Positional Profile: RHP/SS
Body: 5-11, 170-pounds. Donaldson, a 5-foot-11, 170-pound right-hander, works his fastball in the 82–84 mph range and has touched 85, spinning it in the 2270–2360 RPM window with solid ride (12.5 IVB) and arm-side action (6.2 HM). His best secondary is a 72–74 mph slider with tight spin that jumps into the 2600–2800 RPM range, showing late bite and swing-and-miss potential. He rounds out the arsenal with a developing changeup at 70 mph, flashing some arm-side fade. With three pitches, advanced slider metrics, and competitive mound presence, Donaldson profiles as an arm to follow closely in the 2026 class.
