Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average

Grip Strgth (LH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Grip Strgth (RH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Positional Profile: RHP/RHP RHS with solid build to add strength in future. Repeats delivery and arm action. Cross step delivery, HTQ slot with arm working around body. Looking to see some spike in velocity in future. CB/SL blended action, sweep/slurvy type. DNS change this outing. Nice upside, around the with stuff.
Body: 5-11, 194-pounds. Good frame/build to add strength in future. Width to back and shoulders.
Delivery: Knee lift with slight inward turn. Floats thru balance point, stride leg kicks out, then works down slope. Middle rubber start with cross step delivery. Works around body.
Arm Action: RH. Full circle, 3/4 slot, around work somewhat around body, fair extension to release point. Good deceleration to arm.
FB: T86, 84-86 mph. FB shows developing ability to work in/out. Shows some tailing action, increasing to arm side. Around zone, expect FB velocity to tick up in future. T2118, 2012 average rpm.
CB: 70-71 mph. Blended breaking ball, nice spin to pitch, sweep/slurvy type action. Would like to ability to get more on top of pitch creating some depth to action. Action fits with arm working around body in delivery. T2066, 2028 average rpm.
SL: 72-74 mph. Blended breaking ball…action is similar to CB description. T2074, 1989 average rpm.
