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.

True Sophomore. The 5-foot-10, 162-pound right-hander is an athletic mover down the mound, working with an up-tempo pace and some swagger in his mound presence. His fastball sat in the 81-83 mph range and reached a max IVB of 18.4. He flashed three quality off-speed offerings, the first being a sharp 11/5 downer curveball at 71-72 mph. His slider plays off an 11/5 plane as well, flashing depth and sitting around 73-74 mph, occasionally backing up on him. His final offering was a changeup at 73-75 mph, thrown with intent and diving late at times under the zone.

Arm: RH. OF - 78 mph. Long, loose arm action, 3/4 slot.
Defense: Sits back on the baseball at times, clean release.
Run: 7.43 runner in the 60.
Positional Profile: RHP/OF
