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.

RFr. RHP Mason Lechowicz (Crystal Lake Central, IL) worked a four-pitch mix throughout his ‘pen. 6-foot-2, 190-pounds, evenly proportioned strength with long legs. Athletic mover with a quick arm out front, fastball sat around 85-86 mph, topping at 87 mph with over 2,300 rpm on occasion, mostly straight action. Slider is thrown with intent at 76-77 mph, quality 10/4 shape with some depth (+2300 rpm). He also went to a cutter in the 77-79 mph range, playing with shorter action than the slider, late break off a lateral plane (+2400 rpm). His final offering was a changeup in the 75-77 mph range, killing spin and running to his arm-side a bit.
Positional Profile: RHP/1B
Body: 6-1, 178-pounds. Proportional strength in upside frame.
Defense: Careful gather, demonstrated some body control.
Arm: RH. INF - 74 mph. Short arm action from a high 3/4 slot.
Hit: RHH. Wide/balanced base, hands set out. Subtle load back into deep arm bar. Bat path is long to the zone, long and level through the zone. Generates above-average bat speed, average of 72.4 mph, per Blast.
Power: 82 mph exit velocity from the tee. Above-average bat strength for age; max exit speed of 91.2 mph, max distance of 334 feet.
Run: 7.78 runner in the 60.
Delivery: Side step rock to balance point, shoulders uphill, hip turn. High front side, hips open early, leading to open landing.
Arm Action: RH. Short arm action to a 3/4 slot.
FB: T77, 75-76 mph. Mostly straight, some arm-side run.
CB: 57-59 mph. Early break, gradual 11/5 action; some feel for spin.
CUT: 62-65 mph. Some short cut action.
