3 power play and deflected in Roman Hamrlik's slap shot from the blue line just one second before the first Dallas penalty was to expire.
The Stars answered at 16:13 of the first when Jason Arnott scored his second goal of the season. Arnott was standing at the top of the crease and swept in a nifty backhand from Morrow.
"We played well enough to win" Flames coach Darryl Sutter said. "Both scores were off deflections. Turco was great, but our skill guys have to produce."
- The Stanley Cup was in the building for a promotion, and fans were charged $15 to get their picture taken with it.
- Stars defenseman Sergei Zubov missed his second straight game with back spasms. Stars coach Dave Tippett said he should be ready for Dallas' next game against San Jose on Wednesday.
- Flames winger Darren McCarty was laid out on a check by John Erskine late in the second period and did not return. "He got his bell rung," coach Darryl Sutter said. "He wanted to go back in, and we said no." There was no penalty on the play.
