Phillies Face Key Roster Decisions as Aidan Miller Emerges
The Philadelphia Phillies are approaching a pivotal offseason following the 2025 season, with major lineup decisions looming. Key contributors J.T. Realmuto and Kyle Schwarber are both in the final year of their contracts, leaving the franchise with tough choices to make regarding their future. Depending on how the season unfolds, the Phillies may be forced to shake up their core for the first time in years.
If another disappointing October run occurs, Philadelphia’s front office will likely explore all options to bolster the roster. The team has never shied away from making a splash in free agency, but how they navigate the market may depend on the development of their top prospect, Aidan Miller.
Miller’s Rapid Rise
Selected late in the first round of the 2023 MLB Draft, Miller’s stock fell due to an injury during his senior year of high school and concerns about his long-term defensive fit. However, the young infielder has surpassed expectations and quickly established himself as one of the top prospects in baseball.
Not only has Miller displayed the defensive ability to hold his own at shortstop, but his offensive game is also reaching new heights. His raw power has set him apart, with MLB.com analysts Jim Callis, Jonathan Mayo, and Sam Dykstra identifying him as the Phillies’ top power-hitting prospect heading into 2025.
“He’s turning into a better all-around hitter than some anticipated, making mechanical adjustments and better swing decisions, giving even more confidence he’s just scratching the surface in terms of tapping into his raw pop,” they wrote.
A Key Piece for Philadelphia’s Future
Miller made significant strides in his first full minor league season, launching 11 home runs across 462 plate appearances while adding 28 doubles and six triples. His rapid progression through the organization—spending time at Single-A Clearwater, High-A Jersey Shore, and Double-A Reading—has positioned him as a potential fast riser to the major league level.
His continued development will impact key players already on the Phillies’ roster. Trea Turner, Bryson Stott, and Alec Bohm could all be affected by Miller’s eventual landing spot. If his power plays up, a shift to third base becomes a viable option, but should he prove capable of handling shortstop at the big-league level, his value to Philadelphia skyrockets.
As the Phillies enter a crucial period of roster evaluation, Miller’s performance in 2025 will be closely monitored. His emergence could dictate how the team approaches re-signing veterans or making major offseason moves. For now, all eyes are on the highly touted prospect as he continues to develop into a future star.
