The Cardinals released Showalter on Tuesday.
Showalter showed initial promise after being acquired from the Orioles in the August 2023 trade that sent Jack Flaherty to Baltimore, fanning 59 batters in 34.1 innings while holding a 2.62 ERA at Single-A Palm Beach in 2024. He's had a difficult time staying healthy and performing since then, however, and had been battered for 16 runs (15 earned) over 8.2 frames this season at High-A Peoria.

Single-A Palm Beach placed Showalter on its 7-day injured list Aug. 16 with an unspecified injury.
Showalter, 20, posted a 2.62 ERA and 1.26 WHIP with 59 strikeouts over 34.1 innings before being shut down with the injury. The Cardinals appear committed to developing him as a reliever, as he had made each of his 24 appearances out of the bullpen this season.
