Road to Recovery: From Clearwater to Reading Playoffs

In 2025, Miller slashed .259/.382/.427 with 13 home runs and 51 steals in 108 games at Double-A Reading and went 9-for-27 with a homer and nine walks after a late promotion to Triple-A. He was likely to open this season at Triple-A Lehigh Valley and potentially help the Phillies at the Major League level if all this went right.

However, Miller has been dealing with a back injury suffered in spring training, resulting in a minimally invasive procedure in June, which has forced him to miss virtually the entire season.

If all things go well and he continues to remain healthy, look for Miller to be a factor in the Phillies lineup sometime in 2027.

The Arizona Fall League begins on Oct. 3 and runs through the championship game on Nov. 14.
