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

LHP Chandler Alderman (North Boone): Yet another high-follow uncommitted left-handed arm who made a strong impression on Sunday. Alderman, also a quarterback on the football team, sports a wide-shouldered, athletic, 6-foot-3, 190-pound frame and controls his body well, given his age and frame. The arm and delivery work clean and he consistently worked his low-80’s fastball (up from 76-78 mph this fall) down in the zone with tilt and an average spin rate of 2246 rpm. He also showed feel for his entire arsenal, including a curveball and slider that played in the low-to-mid 70’s with tight spin (2341 rpm average for both).
6-foot-4, 190-pound, strong-bodied, physically-advanced, left-handed pitcher. Started on the mound for Pro Player on Sunday. Methodical, controlled delivery, repeated well for his age and size. Controls his body, works downhill and threw a high-volume of strikes throughout his start. Fastball works straight, showed control, creates angle, sat 76-78 mph. Best secondary looks to be a tight slider thrown at 71 mph. Thrown with arm speed, confidence and feel; short wrinkle, tunnels off fastball, 1/7 shape. Follow 2023 left-handed pitcher in the Illinois’ 2023 class.
