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
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

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.
Deception
The amount of time that the ball is visible to the hitter, after the instant of front foot strike. Measures in milliseconds.
Hip-Shoulder Separation
The difference in angle of between the hips and shoulders, occurring close to the foot plant. Measured in degrees.

Grip Strgth (LH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Grip Strgth (RH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Physical: Long, projectable 6-foot-4, 165lb frame. 7.71 runner in the 60-yard dash.
Offensively: RHH. Balanced, slightly open stance, as the hands operate loose over the shoulder. Utilized a stretched toe-tap stride to initiate the swing through a flat, on-plane path into the hitting zone. Worked inside-out at times, staying short to the ball for a T83 mph exit velocity via Trackman. Maintained some simple barrel-awareness and recorded a 50% line-drive rate.
Defensively: The first baseman featured a spread ready position that sat down at the touch with a soft glove-hand. Fielded off the middle of his body and released quickly, up to 76 mph from a ¾ slot. Covered ground laterally to both sides.
Pitching: RHP. Begins from the middle of the rubber; consistent, leveraged pace with finishing ability. The arm works out a lengthy, full range-of-motion on an upper-70’s, T79 mph FB. Threw strikes often, commanding a sweeping 65-66 mph CB, and killed 70-71 mph CH (1598). Much more to come.
