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
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ 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/OF Long levered frame, with ability to add more weight and muscle. Curveball spins well and will be interesting to see progression as body matures.
Body: 6-2, 170-pounds. Tall and lengthy frame, with weight and muscle to add on.
Delivery: Worked exclusively out of the stretch, small leg lift with front leg coming around to create lag. Front side stays firm through delivery.
Arm Action: RH. OTT arm slot with high release point, takeback is long and comes behind body.
FB: T77, 75-77 mph. Works well to top of the zone, with some ride. T1877, 1774 average rpm.
CB: 62-63 mph. Shows shape and works truly at 12/6. Spins tight when released out front and with present arm slot is deceptive. T1859, 1837 average rpm.
CH: 69-71 mph. Arm side run, and velocity change shows seperation from fastball. T1789, 1725 average rpm.
