Thomas is set to become the 25th captain in Blues history, the team announced Wednesday.
Thomas is taking over for Brayden Schenn, who was traded to the Islanders in March. The 27-year-old Thomas is entering the fourth campaign of his eight-year, $65 million contract, so he's set to wear the 'C' for years to come. He had 25 goals and 64 points in 64 regular-season outings in 2025-26, which made it his fifth straight regular season with over 60 points.
