One of the most decorated high school players in the class, Miller has represented Team USA on its 12U, 15U and 18U national teams. He won gold with both the 15U and 18U teams and led the 2022 18U team in hitting (.478). He is one of the best pure hitters in the high school class and has thunderous bat speed, a sound approach, advanced understanding of the strike zone and plus raw power projections—making him a fairly complete offensive player. Miller’s swing is a bit unique, featuring a sizable leg kick and a significant hitch and barrel tip in his load, but his hand speed and natural timing are more than enough to make it work. He is consistently on time at contact, with excellent balance and a steady head throughout the swing—with some of the most impressive track record of performance you’ll find in the class. Miller wasn’t able to add much to that resume this spring, as he dealt with a hamate injury and missed a significant amount of game time. The 6-foot-2, 210-pound third baseman has average defensive ability at the hot corner, with a plus arm that could be an asset at the position. He’s played the outfield corners at times and could profile there given his offensive upside if the game speeds up on him too much at the next level. Miller is old for the class and will be 19 on draft day, as well as an eligible-sophomore in 2025 if he makes it to campus at Arkansas.

Organization Prospect Rankings

BA Grade/Risk: 55/High.

Track Record: Before turning pro, Miller’s amateur resume was lengthy. He was a member of USA Baseball’s 12U, 15U and 18U national teams, and his .423 average was the best of the 18U group. Miller had committed to Arkansas, but the Phillies selected him in the first round of the 2023 draft and signed him for $3.1 million. He might have gone even earlier if not for a broken left hamate bone that cost him nearly all of his senior season. Miller helped Low-A Clearwater win the Florida State League in his debut, and ascended all the way to Double-A Reading during a sterling first full year as a pro.

Scouting Report: Entering the year, scouts had two questions about Miller: Would he stick at shortstop, and, if not, would he have enough power to profile at another position? In 2024, he passed both tests with flying colors. Defensively, scouts saw an athletic player with the actions, range and arm strength to stick at the position, even if his throws still need to be more accurate. In terms of impact, the righty-swinging Miller swatted 11 homers—including six at pitcher-friendly High-A Jersey Shore—over 102 games. Evaluators believe Miller will likely settle in as a hitter whose game is geared more toward impact than contact while sticking at shortstop and providing average defense. He could make his future even brighter by turning more of his hard contact into line drives and fly balls.

The Future: After an excellent season which saw him reach Double-A and cement himself as a Top 100 Prospect, Miller will likely open 2025 back at Reading. He has a future as a slugging infielder with a chance to stick at shortstop. If he has to move to third base, his bat should be plenty to profile at the position.

BA Grade: 55/Extreme

Track Record: Miller’s pedigree with Team USA is about as prolific as you’ll find. He was a part of the organization’s 12U, 15U and 18U national teams, and his .478 average was the best on an 18U team that included four other 2023 first-round picks. The Phillies used a $3.1 million bonus to break Miller from his commitment to Arkansas. He debuted with 10 games apiece in the Florida Complex and Florida State leagues in the regular season. His first pro home run was the deciding blow in the win that pushed Clearwater into the FSL finals.

Scouting Report: Miller earned a rep as one of the best hitters available in the prep class thanks to tremendous bat speed, plus raw power and an excellent understanding of the strike zone. He did an superb job controlling the zone in his pro debut, producing respective miss and chase rates of 15.4% and 14.4%. He loads the bat with a downward movement and has a bit of a barrel tip and a big leg kick, but the Phillies ultimately believed Miller offered the best prep combination of hitting ability and power in the draft. Miller will begin his career at shortstop, but the prevailing thinking both inside and outside the organization is that he will likely wind up at third base as he matures and adds strength to his already-physical frame. If that happens, his plus arm strength will be an asset at the position. He also had experience as an amateur both corner-outfield positions, where his bat would easily profile. He’s an average runner now but could slow down as he ages.

The Future: Miller should begin 2024 back at Low-A Clearwater with a chance to reach High-A Jersey Shore in the second half of the season. He has the offensive skills to profile an middle-order hitter who mans third base.
