‘I feel great now’: Healthy Miller headlines Phillies contingent in Fall League

Philadelphia Phillies prospect Aidan Miller is playing pain-free in the Arizona Fall League for the Surprise Saguaros following an injury-plagued 2026 season. The 22-year-old infielder was sidelined for most of the regular minor-league campaign due to discogenic pain and facet inflammation in his lumbar spine before undergoing a radiofrequency ablation procedure in June. After returning for late-season action with Double-A Reading, Miller is using the Fall League to regain live game repetitions.

Miller is transitioning defensively to third base during his time in Arizona after previously spending his professional career at shortstop. He headlines a group of Philadelphia prospects participating in the league, which also includes position players Aroon Escobar, Dante Nori, Luke Davis, and Kehden Hettiger, alongside pitchers Keegan Batka, Ryan Dromboski, Estibenzon Jimenez, Andrew Walling, and Kevin Warunek.
