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

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.
Positional Profile: OF/RHP Two-way athlete with strength and competitiveness on the mound a swing built for steady line-drive production.
Body: 5-8, 187-pounds. Compact, strong frame with solid muscle development. Lower half strength is trending upward, aiding both power and overall stability.
Delivery: Works strictly out of the stretch, giving him a simple, repeatable operation. Starts tall, then drives into a high leg lift that brings the knee near the chest. Holds his glove firm at the sternum, maintaining composure throughout. Stays centered over the rubber and moves into a clean line toward the plate with balanced intent.
Arm Action: RH. Shows a classic over-the-top arm stroke with full extension away from the body before accelerating down the mound.
FB: T83, 78-82 mph. Mix of subtle ride and late arm-side action. Stays true in the zone and plays up when elevated. T1926, 1811 average rpm.
SL: 71-74 mph. Works off a sweeping shape that changes the hitter’s eye level. Effective as an early-count strike or off-speed look. T1971, 1738 average rpm.
CH: 72-72 mph. Arm-side fade with a subtle tumble at the end. Lower spin helps it create contrast off the FB despite similar arm speed. T1358, 1358 average rpm.
ATH: 7.58 runner in the 60. 1.75 and 4.18 in the 10 and 30 yard splits. 20.60 max vertical.
Positional Profile: OF/RHP Two-way athlete with strength and competitiveness on the mound a swing built for steady line-drive production.
Body: 5-8, 187-pounds. Compact, strong frame with solid muscle development. Lower half strength is trending upward, aiding both power and overall stability.
Hit: LHH. Begins from a relaxed, slightly open posture with weight leaning toward the back side. Hands sit comfortably above shoulder height before working into a deeper stretch during the load. Uses a controlled leg lift to sync the upper and lower half. Creates a tight, direct path to the ball with a swing geared toward firm contact to the pull side and middle. Shows feel for keeping the barrel on plane for a long time. 57.8 mph bat speed with 20 G’s of rotational acceleration. 61.2 mph bat speed with 24 G's of rotational acceleration.
Power: 89 max exit velocity, averaged 72.2 mph. 321' max distance.
Arm: RH. OF-82 mph. Over-the-top release gives the ball natural carry. Arm works with length on the backside and cleans up well through release. Throws stay online with more strength likely on the way.
Defense: Controlled mover who keeps his body under control through the play. Takes measured routes, fields the ball with steady tempo, and transitions cleanly into his throwing motion.
ATH: 7.58 runner in the 60. 1.75 and 4.18 in the 10 and 30 yard splits. 20.60 max vertical.

Positional Profile: OF/RHP Two-way prospect with a sturdy frame. Left-handed bat showing rhythm and consistent line-drive contact.
Body: 5-9, 182-pounds. Shows strength throughout the frame with continued physical development coming in the lower half.
Delivery: Works exclusively from the stretch, using a high leg lift that brings the knee to the chest while keeping the glove firm at chest height throughout the delivery.
Arm Action: RH. High over-the-top release, extending fully on the backside before driving forward through release.
FB: T82, 77-80 mph. FB with balanced ride and run. The late arm side movement adds deception against LHH hitters T2001, 1864 average rpm.
SL: 70-72 mph. Short SL with modest glove-side movement and some depth. Lower spin gives it more sweep/tilt over pure bite. Works as a change-of-pace pitch off the FB. T2052, 1809 average rpm.
CH: 71-73 mph. Fading CH with lower spin that allows it to separate from the FB while maintaining deceptive movement. Best used to disrupt timing against LHHs. T1882, 1680 average rpm.
ATH: 7.62 runner in the 60. 1.80 and 4.18 in the 10 and 30 yard splits. 21.50 max vertical.
