X-rays were negative on J.T. Realmuto‘s left wrist after the catcher was hit by a Yoshinobu Yamamoto fastball in the third inning of today’s 9-1 Phillies loss to the Dodgers. Realmuto remained in the game and was back behind the plate in the bottom of the third, but was replaced by Rafael Marchan before the bottom of the fourth.
After the game, Phils manager Don Mattingly told MLB.com’s Paul Casella and other reporters that Realmuto was “obviously sore, couldn’t really squeeze, wasn’t gonna be able to swing and actually had a little trouble catching, too. So, sore enough to get him out of there.” Despite this lengthy list of issues, Mattingly felt Realmuto was “gonna be okay” given the x-ray results.
The Phillies don’t play on Monday, so Realmuto has an extra day to heal up before the club begins a six-game homestand on Tuesday against the Padres. It wouldn’t be a surprise if Realmuto also sits Tuesday due to any lingering soreness, and the presence of both Marchan and Garrett Stubbs on the active roster gives the Phillies some flexibility in giving Realmuto some more rest without leaving the club short-handed at the catcher’s spot.
Realmuto missed 10 days earlier this season due to a bad back, and the veteran backstop is one of several Philadelphia hitters who has underperformed at the plate. After signing a new three-year, $45MM free agent deal with the Phillies during the offseason, Realmuto has stumbled out of the gates with a .220/.296/.299 slash line and two home runs over 142 plate appearances.
In a longer-term injury concern, Phillies GM Preston Mattingly didn’t have any new news on the status of infield prospect Aidan Miller, who has been sidelined all season due to ongoing back pain. “We’re leaning on medical. [He’s] still just doing his rehab program at this point. It’s not baseball activities, but as we’ve seen over the years, that could change pretty quickly,” Mattingly told The Athletic’s Charlotte Varnes and other reporters.
Miller dealt with back problems in the second half of the 2025 season, and played through discomfort over a two-month stretch that saw the infielder promoted to Triple-A for the first time. Miller still hit .264/.392/.433 over 526 combined PA between the Double-A and Triple-A levels, but had to finish the year on the Triple-A injured list after only eight games with Lehigh Valley.
The back soreness resurfaced again in Spring Training, and has put a halt to Miller’s fourth pro season. He has been able to play catch and take some grounders, but that has been the extent of his baseball activity for the better part of three months.
Mattingly feels Miller will be able to play before the 2026 campaign is over, though the fact that this is now even a question speaks to the uncertainty surrounding Miller’s status. The team seems to be operating with some extra caution given the lingering nature of this back problem, and how the Phillies “want him to be good to go not just this year, but the rest of his career,” as director of player development Luke Murton told Varnes.
Miller entered 2026 as a consensus top prospect in baseball, with The Athletic’s Keith Law and ESPN’s Kiley McDaniel each ranking the infielder within the top ten of their preseason rankings. It was seen as just a matter of time before Miller made his Major League debut, with the career shortstop seen as a candidate to supplant Alec Bohm at third base or Bryson Stott at second base given how Trea Turner has the shortstop position covered. This extended injury absence has thrown a wrench into all of these plans, and it may be that Miller will have to wait until 2027 to get his first taste of the majors.
It’s sounding more and more like Miller may have a need for possible surgical intervention with his back. When I had surgery on my spine it took months of non operative method attempts to get to the point that the only way to clear the issue was microdiscectomy. I’m not totally aware of what his back issues are but this just sounds oddly familiar minus the baseball activities. I hope that it’s something very correctable for the kids sake. It’s not just his career, it’s quality of life you worry about with spine issues.
Good luck, kid. Tough age for back problems…
Who said, “Spine?”
Sammy- I assumed spine, you are right I don’t know if they said if it was spinal related or muscular/soft tissue early. But some of it just sounded very much the same as the stuff I went through with cervical radiculopathy stemming from disc herniation and displacement in a car accident. I just hope it’s nothing like that for Miller. For his career sure, but more importantly the rest of his life. Back issues are not great at any age.
