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: SS/RHP
Body: 5-10, 159-pounds.
Delivery: Sets near center of the rubber, working from the abbreviated wind. Hands set at belt with body turned toward 3B. Simple, repeatable wind as hands raise. Sinks into legs through extension and land. Carries body toward 1B with rear leg dragging through post-release.
Arm Action: RH. Quick arm action after hands break at the letters. Low break into high 3/4 slot release with some shoulder tilt.
FB: T80, 78-79 mph. T1759, 1692 average rpm.
CB: 66-68 mph. T2056, 2000 average rpm.
SL: 70-72 mph. T1886, 1877 average rpm.
CH: 69-71 mph. T1501, 1421 average rpm.
ATH: 7.13 runner in the 60. 1.68 and 3.97 in the 10 and 30 yard splits. 23.90 max vertical.
Positional Profile: SS/RHP
Body: 5-10, 159-pounds.
Hit: RHH. Balanced lower half in stance with weight evenly distributed. Hands quiet with barrel resting on rear shoulder in stance. Hands lower and retract gradually in sync with stride. Twitchy mover through the zone with an uphill barrel path. Wrists turn over with a firm front side at contact and a flatter two-handed finish. 63.3 mph bat speed with 10 G's of rotational acceleration.
Power: 91 max exit velocity, averaged 81.3 mph. 350' max distance.
Arm: RH. INF-81 mph. Quicker arm with high 3/4 slot throws.
Defense: Sinks deeper into lower half with narrow base in prep step. Works to position body around and through ground balls at him to have momentum through throws. Soft hands funnel ball to belt before release. Middle INF actions.
ATH: 7.13 runner in the 60. 1.68 and 3.97 in the 10 and 30 yard splits. 23.90 max vertical.
