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.

Physical: Lean, high-waisted 5-foot-11, 150lb frame with feel. 7.14 runner in the 60.
Offensively: LHH. Bent, balanced stance, as the hands started free and easy over the shoulder. Utilized a directional lift-and-replace stride to initiate the swing through a flat path with middle of the field extension into the hitting zone. Adjustable approach in the box that matched plane all over for a T86 mph exit velocity. Recorded a comfortable 67% barrel rate and was able to spray line-drives from chalk to chalk.
Defensively: The outfielder begins from a wider base with a quick cross-over step to create range. Worked around the ball using a soft glove-hand outside the left foot to corral, setting up the feet for an 81 mph arm-strength positionally (H ¾ slot, quick release).
Physical: 5-foot-10, 140 pounds; Lean, long build. 7.05 runner in the 60.
Offensively: LHH. Open setup, with feet shoulder width apart; upright bat position. Short take back with the hands with an up and down stride for timing. Stays behind the ball while showing a strong lower half. Showed a direct swing path with a two handed finish. More line drives than flyballs and groundballs with a peak exit velocity of 85 MPH via Trackman.
Defensively: Starts with an upright /tall setup; uses prep hop while displaying fluid actions to the baseball. Hands are off to the side with a seamless transfer. Moderate arm circle from a high 3/4 arm slot. OF - 78 MPH.
Pitching: Uses a glove side setup while using a side step. Belt high leg drive with a slight coil away from the plate. Has a long stride landing inline with the plate. Moderate arm swing while showing some scap load; high 3/4 slot. Recoils with finish. FB: Peak velo of 80 MPH, while sitting 79-80 MPH; arm side run. CB: 60-62 MPH; late action. CH: 73-74 MPH; fading action.
