Thomas White Out With Oblique Strain, Injury Update

Thomas White, the Miami Marlins’ left-handed pitching prospect, just hit a snag this spring. He’s dealing with a grade one strain in his right oblique.

This injury knocks him out for the rest of Spring Training. With a three- to four-week recovery ahead, Miami’s young pitching staff suddenly looks a bit thinner.

White had been flying through the minors and even got an early invite to big-league camp. That’s why his health is on everyone’s mind right now—front office, coaches, fans, you name it.

Injury update: Grade one oblique strain and what it means for Miami

White felt discomfort during his spring debut, and pitching coach McCullough said the team decided to shut him down. They’re taking the long view, hoping to protect his arm for the future.

Even though a three- to four-week rehab could get him back early in the season, the Marlins want him to heal fully before he starts throwing hard again. The medical staff will keep a close eye on him, focusing on stride, rotation, and command before he faces hitters in games that matter.

Why this matters for Miami’s rotation plans

The injury shakes up a pretty crowded Marlins pitching group. White came into camp behind a bunch of veterans and recent standouts.

Still, you never know—injuries and roster moves could open a door for the 21-year-old if he gets healthy and sharpens his command. If his rehab goes well, he could push his way into Miami’s rotation, maybe even stick as a frontline starter down the line. That’s a big “if,” but the potential is there.

Season in review: White’s minor-league breakout and the road to the majors

White’s 2025 season was a whirlwind. He shot up from High-A to Double-A, flashing the kind of stuff that gets scouts talking.

Over 21 starts, he threw 45 1/3 innings in Double-A and posted a 1.59 ERA. That earned him a late-season bump to Triple-A, which felt like a real vote of confidence in his ceiling.

• 2025: 21 starts, 45 1/3 innings, 1.59 ERA
• Double-A strikeout rate: 39.3%
• Walk rate: 12.6%
• FIP: 2.24; xFIP: 2.54
• Late-season Triple-A exposure with a pronounced swing-and-miss tendency but notable walk concerns

His spring debut was cut short by the oblique strain. He gave up two runs on two hits and a walk in one inning, striking out one.

That outing doesn’t really show what he can do, but it does highlight how much he needs his mechanics to be right. In a small Triple-A sample last year, he struck out hitters at a wild 42.5% rate but walked 25%—so yeah, control is still a work in progress.

Scouting take: tools, swing, and control to watch

White’s arm talent jumps off the page—he can miss bats with the best of them when his command is on. The next step is turning that swing-and-miss stuff into more reliable control.

A 13.6% walk rate across the minors in 2024-25 says there’s still some polish needed, especially with his offspeed pitches and pitch sequencing. If he can get through spring healthy and the Marlins manage his recovery well, maybe he’ll find a more repeatable delivery and really harness that raw velocity and movement in games.

Looking ahead: how White fits into the Marlins’ plans in 2026

The Marlins have a pipeline with established arms like Sandy Alcantara, Eury Perez, Max Meyer, Braxton Garrett, Chris Paddack, and Janson Junk. That’s a lot of depth to lean on, honestly.

But injuries? Those can shake things up fast, opening doors for up-and-coming talents. Scouts and front-office folks will keep a close eye on White’s progress.

If his rehab goes well and he sharpens his command, White could work his way back into Miami’s rotation. He might even continue his climb toward becoming a frontline starter—though, of course, that’s never a guarantee.
