Blues Sign Arseni Koromyslov To Entry-Level Contract

The St. Louis Blues have signed 2022 fourth-round pick Arseni Koromyslov to a two-year, entry-level contract set to begin in the 2026-27 season. This deal will move Koromyslov to North America after four seasons in Russia’s pro leagues. The contract details, per PuckPedia, are:

Koromyslov, 22, filled an important role for the KHL’s Chelyabinsk Traktor this season. He recorded 17 points, 40 penalty minutes, and a plus-four in 61 games this season. This was Koromyslov’s second season in a full-time, KHL role. His 2024-25 season was spread across three teams, with Koromyslov recording five points in 26 games with Lada, two points in seven games with SKA St. Petersburg, and 10 points in 48 games with Traktor including the postseason. He scored one goal with each team, a pattern he kept up through this season.

Despite the low-scoring, Koromyslov has never recorded a negative plus-minus across a full season. He has proved to be a reliable defender at Russia’s junior and pro levels – a knack helped along by just how much Koromyslov has improved his game as he’s moved to higher roles. He was a noticeable physical presence this season, using a long reach and hard checking to stop opponents in the neutral zone. His ability to win puck battles from Traktor’s second-pair went far in supporting a forward group with seven players who scored 35 points or more.

Koromyslov will lean on that defensive prowess to earn minutes with the AHL’s Springfield Thunderbirds next season. He joins a long list of left-defenders on the Thunderbirds roster but could offer a bit more defensive reliability than Marc-Andre Gaudet, Quinton Burns, or Michael Buchinger.  Should that professional defense carry over, Koromyslov could plant his feet behind Leo Loof on St. Louis’ depth chart in the 2026-27 season.
