Aidan Miller Fantasy Stats

Philadelphia Phillies shortstop prospect Aidan Miller (back) resumed light baseball activities last week, so hopefully that means he'll be swinging a bat soon, and although there has been no additional update from the Phillies since then, the 21-year-old should be on fantasy managers' stash radar if a rehab stint is on the way in the coming weeks. The Phils' top-ranked prospect has been out all year with a lower back injury that cropped up late last season and has lingered into 2026. Despite the back issue, the right-handed hitter finished strong in 2025 and put together a final slash line of .264/.392/.433 with 14 home runs and 59 stolen bases over 116 games (108 at Double-A). Proactive managers should consider stashing the former first-rounder ahead of time, as his combination of power and speed, with the likelihood of a decent batting average, gives him multi-category appeal for fantasy, which would make him a priority stash once he gets rolling at Triple-A.

Philadelphia Phillies shortstop prospect Aidan Miller (back) is beginning to make some progress in his return from a lower back issue that has kept him out of all regular-season games so far this year. The Phils' top-ranked prospect dealt with the issue late in 2025, and it has lingered into 2026, but he's finally begun to resume "light baseball activities" per interim manager Don Mattingly. The former first-rounder finished the 2025 campaign strong, hitting .356 with a 1.088 OPS from July 27 on (39 games), culminating in a .264/.392/.433 slash line for the season, with 14 home runs and 59 steals. Unfortunately, no clear timetable has been given for his return, and he'll likely need to show he's kicked the rust off at Triple-A for a while before the team decides to call him up for a big league debut. Trea Turner also stands in his way at short, so perhaps the team will look to get him some experience elsewhere on the diamond. Regardless, few can match his power-speed combo, so fantasy managers should continue to monitor his progress as the 21-year-old could eventually become the top hitter to stash in all leagues later this year.

Philadelphia Phillies prospect Aidan Miller has suffered a setback in his recovery from a lower-back injury that has sidelined him for months. He had recently resumed fielding ground balls and performing rotational exercises, but he has now been shut down from all baseball activities. It remains unclear whether the team is simply being extra cautious with its top prospect or if there is an underlying issue preventing him from taking another step forward. The 21-year-old shortstop first began experiencing back issues late in the 2025 season, causing him to miss time in the Arizona Fall League. Once the team reported to Spring Training, he began experiencing the same back problems and was subsequently shut down. He has been slowly building back up, though the team has never been able to clearly define or diagnose the issue with much detail. It remains to be seen whether he will make his Major League debut at all this season, and his value as a prospect to stash is slowly diminishing in value.

Philadelphia Phillies infield prospect Aidan Miller (back) has yet to take the field this season and is quickly losing stash value. According to a recent report by Todd Zolecki of MLB.com, the team's top infield prospect is "nearing" a return to swinging a bat. While the infielder has been able to participate in other baseball activities, he has yet to begin swinging, which remains a major hurdle in his recovery. Early in camp, Miller was in contention to compete for a starting job, but this injury prevented him from making a strong case. Last season, the former 27th overall pick from the 2023 MLB Draft spent most of his time with Double-A before earning a short taste with Triple-A. With Double-A (108 games), Miller posted a .259/.382/.427 line with 13 home runs and 52 stolen bases. Over his short eight-game stint with Triple-A, Miller stole seven bags while holding a .333 AVG. While he still has a potential length recovery ahead of him, Miller remains in play for a second-half MLB debut.

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.
