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.

CB: 66-69 mph. 1/7 shape, gradual, feel for pitch. T2448, 2288 average rpm.
CH: 71-75 mph. Late fade to the armside, maintains arm-speed. T1558, 1459 average rpm.
A pair of pitchability southpaws who put together polished ‘pens on Monday: LHP Mason Hartman (Collinsville, IL, 2024) and LHP Ryan Souden (Fredericktown, IL, 2025). Hartman pounded the lower half of the strike zone with a fastball/changeup mix that mirrored each other, and he worked to both corners with consistency from a high arm slot, too. He spun a 2300+ RPM curveball with horizontal spin at 66-68 mph to round out a mix that’ll consistently live in the zone. The same can be said for Souden, who also threw all three of his pitches for strikes. His low-80s fastball favored the arm-side corner of the plate, and he threw both his changeup and curveball in the zone as quality compliments.
