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.
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.

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: LHP/1B Solid tools/ability for 2027 grad. Will gain strength, development opportunities present with adjustments. Like future bat/power combo. LHP…Arm works with opportunities to firm delivery. Expect velo to increase with added strength. Flashes feel for CB/Slider action. Developing arm with time to improve.
Body: 5-7, 168-pounds. Solid build/frame to add strength in future. Some thickness/strength to lower now.
Delivery: Simple delivery with online stride. Can improve lower 1/2 use, lacks solid push off back leg. Finish direction can be improved.
Arm Action: LH. Full circle, works fine, fair extension out front, developing arm speed.
FB: T74, 69-73 mph. Looking for velo spike in future. Shows nice plane when down in zone. T1800, 1669 average rpm.
CB: 62-65 mph. Soft, early action. Will firm as arm speed increases. T1606, 1486 average rpm.
SL: 66-68 mph. Short breaker, shows limited depth. T1616, 1612 average rpm.
ATH: 8.11 runner in the 60. Runs hard. 22.90 max vertical.
Positional Profile: LHP/1B Solid tools/ability for 2027 grad. Will gain strength, development opportunities present with adjustments. Like future bat/power combo. LHP…Arm works with opportunities to firm delivery. Expect velo to increase with added strength. Flashes feel for CB/Slider action. Developing arm with time to improve.
Body: 5-7, 168-pounds. Solid build/frame to add strength in future. Some thickness/strength to lower now.
Hit: LHH. Open stance start, knee lift stride, landing straight away in good position to hit. Rotational back foot, some linear movement to back foot, can drive back foot forward more…improving use of back hip/lower 1/2. Would suggest trying to firm linear movement forward with back foot increasing drive of lower 1/2. Hits off firm front side with body in good position. Hands/barrels start in solid position, some length to swing, would love too see more direct path to zone with hands/barrel. Presently, initial movement is hands work away from body instead of taking know towards home plane. Really good swing components with opportunity to improve. Bat/hand speed will improve with added strength. 65 mph bat speed with 13 G's of rotational acceleration.
Power: 91 max exit velocity, averaged 82.4 mph. 287' max distance. Solid bat/power combo in future, raw power will continue to improve with added strength and hit approach opportunities.
Arm: LH. INF-70 mph. Arm work fine, fair arm speed, accuracy to throws present. Would benefit from long toss program. Will improve.
Defense: Moves to bag fine with footwork. Nice job of getting into fielding position with feet. Fields baseball deep, can improve fielding out front. Avg body control/agility.
ATH: 8.11 runner in the 60. Runs hard. 22.90 max vertical.
