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.

Verbally committed to Missouri Southern.
Positional Profile: RHP/1B
Body: 6-0, 207.2-pounds.
Delivery: Easy mover, medium leg lift, tall/fall down the mound, foot lands in-line.
Arm Action: RH. Long, clean arm path, quickness out front, 3/4 slot.
FB: T84, 80-83 mph. Clean out of the hand with some carry T2343, 2113 average rpm.
CB: 67-71 mph. 11/5 shape, can land at times. T2298, 2097 average rpm.
CH: 73-75 mph. Kills spin, plays with fade. T1481, 1446 average rpm.
RHP Mason Leske (Huntley, 2025) was yet another member of the junior class that showed well over the weekend. He has some strength throughout his 6-foot-1, 190-pound frame with round shoulders and evenly proportioned weight. He uses his lower-half well down the mound, sinking into his backside and riding it downhill with a balanced and repeatable operation. His arm plays clean and uninterrupted into a high ¾ release, creating a fastball that sat in the 83-86 mph range (2200-2300+ RPM) with mostly straight action and occasional ride through the zone. To pair off the fastball he went to an 11/5 curveball with sweeping action and occasional depth, maintaining fastball arm-speed and delivering the offering at 67-68 mph. He also displayed a changeup in the 74-76 mph range, thrown with intent while playing with late sink/diving action and above-average feel.
Positional Profile: RHP/1B
