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.

Will Gnirk, Chaparral (AZ), 2027
Positional Profile: LHP/OF
Body: 6-3, 176-pounds. Tall, lean frame with good athletic projection and ample room to add strength as he matures.
Delivery: Short, compact delivery that stays tall while sitting decently into the backside. Works with a big stride toward home, keeping his line and showing a repeatable motion.
Arm Action: LH. Long, loose arm with whippy action and healthy deceleration. Works from a high three-quarter slot, though misses tend to stay up when the ball is released early.
FB: T86, 83-86 mph. Low-to-mid 80s with heavy sink and strong arm-side run, giving it a natural groundball profile. Around the zone enough to compete, and projects well when working to the lower half. T2288, 2130 average rpm.
SL: 77-78 mph. Upper-70s with elite spin and sharp break, showing both depth and sweep. Tight, late action gives it swing and miss potential and projects as a true out pitch with continued development. T2695, 2654 average rpm.
CH: 79-80 mph. Upper-70s to 80 mph with significant arm side fade and limited depth, playing more as a running changeup. Lower spin helps create separation from the fastball, projecting well as feel sharpens. T1624, 1576 average rpm.
ATH: 21.50 max vertical.
