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.

Jacob Erb, Homestead Senior High School (IN), 2026
Positional Profile: LHP/1B
Body: 6-2, 195-pounds. Athletic, projectable frame. Still has room to fill out more.
Delivery: Moderate tempo delivery with a slightly high leg kick but comfortable balance point. Does not get much distance down the mound as hips stay compact and relatively closed. Shoulders remian even and compact down the slope. Consistent mechanics, stays tall throughout delivery. Lands square on ball of foot rather than heel.
Arm Action: LH. Quick, compact arm action from an over the top slot.
FB: T81, 77-80 mph. Ride and run. T1922, 1869 average rpm.
CB: 63-67 mph. Slider T2025, 1874 average rpm.
CH: 64-67 mph. Run over ride with efficient movement. T1555, 1502 average rpm.
