Miami Marlins pitching prospect Thomas White will miss three to four weeks with a right oblique strain, the team announced Friday. The 21-year-old felt discomfort during a recent outing against Toronto and will now miss crucial early-season development time.

White, ranked as baseball's No. 18 overall prospect and Miami's top prospect by ESPN's Kiley McDaniel, was expected to compete for a rotation spot this spring. The left-hander posted a 4-3 record with a 2.31 ERA across three minor league levels last season, showing the kind of potential that made him one of baseball's most coveted young arms.

Manager Clayton McCullough described White as "a great kid" with "a good head on his shoulders" who has handled everything well. The injury represents a setback for both White's development timeline and the Marlins' pitching depth as they prepare for the 2026 season.
