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

8/10/25
5-foot-10, 175-pound proportional frame with present strength. LHH with a smooth, controlled swing that produces consistent hard contact; 98 mph max exit velocity with a 295’ peak distance shows gap-to-gap pop with emerging over-the-fence power. Stays on-plane with the barrel, working through the middle of the field with balance. Defensively, shows solid actions at 3B with an 83 mph arm across the infield. On the mound, works from a clean RH delivery; FB at 81-83 mph (T83) with up to 2,148 rpm, complemented by a 71-73 mph CB (T2159) and an 80-81 mph CH. Athletic mover with a 7.15 60-yard dash and quick splits (1.72 / 4.00). Bat-first profile with two-way value and the potential for impact offensive production at the next level.
