Aidan Miller set to begin rehab assignment with Clearwater Threshers

Philadelphia Phillies infield prospect Aidan Miller is set to begin a rehab assignment with the Low-A Clearwater Threshers. This marks his first game action of the 2026 season after being sidelined by a back injury since September 2025.

Reports indicate the plan for his return involves playing five innings at shortstop. Miller has undergone medical consultations, procedures, and extensive therapy to prepare for his return to the field. Following this assignment, the organization is considering a potential stint with the Triple-A Lehigh Valley team and a possible assignment in the Arizona Fall League this offseason.
