Tucker Wollesen, Keller (TX), 2027
Positional Profile: RHP RHP…Arm works with developing arm speed, opportunities for adjustments with delivery. Look for FB velo to increase with added strength and physical maturity, delivery adjustments. Slider flashes spin, looking for consistency to release point for spin, effective when landed. Knuckle shows some down action. Lands split showing developing depth to pitch.
Body: 6-0, 183-pounds. Good physical build to add strength in future.
Delivery: Side step rocker, high knee lift. Gets to post up, stand tall and fall delivery. Stride foot lands beyond midline, opens hip and front shoulder early. Solid finish. Opportunities to firm delivery and add to efficiency.
Arm Action: RH. Compact/cutoff circle. HTQ slot, good finish out front. Arm speed developing.
FB: T81, 78-80 mph. Around zone with FB, shows carry to FB up. Arm side tail present. T1908, 1844 average rpm.
SL: 68-71 mph. Short breaker showing some depth. Inconsistent showing spin, when he lands spin, solid pitch. T1926, 1595 average rpm.
KN: 72-73 mph. Developing pitch, shows some sink.
SPLT: 71-73 mph. Sink present, shows feel for pitch and ability to land in zone.
ATH: 7.31 runner in the 60. Runs hard, solid form, will improve with strength and maturity.
