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.
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

Avery Siperke: RHP/3B, (2024) Kenston, OH. 6-foot-1, 185-pound. Solid on the mound, used a clean arm action and a high ¾ arm angle while showing consistent arm speed. Feel type pitcher and uses some effort. He has downhill shoulders and a strong balance point. Lands soft with balanced finish. Shows slight running action. (Max spin 1986; Avg 1911). His 11/5 curveball has gradual action. (Max spin 1886; Avg 1720).
5-foot-10, 142-pound athletic frame. At the plate, Siperke had a max exit velocity of 81 mph. Setup was comprised of a balanced stance and a compact load. Bat speed is quick and uses a flat swing plane. He found some barrels during his rounds. Gap to gap approach. In the infield, his position velocity was registered at 68 mph; had developing footwork, and a clean exchange. Movements laterally were developing and he fields the ball out front. In the 60-yard dash, his time was 8.38. Smooth on the mound, showed some arm speed, he had a loose arm action and a high ¾ arm angle. Drop-and-drive type pitcher and shows easy effort. Sat with his fastball at 72-74 mph; had running action and command low in the zone. Threw a 11/5 curveball (61-63) with gradual action. His changeup (64-64) has fading action.
