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
Slider
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Slider
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Daniel Seymour: SS/RHP, (2025) Rochester Adams, MI. 6-foot-1, 175-pound proportional lanky build. (72.7 mph bat speed average). (21.9 mph hand speed average). Began in a balanced open stance with a smooth compact load, then used a long closed stride. Bat speed was electric explosive, used a simple long swing plane and level finish. He barreled up lots of balls with a lot of loud contact. Up the middle gap to gap approach. While in the infield, made throws at velocities up to 82 mph. Behind the plate, has a quick clean transfer, athletic smooth feet, and soft consistent hands. Used a high ¾ slot and a short arm action while showing consistent accuracy to the bag. Smooth solid on the mound, showed quick arm speed with a ¾ arm angle and a short arm action. Tall-and-fall type pitcher who uses easy effort. Shows downhill shoulders. Lands closed with an athletic finish. Threw his fastball 78-80 mph and topped out at 81 mph; showed running action and arm side control with tight movement. (Max spin 2163; Avg 2000).
