The reactive strength index measurement of an athlete's explosiveness by comparing their jump height to the ground contact time in between their jumps. On a scale of 0-5.

The maximum speed, in the direction of home plate, that the wrist is traveling. Measured in meters per second (m/s)
Arm Slot
Angle of the forearm relative to the ground between maximum external rotation (MER) and ball release (BR). Which can be a powerful player comparison metric, delivered in degrees.
Knee Extension Velo
The angular velocity of the front knee straightening after foot plant, which provides indicators of velocity potential. Measured in degrees per second.

LHP Joshua Holst (Libertyville, 2025) was another arm that should rise considerably up the state rankings. Holst catches your eye immediately with his 6-foot-2, 205-pound, hulking, physical build, which is made even more impressive by the way he moves down the mound. Holst is highly-athletic down the mound working with smooth tempo, staying on-line, repeating and filling up the strike zone with his fastball (80% clip) that sat 85.7-87.8 mph with an average of 16.9 inches of induced vertical break and 13.3 inches of horizontal movement. He complimented the fastball with two above-average offerings in a sweeping slider at 71.6-72.6 mph and a changeup that is thrown with intent and showed above-average feel at the bottom of the zone. Has a chance to be a high-level left-handed arm in the class.

6-foot-2, 190-pounds, big muscular lefty. Clean-up type hitter, slightly open stance, smooth load and weight transfer. Has the ability to use the whole field and adjust to low pitches, is disciplined at the plate. In the semi-final game of the PBR at The Rock Championships, against Hitters, he went 2-for-2 with a walk and two RBI’s. On the mound works out of an over the top slot, long arm action. Fastball plays with feel, mostly straight four seam type, 73-75 mph. Curveball played soft at 55-57 mph, with depth and landed for strikes.
6/02/20
Long and lean frame at 6-foot, 175-pounds. Left-handed pitcher, clean, easy delivery. Low effort on a 67-69 mph fastball, comes out of the hand clean and with ease, ability to control with makings of late finish. Changeup played 62-63 mph, fade action. Showed curveball at 52 mph, 1/7 shape, some depth.
