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

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/3B
Body: 5-11, 164-pounds. Leaner and athletic body, more room to add mass and size. Lots of twitch and quick mover.
Delivery: Easy and compact delivery with minimal extra movements. Strides down decently but could even sit longer in his bacskside before internally rotating the back hip into firing position. Low and hindged leg lift with simple push-off into hand seperation.

CB: 71-73 mph. CB showed true spin ability in the 2600 RPM range with snap to it. Breaks late with potential to be a really good offering. Got multiple swing and misses during early counts and was able to work it down and off the plate with two strikes for bad swings. Really strong feel for this pitch and its abilty to create depth while tunneling it off FB. Hard to pick up out of hand. T2644, 2507 average rpm.
ATH: 6.82 runner in the 60. 1.67 and 3.81 in the 10 and 30 yard splits. 36.20 max vertical.
