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+

CH: 72-77 mph. Maintains arm speed well; firm, fading action. T1588, 1485 average rpm.
Positional Profile: LHP/OF
Body: 6-3, 185-pounds. Lean, athletic build, round shoulders.
Delivery: Slight cross body, deceptive delivery, medium leg lift into a coiled balance, drop/drive.

An upside arm worth mentioning is LHP Danny Kienzle (Lyons Township, 2025). The 6-foot-3, 180-pound southpaw has a lean/athletic build, still showing room for added strength in the coming years. He worked his fastball up to 79 mph, sitting mostly 75-78 mph with heavy arm-side life and a max IVB of 16.8. He showed some feel for both his curveball and changeup; with the curveball coming in off a 1/7 plane at 59-60 mph and the changeup sitting 69-71 mph with slight fading action. His final offering was a slider at 63-64 mph which played with up to 14.5” of sweep.
