Aidan Miller, the top prospect in the Philadelphia Phillies' farm system, has opened up about the back injury that has kept him sidelined during Spring Training. In an interview, Miller revealed that his back has been "super tight" but that he is making progress in his recovery and feels he is in a "better spot" than he was initially. The Phillies are taking a cautious approach with Miller, who is not expected to make the Opening Day roster, in order to ensure he is fully healthy before joining the big league club.

Why it matters

Miller is one of the Phillies' most exciting young talents, coming off a 2025 season in which he hit 14 home runs and stole 59 bases in the minors. His development is crucial to the Phillies' long-term plans, so the team is wisely taking a measured approach to his recovery to avoid any setbacks.

The details

According to Miller, the back injury was not the result of anything that happened on the field, but rather just general tightness that the training staff has been working to address. The Phillies have decided to hold Miller out of action for a few days to allow the injury to calm down, and he is now in the process of building back his strength and flexibility.

  • Miller has not played yet during Spring Training due to the back injury.
  • The Phillies are still over a month away from the start of the regular season, giving Miller time to fully recover.
