Position: RHP
Body: 6-4, 170lbs. Long limbs, lanky build has started to fill out over the summer. Substantial projection remaining as he continues his physical development.
Mechanics/Delivery: Small rocker step to an athletic balance point above the belt. Slight turn at the top. Swings the front leg down and out with a deep stabbing take away. Full arm action to an OTT slot. Gains ground with good extension out front. Lands square, on his line. Moderate effort in his delivery. Repeats well.
FB: FB showed life out of the hand working up to 87 mph. Ranging 83-86 mph. Slight running action. Good location in the zone.
SL: True slider at 77-81 mph. Side to side action with late break. Occasional two-tier plane.
CB: 74-76 mph with larger break and downer action.
CH: 77-78 mph. Feels the pitch in the zone with fade to the arm side.
Summary: Projectable RHP with tons of upside. Shows feel for a mix of pitches. FB/SL combo was his best compliment at the T.P.G. Velo has climbed and should continue to do so. Starter/Long Relief profile moving forward.
Physical Profile/Body - 6-4, 165lbs. Slender build with lengthy limbs. High upside.
Mechanics/Delivery - Small rocker step and controlled balance point at the belt. Slight rotation with the hips at the balance point. Deep take away from hand break and full arm arc on the back side. Loads the scaps and works through a H3Q to OTT arm slot. Foot lands square with good extension down the mound.
FB - Showed a 4-seam variation that was primarily straight with good control, pitch topped at 84 and ranged from 82-83 mph. He also showed a 2-seam variation that had heavy tendencies and showed some ASR. Pitch topped at 83 and ranged from 81-82.
SL - Showed a side to side slider at 75 mph. Pitch worked with cutter shape. Flashed potential, showed late bite at times. Lost several pitches up in the zone.
CB - Showed a bigger downer curve at 72-73 mph. Pitch had 11/5 shape and was controlled in the zone.
CH - Pitch showed heavy fade to the arm side at 75-76 mph.
Summary- Repeated the delivery well for a player with his height and length. Showed the ability to mix multiple offerings from similar arm slots. SL has potential to be a quality pitch as he continues to develop it. Showed good control of the lower half of the zone. FB velo will make a jump at some point.
