A few moments after he had passed a penalty, Carl Soderberg picked up the puck and sent a pass to Rantanen, who passed the line a shot past Mike Smith before being bullied by teammates.
Colorado beat JT 2-0 in the third hour Compher started the comeback with a rebound and Rantanen built a power play goal with a 2-50 goal.
Elias Lindholm and Derek Ryan had goals for the Flames, the top seed in the west. You'll have to experience a must-win scenario when the series returns to Calgary on Friday for Game 5. The Flames are trying to avoid a similar fate as Tampa Bay, the number one player in the East who lost to Columbus in the first round.
Philipp Grubauer stopped 35 shots, including one in left-padded OT, while continuing to stretch out the ice.
Smith had another busy night with 49 of 52 shots. In Game 3, he had suffered a 6-2 defeat.
Smith, 37, seemed to be skating when Avalanche striker Colin Wilson entered him in the first period. Smith was checked out briefly before settling in a groove.
Grubauer had the biggest salvation of the night at the beginning of the overtime, while he stood on the ice and Mikael Backlund with the puck on his stick. Grubauer waited a moment, lightly raising his left side just as Backlund shot at it. The puck hit the middle of Grubauer's block.
Compher had an outlier in overtime and Smith played by coming off the net to challenge him. Compher came around Smith just to send the puck far. Later, Colorado resisted a penalty for Ian Cole for delay after dropping the puck.
Calgary seemed to be in control after Ryan increased the lead to 2-0 and left 13:02. Just over a minute later, Compher sent a shot past Smith after battling in front of the net. Then Rantanen gave a shot to tie him up. The Avalanche had a chance to win the regulation when the Flames delayed the game penalty but could not capitalize on it.
Lindholm scored his first goal in the series at 3:25 of the second half. Only six seconds after his penalty for Erik Johnson his goal was scored. The Flames have at least one Power Play goal in all four competitions.
Shortly after Lindholm's goal, Smith shot a shot from Avalanche captain Gabriel Landeskog with his left arm. And shortly thereafter Landskog struck a shot from the post.
Smith resisted a flood of shots in the first period – plus a fall with Wilson erasing and skateboarding first in Smith. Both landed on the ice as coaches came out to look for Smith.
This undoubtedly caught the attention of Colorado: Columbus angered Tampa Bay in the first round of the Eastern Conference. The Avs hope to follow the lawsuits against the flames.
"It does not happen often," Rantanen. "It can happen in the NHL, the differences are not very big."
Flames D Juuso Valimaki played in his first game of the series. Avs F Derick Brassard (illness) and D Samuel Girard (upper body) were scratches. Avalanche rookie defender Cale Makar recently signed a huge Flames fan. But now that he's playing against her, he's getting a lot of good-natured ribbing. "Everyone was so supportive," he said.
Back to Calgary for Game 5 on Friday.
