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.

Mason Hamlett: RHP, (2026) South Dearborn High School, IN. 6-foot-2, 190-pound. (63.1 mph bat speed average). (20.3 mph hand speed average). Begins in a balanced quiet stance with a compact load, then uses a controlled stride. Bat speed was efficient, had a simple flat swing plane and high finish. Solid in the infield, recorded a position velocity of 78 mph; had sure hands, consistent footwork, and a natural exchange. Movements laterally were athletic and he fields the ball out front. Used a high ¾ slot and a quick arm action. On the mound, showing some arm speed he had a quick arm action with a high ¾ arm angle. Drop-and-drive type pitcher and uses some effort. (Max spin 2263; Avg 2129).
