Aidan Miller - MLB News, Rumors, & Updates

Slated for back surgery Miller will undergo a radiofrequency ablation of the facet joints in his back Friday and is expected to be sidelined 6-to-8 weeks, Paul Casella of MLB.com reports.

Impact Miller might have pushed for a promotion to the majors by now had he been healthy and performing well at Lehigh Valley. Unfortunately, he's been sidelined all season with nagging back problems, and a decision was made to have the minimally invasive procedure after he visited with multiple spine specialists. The top prospect will rest for one week before beginning the rehab process, and he could be ready to play for Triple-A Lehigh Valley as soon as late July.

Shut down again Miller (back) is no longer doing any baseball activities, MLB.com reports.

Impact Miller had resumed light baseball activities as of mid-May, but he's since been shut down altogether for the second time during his rehab. The 21-year-old top prospect has been on the shelf since February due to a balky lower back, and he just can't seem to get to the bottom of the issue. At this stage, it's unclear if Miller be able to get back onto the field at any point in June.

JUNE 1 • ROTOWIRE

Resumes baseball activities Miller (back) has resumed light baseball activities, Paul Casella of MLB.com reports.

Impact Miller had been shut down from baseball activities for roughly the past two weeks, so it's encouraging to hear he's back to progressing in some capacity. The 21-year-old top prospect has been plagued by a lower-back injury since February, and his return to action still doesn't seem to be particularly close. The Phillies are likely to continue taking a cautious approach with Miller's recovery going forward.

MAY 20 • ROTOWIRE

Return not imminent Miller (back) is no longer doing baseball activities, MLB.com reports.

Impact Miller was fielding ground balls in April but since appears to have been shut down. It's unclear if the 21-year-old top prosect has suffered a setback in his rehab from a nagging lower-back injury, or if the Phillies are being simply cautious with his recovery. In any event, Miller doesn't look to be close to making his season debut.

MAY 9 • ROTOWIRE

Still hasn't resumed batting Miller (back) is nearing a return to swinging a bat, Todd Zolecki of MLB.com reports.

Impact Miller has been "doing everything except for swinging," according to Phillies manager Rob Thomson, including fielding ground balls. The team is hoping to get the 21-year-old back swinging a bat this week as he continues to work his way back from lower-back soreness, which has plagued him since February.

APRIL 19 • ROTOWIRE

Not swinging bat yet after all Miller (back) has yet to resume swinging a bat but has begun rotational exercises, Todd Zolecki of MLB.com reports.

Impact A previous news item indicated that Miller had started to swing a bat, but the Phillies clarified that report in stating that it hasn't happened just yet. The top prospect is still rehabbing a back injury that dates back to last year, and it's unclear when he might be ready to suit up for Triple-A Lehigh Valley.

APRIL 13 • ROTOWIRE

Resumes taking swings Miller (back) has resumed swinging a bat, MLB.com reports.

Impact Although it's an encouraging step forward for Miller, there remains no clear timetable for his return to game action for Triple A Lehigh Valley. The 21-year-old shortstop, who is Philadelphia's top prospect, has been nursing lower-back soreness since spring training and figures to be brought along slowly amid his recovery.

APRIL 9 • ROTOWIRE

Not yet taking swings Phillies manager Rob Thomson said Tuesday that Miller (back) has increased his rehab activities but is not yet swinging a bat, Todd Zolecki of MLB.com reports.

Impact The nagging back injury has been bothering Miller going back to the fall, and his baseball activity is apparently still pretty limited as he's opened the campaign on Triple-A Lehigh Valley's injured list. Once cleared for all activities, the 21-year-old top prospect will need some time to build up to game readiness after missing all of spring training.

MARCH 31 • ROTOWIRE

Won't be ready for start of season Miller (back) is unlikely to be ready for Triple-A Opening Day, Charlotte Varnes of The Athletic reports.

Impact This back issue for Miller cost him the Arizona Fall League, most of spring training and it sounds like he'll be on the shelf indefinitely at Triple-A to start the year. Assuming he can eventually get right, Miller will have some rust to knock off, but he doesn't need much more minor-league seasoning before he's ready to help the big club.

MARCH 17 • ROTOWIRE

Reassigned to minors camp The Phillies reassigned Miller (back) to minor-league camp Thursday, Lochlahn March of The Philadelphia Inquirer reports.

Impact Miller has been held out of Grapefruit League play this spring due to a back issue, and it's unclear when he might be ready to play in a game. The top prospect has a good shot to debut at some point this season for the Phillies, but he'll need to get healthy first.

MARCH 12 • ROTOWIRE

No timeline for hitting resumption Phillies manager Rob Thomson said Wednesday that there's no timetable for when Miller (back) will resume swinging a bat, Lochlahn March of The Philadelphia Inquirer reports.

Impact Miller has been receiving treatment for lower-back soreness and is ramping up his activity level in the weight room. However, with no timeline for when he'll be allowed to hit again, it sounds like it could be a while before we see the top prospect in Grapefruit League action. Miller entered camp as a long shot to make the Phillies' Opening Day roster and the back injury makes it close to a foregone conclusion that he's ticketed for Triple-A Lehigh Valley.

FEBRUARY 25 • ROTOWIRE

Dealing with back soreness Miller is battling lower-back soreness and will be receiving treatment during the week, Scott Lauber of The Philadelphia Inquirer reports.

Impact It's not quite clear when this issue popped up for Miller, but the team is understandably proceeding with caution to ensure the injury doesn't get worse. The 21-year-old received an invitation to big-league camp and has an outside chance to make the Opening Day roster, but this injury won't help his chances. Miller can be considered day-to-day until the team has another update to share.

FEBRUARY 22 • ROTOWIRE

Nets invite to spring training The Phillies have extended Miller an invitation to big-league camp during spring training, Matt Gelb of The Athletic reports.

Impact It's the second straight year with a big-league camp invite for Miller, who slashed .264/.392/.433 with 14 home runs, 59 stolen bases and an 82:123 BB:K over 116 games between Double-A Reading and Triple-A Lehigh Valley in 2025. Miller has only played shortstop in pro ball and Trea Turner has that position locked down with the major-league club, so the 21-year-old is likely to return to Lehigh Valley to begin the 2026 season.

Impact There doesn't seem to be any concern that whatever physical issues Miller is dealing with will linger, but the Phillies have decided it's best to give their top prospect some rest. Miller slashed .264/.392/.433 with 14 home runs and 59 stolen bases between Double-A Reading and Triple-A Lehigh Valley in 2025 and could be ready to make his major-league debut with Philadelphia next season.

SEPTEMBER 9, 2025 • MCALL.COM

Climbs to Triple-A The Phillies promoted Miller from Double-A Reading to Triple-A Lehigh Valley on Monday, Todd Zolecki of MLB.com reports.

Impact After earning a pair of promotions in 2024, Miller had up to this point spent the entire 2025 season at Reading, slashing .259/.382/.427 with 13 home runs, 52 stolen bases and a 14.9 percent walk rate over 489 plate appearances. Miller had opened September by going 8-for-19 with two extra-base hits, two stolen bases and a 9:4 K:BB in six games, with his hot start to the month convincing the Phillies that he was ready for a stiffer test. Though Miller is likely to remain at the Triple-A level for the rest of the season, a call-up to the big leagues can't be completely discounted if the hamstring strain that star shortstop Trea Turner suffered in Sunday's loss to the Marlins proves to be a long-term concern. For now, Edmundo Sosa would appear to be the top choice to step in as the Phillies' everyday shortstop if Turner is forced to go on the injured list.

Running wild at Double-A Miller is slashing .261/.400/.457 with three home runs and 16 steals in his last 25 games for Double-A Reading.

Impact Miller was known more for his bat than his speed when the Phillies selected him in the first round a couple years ago, but he's been running wild this year for the Fightin Phils. He got off to a slow start at Double-A, but Miller has come on strong lately and is walking at an 18.3 percent clip over this 25-game stretch. Miller has only played shortstop since getting drafted, but there's a chance he will eventually move to third base.
