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.

Track Record: Miller’s amateur history is long and decorated. He was a part of three of USA Baseball’s National Teams, and he hit .423 as a member of the 18U squad. That track record of success led the Phillies to call Miller’s name in the first round of the 2023 draft despite a broken left wrist that sidelined him for the bulk of his senior season at Florida’s New Port Richey High. So far, the risk has been well worth the reward. Miller has improved in every area and now stands not only as the Phillies’ top prospect but also a premier overall talent. He advanced to Triple-A in his second full season as a professional and was slated for further development in the Arizona Fall League before being pulled before Opening Day.

Scouting Report: Out of the draft, few believed in Miller’s ability to play shortstop. Now, it’s hard to find scouts who think he doesn’t have the chops to man the position for years in the big leagues. Miller’s actions have become more explosive, his footwork has steadied and his arm stroke has improved, leading to more consistent, accurate throws with plenty of zip for shortstop or third base. Now, scouts believe he can handle every type of play a shortstop would be required to make, including slow rollers, grounders deep in the hole and flies to the shallow part of the grass. About the only thing standing in his way is the presence of Phillies megastar Trea Turner. No matter where he winds up, Miller has the offensive chops to profile. He began his 2025 season back at Double-A and struggled early. Evaluators inside and outside the system attributed his slow start to an inordinately high amount of breaking balls thrown his way. Once he adjusted his approach and started letting it rip on fastballs he could handle, his fortunes began to turn. After an excellent May, Miller hit a summer swoon before producing a sweltering August and September that saw him hit .356/.491/.607 with six home runs across 36 games in Double-A and Triple-A. In time, Miller has a chance to be a well-rounded hitter who hits for average, gets on base and produces power in near-equal measure. That prognosis is a departure from his amateur scouting report that predicted power over hitting ability. The improvement stems from an ability to cover the entirety of the plate, handle multiple pitch types and a knack for knowing when to unleash his best swings. Miller is an average runner whose value on the basepaths is boosted by outstanding instincts that allowed him to rack up 59 stolen bases in 2025.

The Future: Miller was slated to get reps at third base in the AFL, and he will likely get experience there during spring training and the regular season in order to clear a path to the big leagues. Once ready, he has the skills to provide the Phillies with value on both sides of the ball.

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.
