Marlins Top Prospect Thomas White Sidelined by Grade 1 Oblique Strain

The 21-year-old left-hander faces a three-to-four-week recovery that clouds his readiness for Triple-A Jacksonville’s opener.

Overview

  • Manager Clayton McCullough said White will miss the rest of Spring Training after a right oblique strain was diagnosed.
  • White first felt discomfort during his Grapefruit League debut against the Blue Jays, a 28-pitch inning that included a two-run double by Kazuma Okamoto and a max velocity of 96.8 mph.
  • His return-to-mound timeline is three to four weeks, and the club will monitor his build-up before determining the next steps.
  • Jacksonville’s Opening Day is March 27, and White may need rehab starts before joining the Triple-A rotation.
  • White entered camp as a non-roster invitee and MLB Pipeline’s No. 17 overall prospect, though Miami’s rotation depth made a big league Opening Day role unlikely.
