Walker scored three goals in AHL Springfield's 7-6 overtime loss to Providence on Friday.
These were Walker's first points in seven outings for the Thunderbirds this season. He hasn't regularly played in the AHL since 2023-24, but he appears to be out of the mix for depth spots with the Blues. He had 11 points over 46 regular-season outings for St. Louis in 2025-26.
