Scouting Report
Updated May 19, 2026
Thomas White is the Miami Marlins' top pitching prospect (No. 14 overall prospect) who suffered an oblique injury in spring training but has returned to Triple-A Jacksonville. Early season performance shows mixed results: strong strikeout ability (22 K in 14.2 IP early season, 13.50 K/9 rate) with a mid-90s fastball and elite pitch mix (sweeper, slider, changeup, splitter). However, recent starts have been inconsistent with ERA ranging from 2.13 to 4.86 across different reporting periods, and walk rate concerns persist (11.1% walk rate in latest reports). With teammate Robby Snelling recently promoted then injured (UCL sprain), White is positioned as the next call-up candidate for the Marlins rotation, though he is not yet on the 40-man roster. Former 35th overall pick with high upside but needs to demonstrate sustained success at Triple-A before MLB debut.
