Aidan Maldonado

Aidan Miller is a 21-year-old top prospect in the Philadelphia Phillies organization who has been sidelined since late 2025 with a lower-back injury. He initially began rehabbing in spring training 2026 but experienced recurring back problems. After showing some progress with fielding ground balls and rotational exercises in April, Miller suffered a setback in May and was shut down from all baseball activities. The exact nature and diagnosis of his back injury remains unclear. His prospect value has diminished significantly due to the prolonged absence and uncertainty surrounding his recovery timeline. There is no clear timetable for his return to play.
