Miami Marlins Top Prospects for 2026

1. Thomas White, LHP, 21, 6’5”/240, AAA

A 2023 comp-A round pick, White has flourished and gotten better year over year. The 2025 season saw White reach Triple-A and pitch 89.2 innings across three levels, posting a 2.31 ERA with a 38.6 percent strikeout rate and a 13.6 percent walk rate. Something clicked post All-Star break as White struck out 76 batters in nine starts, good for a 42.5 percent strikeout rate.

White dominates with a big fastball from a low-effort delivery, currently sitting around 96, but has gotten up to 99, on occasion, playing better at the top of the zone with its ride. The pitch averaged nearly 16 inches of IVB from a sub-six-foot release height and high spin rates.

White already has an advanced changeup, which plays quite well with his fastball, having late dive-and-fade. The pitch features as much as 30 inches of vertical drop and consistently 15 inches of fade, making it a firm plus pitch, sitting around 86 mph.

The sweeper is White’s go-to swing-and-miss pitch, sitting between 78 and 83 mph with a ton of vertical movement plus sweeping action.

White has all the upside in the world, but has been limited at times by command and control. The strike rate of 61 percent is slightly below average, but not in a dangerous range. The future upside in the Majors will hinge on how many batters he walks.
