The Rays acquired Carlson from the Cardinals on Tuesday in exchange for reliever Shawn Armstrong, Ken Rosenthal of The Athleticreports.
Carlson will receive a much-needed change of scenery after posting a .198/.275/.240 slash line in 59 games for the Cardinals this season. The 25-year-old is under team control for beyond 2024, and the Rays will attempt to return him to the form that earned him a third-place finish in voting for NL Rookie of the Year in 2021.
