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.
Body: 5-8, 145-pounds. Short athletic frame with room for added size and strength.
Delivery: High leg kick to a balanced slope descent, gets good extension for size/age, rotates around leg block, follows through with conviction.
Arm Action: RH. ¾’s arm slot, lengthy to start, but tightens up as the arm moves forward, slight hitch as it does.
FB: T76.5, 75-76 mph. High vertical break on the fastball, displays some command. T1960, 1892 average rpm.
CB: 63-65 mph. Both breaking balls are difficult to distinguish, but it’s less of an issue because both profile with high movement and good deception. Solid intent and use of the pitch. T2268, 2189 average rpm.
SL: 65-66 mph. T2209, 2166 average rpm.
CH: 70-70 mph. Intent is good on the change-up, tends to miss arm side, but able to effectively kill speed and spin. T1331, 1288 average rpm.
