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 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: 1B/RHP 1B with smooth LHH power stroke.
Body: 6-1, 219-pounds. Sturdy, well-proportioned build.
Hit: LHH. Starts from an upright, balanced stance that begins slightly open. Hands set behind the ear with the barrel flat across the shoulder and minimal pre-pitch hand movement. Initiates load by shifting weight onto the back side as the hands drift back and the barrel works vertically. Employs a small leg lift for timing, leading into a controlled stride forward with length, landing even. Aggressive hip fire at foot strike, paired with an explosive upper half. Hands work quick through the zone with present bat speed. Uphill path produces consistent carry up the middle, showing gap-to-gap power. 71 mph bat speed with 20 G's of rotational acceleration.
Power: 99 max exit velocity, averaged 79.8 mph. 296' max distance.
Arm: RH. INF-78 mph. Short, compact arm path with a very low 3/4 release. Throws with accuracy across the infield and profiles to stick at first base.
Defense: Gets low pre-pitch with hands that stay low, working into a clean two-handed gather. Lets the ball travel into his frame while displaying direct, compact footwork that can display intent when working downhill. Profiles well at 1B.
ATH: 7.31 runner in the 60. 1.62 in the 10 yard split. 18.80 max vertical.
Vizual Edge: 68.87 Edge Score
Positional Profile: 1B/RHP
Body: 6-0, 212-pounds. Strong and athletic with good proportions.
Delivery: Slight bend in back knee, starts by stepping off to side, quick leg lift, steady head.
Arm Action: RH. Long action, full extension in back swing, 3/4 slot, displays some whip.
FB: T82, 78-81 mph. Accurate with late life. T1979, 1899 average rpm.
SL: 67-69 mph. Displays feel for pitch, gradual break. T1849, 1785 average rpm.
SPLT: 68-71 mph. Deceptive with vertical drop.
ATH: 7.44 runner in the 60. 1.78 and 4.06 in the 10 and 30 yard splits. 17.60 max vertical.
Positional Profile: 1B/RHP
Body: 6-0, 212-pounds. Strong and athletic with good proportions.
Hit: LHH. Wide in the back of the box, weight shifted on back leg, toe tap stride. Quick hands with a heavy barrel, explosive. 70.6 mph bat speed with 16 G's of rotational acceleration.
Power: 97 max exit velocity, averaged 87.7 mph. 366' max distance.
Arm: RH. INF-68 mph. Longer with full extension, 3/4 slot.
Defense: Soft two-hand gather out front.
ATH: 7.44 runner in the 60. 1.78 and 4.06 in the 10 and 30 yard splits. 17.60 max vertical.
Vizual Edge: 58.39 Edge Score
