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

Physical: 6-1, 200 pounds; Sturdy, Proportional build.
Pitching: Uses a glove side setup while using a side step. Mid chest leg drive with shoulders outside the hips. 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 87 MPH, while sitting 82-85 MPH; arm side run. SL: 72-74 MPH; 2-tier break. CH: 77 MPH.
Physical: Stocky, durable 6-foot, 200lb frame. 8.39 runner in the 60-yard dash.
Offensively: LHH. Upright, open stance, as the barrel starts from a strong position to hit. Utilized a simple leg-lift stride to initiate the swing through a flat, direct path into the hitting zone towards a two-handed finish. Some rotational parts, but knows how to start/stop the body at the front of the plate. Recorded a T91 mph exit velocity via Trackman with a 56% sweet spot rate during his round, living in the pull-side gap for extra-bases.
Defensively: The third baseman operated from a wider base, shuffling his feet and chopping on the approach with a soft glove-hand. Featured lower-effort throws across the dirt, notching a 74 mph arm-strength on this date.
Pitching: RHP. Starts off the left part of the rubber; smaller rocker step with developing pace into the stack. Repeated the forward move with a hip-hinge, throwing in a quick-window (H ¾ slot). Commanded the FB at 81-85 mph (2179) and added a quality 69-71 mph CB with consistent lateral tilt.
Physical: 5-foot-8, 160 pounds; strong, sturdy. 9.34 runner in the 60. Offensively: LHH. Open, shoulder width, 45 degree; hands short back, exaggerated shift/stride to back side to long even stride. aggressive, strong lower half with long with lift. Strong contact, pull side approach; peak Trackman exit velocity of 83 MPH. Defensively: Upright; lays back. funnels to the hip; moderate arm swing, standard 3/4. INF - 67 MPH. Pitching: Far glove side, slight drop step, simple repeatable. Standard 3/4. FB: T 67MPH, 59-67 MPH. Above average arm side run. CB: 54 MPH. 10-4 rotation with above average horizontal break and good vertical break.
5-foot-7, 160-pound left-handed hitter starts from a square stance and uses a knee-to-knee stride to begin. Gets on plane early and creates routine back spin with a gap-to-gap approach. Registered a bat exit velocity of 72 mph and ran a 9.41 60-yard dash. Showcased capable defensive actions in the infield with developing 70 mph arm strength across the diamond. The righty sat 72-74 on the mound out of a high 3/4 arm slot with a simple, repeatable delivery. Curveball at 61-63 showed late breaking 11/5 action. Changeup at 64-68 was thrown at near fastball arm speed.
