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
Slider
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Slider
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Body: 6-3, 190-pounds. Large frame, room to put on lean mass.
Delivery: Mature feel, repeatable in the windup and stretch, sits in back leg and lands upright, balanced head.
Arm Action: RH. Short arm swing, no stress arm action, high 3/4 arm slot, more in the tank, let it rip and follow through.
FB: T78, 77-78 mph. Fastball shows extreme ride with a 21.6 IVB average and low run with a 3.0 HB average. 12:15 tilt shows his high release point and that his fastball will play up-and-down.
SL: 70-71 mph. Slider acted more like a cutter with 12:45 tilt, 2.7 IVB and -0.4 HB. Arm slot works for 12/6 type curveball and would benefit the current slider/cutter combination.
CH: 73-75 mph. Best current offspeed offering. Mimicked fastball with 20.5 IVB average and showed slight run with a 7.1 HB average. Run and speed differential give it a power change feel and show potential for swing and miss now and down the line.
