Pitch Scores
2024
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.

Jack Manzella: SS/RHP, (2026) Fraser, MI. 6-foot-1, 165-pound. (68.1 mph bat speed average). (20.0 mph hand speed average). Started in a balanced stance with a smooth load, then used a controlled small leg kick. Bat speed was above average, displayed a short simple swing plane and level finish. Found multiple barrels with some loud contact. Up the middle gap to gap approach. Athletic above average while in the infield, registered his best throw across the diamond at 83 mph; shows a quick fluid exchange, consistent feet, and twitchy sure hands. Fields the ball out front, movements laterally were quick. Solid capable on the mound, showed consistent good arm speed with a short clean arm action and a high ¾ arm angle. Tall-and-fall type pitcher and uses some effort. Tall balance point with in line shoulders. Lands square with a falling off finish. (Max spin 2207; Avg 2094).
