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.

OF/RHP Jackson Leonard (Eureka, 2028) is quickly emerging as a name-to-know two-way prospect in Missouri’s 2028 class. A physically imposing 6-foot-4, 215-pound athlete, Leonard utilizes his long levers to generate natural leverage and bat speed from the right side. He swings with controlled aggression and intent, consistently looking to lift the baseball to the pull-side throughout his round. Leonard flashed serious juice, squaring up his best ball at 103.2 mph (93.2 mph avg. EV) and sending it 363 feet. On the mound, Leonard offered an equally intriguing look. He’s an athletic mover with projection, filling up the strike zone with a lively fastball that sat 86-89 mph and spun at 2,200+ RPM. He complemented it with a sharp 79-81 mph slider that flashed true swing-and-miss potential, and he also mixed in a developing changeup in the low-80s to round out his arsenal.
