Perdomo (hand) will start at shortstop and bat second Friday against the Cardinals, Jack Sommers of SI.com reports.
Perdomo received a cortisone shot in his left hand during the All-Star break to combat hand issues that he's dealt with over the course of his career, but it won't cause him to miss any games as the D-backs begin their second-half schedule. The 26-year-old has taken a step back this season after enjoying a breakout campaign in 2025, and he's slashing just .225/.311/.325 in 10 games since the beginning of July.
