Arm Speed
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.
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.

Physical: 5-foot-8, 138 pounds; Average, slender build. 9.01 runner in the 60.
Offensively: RHH. Even setup, with feet just outside his shoulders; flat bat to start. Drops hands on the way back with an up and down stride for timing. Stays behind the ball while showing an average effort from the legs. Showed a compact swing path with a late one hand finish. More line drives than flyballs and groundballs with a peak exit velocity of 73 MPH via Trackman.
Defensively: Starts with a low to the ground setup; uses prep hop while showing active feet. Hands are out in front with a clean transfer. Moderate arm circle from a standard 3/4 arm slot. INF - 72 MPH.
Pitching: Uses an arm side setup while using a side step. Mid chest leg drive with a slight lean over the belt. Has a moderate stride landing inline with the plate. Moderate arm swing while arm stays in line with 2B; standard 3/4 slot. Spins off 1B side with finish. FB: Peak velo of 72 MPH, while sitting 69-71 MPH; arm side run with sink. CB: 57-59 MPH; slurve like action. SL: 60-61 MPH; tilting break. CH: 62-63 MPH; fading action.
Physical: Young, stocky frame at 5-foot-7, 138lbs. 9.20 runner in the 60-yard dash.
Offensively: RHH. Upright, slightly open stance, as the hands work flat over the shoulder. Utilized a simple leg-hang stride to initiate the swing through a direct path towards a lifted finish. Featured an adequate feel for the barrel (54%), staying inside the ball for a T82 mph exit velocity via Trackman. Mostly pull-side approach that yielded occasional backspin to the middle of the field.
Defensively: The middle infielder showed a hop in the prep-step and positioned the body from right-to-left at the touch. Fielded off the center of his body using regular posture and delivered an accurate 67 mph arm-strength across the dirt (H ¾).
Pitching: RHP. Middle of the rubber setup; compact, balanced delivery with ability to hold the line. Strike-thrower pounded the arm-side at 65-67 mph (1562), mixing a developing upper-50’s CB and faded 61-62 mph CH.
