CALGARY -- Bob Hartley had to wait a little bit longer to get his most recent one, but he's got career win No. 400.
Sean Monahan scored the game-winner 1:47 into overtime and Karri Ramo made 26 saves to allow the Calgary Flames to rally for a 4-3 victory against the Colorado Avalanche at Scotiabank Saddledome on Thursday.
"It's well-deserved," Monahan said of Hartley's milestone. "That's a big one for him. Obviously he used to be there (in Colorado). Right now, we're rolling. Even as a group we knew we had to find a way to win that one. We approach every game the same way, and obviously it's nice to do that for him, but at the end of the day, every game is important right now. We're finding ways to get the two points."
It was the NHL-leading sixth time the Flames have come back to win a game when trailing after two periods. It also extended Calgary's winning streak to four games. With two more Thursday, the Flames have scored an NHL-leading 39 third-period goals.
The win Thursday was Hartley's 71st as Flames coach. He's the 12th active coach and 33rd in League history to win 400 games.
It was fitting that Hartley's 400th win came against the Avalanche, the team he coached to 193 victories from 1998-2003.
"It makes it special because the guy across gave me many wins," Hartley said of Avalanche coach Patrick Roy, who played goalie for Colorado under Hartley.
Hartley also won 136 games with the Atlanta Thrashers.
Following the game, Hartley was given Calgary's fire helmet, a symbolic award given to the hardest-working member of the Flames.
"I can't stand behind the bench by myself. I have great partners. I have great players," he said. "That's the beauty of this sport, it's a team environment. I don't coach for my own record. I coach for my team. I never say that I won championships, I say that my teams won championships. You have to stay very humble in those moments because there are always tough times."
The game marked the second return to the Saddledome for Jarome Iginla, who played 16 seasons with the Flames (1996-2013) and is Calgary's all-time leader in games (1,219), goals (525) and points (1,095). Iginla has scored 268 of his 564 NHL goals and 570 of his 1,182 career points at Saddledome.
It's the first time he's lost in the rink as a member of the opposition; he faced the Flames in Calgary with the Boston Bruins last season.
"They got a good push," Iginla said. "That's what happens when you get on a roll; you try to ride it, and they've been winning at home and they are winning period and found a way to come in a game where we feel, from our point of view, we should have been able to hold on and win that.
"It stings for us and obviously a big win for them."
Monahan's 10th goal ended the game. The 20-year-old corralled his own rebound on the doorstep near Avalanche goaltender Semyon Varlamov and lifted it into the virtually empty net to win it.
"I just came in delayed and [Mark Giordano] came off the bench and tried to make a play for him to get a shot," Monahan said. "I cut through the middle and he made a great pass to me and got a shot on net and found a rebound."
The Flames trailed 2-1 entering the third period, but Curtis Glencross scored at 1:14 to tie the game. Monahan forced a turnover by Tyson Barrie before David Jones jumped on the loose puck and spotted Glencross, who fired his fifth goal past Varlamov from the slot.
"They did a good job on the forecheck," Glencross said. "I came right off the bench, and [Jones] got the puck there, and I was hollering from the red line in pretty much as I was coming down the gut. He made a great pass to me, and I one-timed it and the puck went in."
Alex Tanguay, who played for Hartley in Calgary and Colorado, put the Avalanche back on top at 14:14. He took a pass off his skate in the neutral zone, stepped around Flames defenseman Kris Russell and outwaited Ramo before lifting the puck into an empty net.
But defenseman Dennis Wideman's second goal of the game, his 10th of the season, tied the game with 1:17 remaining to force overtime before Monahan's game-winner.
"We're on a pretty good hot streak here," Wideman said. "I think we keep saying it, that we don't want to continue to put ourselves down in the third, but on the positive, we keep coming and we find ways to win hockey games. Hopefully we get a little better as the season drags on here of getting leads and holding on to them."
The Flames had the two best scoring chances in an uneventful first period.
Three minutes into the game and with some pressure in the Avalanche end, Josh Jooris tipped Jiri Hudler's point shot from just in front of Varlamov, but the puck hit the post. With a little less than three minutes remaining in the period, Paul Byron spotted Michael Ferland slipping through the slot, but the rookie couldn't beat Varlamov with his redirect.
Wideman put the Flames up 1-0 with his ninth goal 2:20 into the second period.
Daniel Briere thought he tied the game 1:29 later, but video review determined that the Colorado forward used his left hand to bat the puck into the Calgary net.
The Avalanche did tie it at 13:23 when Matt Duchene knocked Wideman's centering pass to Ryan O'Reilly, springing the pair on a 2-on-1 on which O'Reilly returned the puck to Duchene, who beat Ramo for his ninth goal.
Colorado went ahead for the first time 58 seconds later. On the ensuing faceoff after an icing, Zach Redmond worked the puck out of the corner and threw the puck into a crowd; it hit Nick Holden in front of Ramo and rolled over the goal line. With an assist on the play, Michael Sgarbossa earned his first career NHL point.
The Flames pressed in the final minutes of the second trying to find the equalizer, but Varlamov, playing his first game after sitting out six with a groin injury, stood tall to take the lead into the third.
