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.

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.
Positional Profile: OF/SS
Body: 5-10, 160-pounds. Lean, athletic build.
Delivery: Stretch primary delivery with a quick, compact leg lift keeping the weight comfortably held low in drive hip. Stride achieves sufficient distance down the mound with some separation. Upper half works relatively even down the slope with separation. Majority of velocity comes from strong back hip rotational acceleration. Whippy overall delivery with abv/avg torque.
Arm Action: RH. Longer, loose arm action from an over tghe top slot.
FB: T84, 79-83 mph. Straight FB on y-axis. (+) spin. T2265, 2101 average rpm.
CB: 63-66 mph. Big, gradual glove side sweep and drop. (+) spin. T2238, 2110 average rpm.
SL: 68-69 mph. Wipeout movement profile with (++) glove side sweep on an even plane. Will tunnel well with CB. T2061, 1892 average rpm.
CH: 67-69 mph. Straight fading CH. Developed movement profile. T1586, 1531 average rpm.
ATH: 6.99 runner in the 60.
Positional Profile: OF/SS
Body: 5-10, 160-pounds. Lean, athletic build.
Hit: RHH. Athletic setup, kickstand on front foot. Compact upper body load, big leg kick stride - impressive body control for bigger moves. Barrel works uphill with significant bat speed for the age. More of a pull-side approach, will grow into real juice.
Power: 94 max exit velocity, averaged 85.7 mph. 361' max distance.
Arm: RH. INF-78 mph. OF-89 mph. Loose, quick arm action from an over the top slot.
Defense: (INF) Smooth footwork with obvious confidence in the glove. Strong ball to hand skills. (OF) Swift mover with an athletic shuffle crow hop in delivery. Shows ability to get around and behind the ball with ease. Comfort with glove. Easy exchange.
ATH: 6.99 runner in the 60.
Positional Profile: OF/RHP
Body: 5-10, 160-pounds. Lean, athletic build
Hit: RHH. Athletic stance, starts slightly open. Stays behind the ball within a leg kick stride, hands load up w/ tall back elbow. Turns the barrel on-plane deep, works uphill, with advanced bat speed / strength for the class. One of the more advanced '28 bats we've seen thus far.
Power: 93 max exit velocity, averaged 88.0 mph. 348' max distance.
Arm: RH. OF-88 mph. Loose, athletic arm action w/ advanced arm speed
Defense: Athletic mover, works downhill with soft, confident hands. Twitchy exchange
ATH: 6.97 runner in the 60.
