Aidan Miller Fantasy Stats

Philadelphia Phillies No. 1 prospect Aidan Miller (back) has resumed baseball activities and is expected to begin swinging a bat this week as he recovers from a lower back injury. Miller, the 27th overall pick in the 2023 draft, has yet to make his major league debut but remains one of the organization's top long-term pieces. The young shortstop owns an .817 OPS across his minor league career and has flashed advanced offensive upside. His recovery has moved slowly with limited updates, but Philadelphia will prioritize a full return. There is no official timetable for Miller's next game action.

Philadelphia Phillies infield prospect Aidan Miller (back), who is on the seven-day injured list at Triple-A Lehigh Valley to begin the year, has started to swing a bat, but there remains no timetable for his return, per MLB.com. Miller, who is the Phillies' top prospect and No. 21 overall in baseball per MLB Pipeline, is dealing with a sore lower back. The Phillies are going to play it safe with the 21-year-old shortstop. The former 27th overall pick in 2023 hit .259/.382/.427 with an .810 OPS, 13 home runs, 41 RBI, 74 runs scored, and 52 stolen bases in 108 games played for Double-A Reading in 2025. Once Miller gets healthy, he'll have a shot to eventually replace Alec Bohm at the hot corner in the major leagues, and he offers fantasy managers a more intriguing power/speed profile. He's a quality defensive shortstop prospect, but he's blocked at the major-league level by Trea Turner. Miller is a must-stash in dynasty/keeper leagues in 2026 while he rehabs his back injury.

Philadelphia Phillies top prospect Aidan Miller (back) has yet to swing a bat as he recovers from a lingering back injury, although manager Rob Thomson said on Tuesday that Miller's activities have increased, according to Todd Zolecki of MLB.com. Miller, who is considered the No. 9 overall shortstop prospect, started the 2026 season on the injured list at Triple-A Lehigh Valley due to a back injury that he's dealt with since last fall. The Phillies aren't going to rush the 21-year-old top prospect, especially after he was unable to play at all during spring training. The former 27th overall pick in 2023 hit .264/.392/.433 with an .825 OPS, 14 home runs, 42 RBI, 82 runs scored, and 59 stolen bases in 116 games with Double-A Reading and Lehigh Valley in 2025. Miller is currently blocked at the big-league level at shortstop by Trea Turner, but the Phillies will find a spot for him, potentially at third or second, when he's ready. At the rate he's going with his back rehab, Miller might not be a candidate to make his MLB debut in Philly until the second half of 2026.

Philadelphia Phillies shortstop prospect Aidan Miller (back) likely won't be ready for Opening Day at Triple-A Lehigh Valley due to an ongoing back issue. The Phils' top-ranked prospect dealt with a back injury late last year that prevented him from participating in the Arizona Fall League, and it has lingered into 2026, resulting in Miller being unable to play in any Grapefruit League games before being reassigned to minor league camp in mid March. Unfortunately, the organization has not yet provided a timetable for his return, so it's not clear when he's expected to make his 2026 debut. The 21-year-old could make his major league debut later this year if he gets going at Triple-A once he returns, and will be a top stash candidate once healthy.

Philadelphia Phillies shortstop prospect Aidan Miller (back) was reassigned to minor-league camp on Thursday. It's no surprise at this point, as the youngster has been dealing with a back issue since late February, having not registered a single at-bat in Grapefruit League play this spring, and with Trea Turner and Alec Bohm holding down the left side of the infield to start 2026. The Phillies' top-ranked prospect will likely begin the season at Triple-A, which is where he had an eight-game stint at the end of 2025 after a strong showing at Double-A. The former first-rounder hit .356 over his final 39 games between Double and Triple-A last year, carried a .392 OBP for the season thanks to a 15.6 percent BB%, and stole 59 bases in a total of 116 games. Assuming health, there's a good chance the 21-year-old will make his major league debut later this year, with work at both third base and second base this spring opening other potential routes to the big leagues, and with a fantasy-friendly power/speed toolset, the right-handed slugger is a worthy stash option in deeper leagues.

According to Lochlahn March of The Philly Inquirer, Phillies top infield prospect Aidan Miller (back) is still getting treatments on his back but remains without a clear timetable to resume hitting. March noted that the Phillies remain very cautious with the former 27th overall selection. The 21-year-old was in the mix to potentially crack the Opening Day roster, but this injury will likely send him back to Triple-A to begin the season. In 2025, Miller spent the majority of his campaign with Double-A before earning a short taste of Triple-A in the final month. Through 108 games at Reading, Miller held a stellar .259/.382/.427 line with 13 home runs and an eye-catching 52 stolen bases. In his first eight games at Triple-A, Miller swiped another seven bags while holding a .333 AVG. Even though Miller is trending towards beginning the season in the minor leagues, he remains a viable stash option for deeper leagues given the immense speed upside he possesses.

Philadelphia Phillies shortstop Aidan Miller (back) is likely going to sit out for a few days. According to Todd Zolecki, Miller is dealing with back soreness, so the Phillies plan to be careful with him. The team will take it easy with Miller while he gets treatment this week. The 21-year-old is expected to begin the season in the minors, but it shouldn't be too long before he's in Philly. In 2025, Miller slashed .264/.392/.433 with 14 home runs, 42 RBI, and 59 stolen bases in 116 games between Double-A and Triple-A. The majority of his games were played in Double-A, so Miller will likely begin the 2026 campaign in Triple-A. He could be on the short list to Philly if he shows that he can handle Triple-A pitching.

Philadelphia Phillies infield prospect Aidan Miller will take most of his spring training reps at shortstop and third base, according to manager Rob Thomson. He may also play some second base. However, the skipper shut down any chance of him playing left field. Miller was a first-round pick out of high school in 2023, and a meteoric rise through the minors resulted in him playing eight games at Triple-A last year. Between Double-A and Triple-A in 2025, he slashed .264/.392/.433 with 14 home runs, 59 stolen bases, a 15.6% walk rate, a 23.4% strikeout rate, and 137 wRC+. It seems like he'll probably open 2026 at Triple-A, but his minor league statistics and his impending spring training workload both indicate that he should make his MLB debut in the very near future. He's already generating buzz in fantasy baseball circles, ranking as the #40 shortstop in RotoBaller's latest draft rankings for 2026.

According to Charlotte Varnes of The Athletic, Philadelphia Phillies infield prospect Aidan Miller is not expected to break camp with the MLB roster. While Varnes noted that a 2026 MLB debut remains in play, he will likely not be on the team's Opening Day roster given the team's current infield depth. Miller is considered the team's No. 2-ranked prospect on MLB.com and overall No. 32 prospect in the sport. Miller joined the organization with the 23rd overall pick in the 2023 MLB Draft out of J.W. Mitchell HS. Miller spent the majority of the 2025 season with Double-A before finishing the season with a brief taste at Triple-A. Through 108 games at Double-A, Miller held a .259/.382/.427 line with 13 home runs and 52 stolen bases. During his brief eight-game stint at Triple-A, Miller posted a .333/.514/.519 line. Even though he is not expected to break camp with the MLB roster, he could become a top stash candidate in deeper category formats early in the season, given his five-category skill set.

Philadelphia Phillies infield prospect Aidan Miller earned an invite to spring training. Miller is considered one of the top shortstop prospects in the sport on MLB.com and is viewed as the team's No. 2 overall prospect. The 21-year-old joined Philadelphia in the opening round (27th overall) of the 2023 MLB Draft. The infielder began the 2025 campaign with Double-A Reading, where he held a .259/.382/.427 line with an .809 OPS. Miller hit 25 doubles, 13 home runs, and stole 52 bases. He then finished the season with a brief eight-game stint at Triple-A, where Miller posted a strong .333/.514/.519 line with one home run and an impressive seven stolen bases. Given that Miller has only had a brief stint in Triple-A, he will likely begin the 2026 season there. However, if he has a successful spring training, he may contend for an early 2026 MLB debut.
