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
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.

Scouting Report: 5-foot-9, 140-pound, thin athletic frame, with room for added weight gains. A right-handed hitter, a taller stance, hands are set higher, bat is tilted and loaded. The stride is longer, quick, could stay back a tick more. The swing is level, approach is to pull side, with a higher finish. The exit velocity was clocked at 86 mph and ran a 7.59 sixty-yard dash. From the outfield, quick prep steps, could lengthen the lead leg longer, to get on time more with arm. The arm action is shorter, with some hook on the bottom of the path, working from a higher slot. Clocked at 76 mph, shows carry and life out of his hand. Off the mound, the delivery is up tempo, lead lands across the body, with the foot being open. The arm action is loose and whippy, working from a 3/4 slot. The fastball was clocked at 75-78 mph, creating a good amount of arm side run with fastball. The breaking ball was clocked at 68-69, with good depth and tilt to it.
Exit Velocity: 86 mph
Arm Velocity: 76 mph
Sixty-Yard Dash: 7.59
