Arsenii Sergeev's Season of Stops, Starts & an NHL Debut
The story of the Calgary Flames’ Arsenii Sergeev is one of those interesting goalie paths that doesn’t follow a straight line. It bends, shifts levels, and, this season, briefly arrived in the NHL before circling back to the AHL again.
Sergeev has spent his entire development in North America.
If you go back far enough, the pattern is clear: Sergeev has been a North American goalie almost from the start. Drafted by the Calgary Flames in the seventh round of the 2021 NHL Draft, he spent his developmental years bouncing through the North American Hockey League (NAHL), United States Hockey League (USHL), and NCAA ranks. He’s been a steady climber rather than a goalie who’s exploded onto the scene.
There were signs along the way. In the USHL with Tri-City in 2021–22, he posted a strong .918 save percentage and 2.08 GAA over 41 games. At UConn and later Penn State, he settled into a more structured NCAA game, showing consistency rather than dominance. Still, there was enough stability to keep NHL eyes on him.
The 2025-26 season was Sergeev’s turning point.
He started the year in a crowded Flames goaltending system and found himself moving between three levels. In the ECHL with Rapid City, he showed flashes of control (.922 save percentage). In the AHL with the Calgary Wranglers, it was tougher going. He put up a 5–13–8 record with a 3.29 GAA. It was a stat line that reflected both workload and growing pains more than pure ability.
And then, unexpectedly, came the NHL moment. Called up late in the season, Sergeev made his debut for Calgary and stopped 27 of 28 shots in a 3–1 win over Los Angeles. It wasn’t just a debut — it was a composed one. He showed calm crease play, controlled rebounds, and a performance that suggested there is something real underneath the AHL numbers.
Of course, it didn’t change his trajectory overnight. Shortly after, he was reassigned back to the Wranglers, continuing the long development arc that most goalies in his draft range experience.
Where does his season leave him?
Sergeev is still developing, climbing, and is still very much in the “learn the position at pro speed” phase. But he’s also a goalie who has already seen NHL action, already handled the moment, and already shown he can step into a game without it overwhelming him.
For a seventh-round pick, that alone keeps the story alive.
