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 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 Two-way player with an interesting 4-pitch mix and defensive upside at 1B.
Body: 5-9, 160-pounds. Well-balanced build with proportional frame.
Delivery: Repeatable windup that utilizes a large leg kick up to the chest. Slight sink into the back hip and inward rotation.
Arm Action: LH. Hands break high and utilizes a downward reach into a short arm motion that finishes over the top. Arm action is repreatable and consistent.
FB: T79, 78-79 mph. Present command to both sides of the plate but better control to the armside. Slight arm side run. T1931, 1855 average rpm.
CB: 64-67 mph. Soft CB with early break. Mimics a slurve profile with noticeable vertical break and slight horizontal break. T1795, 1780 average rpm.
SL: 68-68 mph. Glove-side sweep with subtle vertical break. T1988, 1898 average rpm.
CH: 74-75 mph. Sinker like CH that mimics arm side run of FB. Slight arm side fade. T1616, 1548 average rpm.
Positional Profile: LHP/1B Two-way player with an interesting 4-pitch mix and defensive upside at 1B.
Body: 5-9, 160-pounds. Well-balanced build with proportional frame.
Hit: RHH. Narrow, open and balanced stance with neutral hands. Rocks backward to initiate heavy forward stride. Hands move backwards during stride to create tension. Quick, level swing with minimal extension. Looks for the ball to get deep. 66.7 mph bat speed with 16 G's of rotational acceleration.
Power: 89 max exit velocity, averaged 72.3 mph. 289' max distance.
Arm: LH. INF-80 mph. Quick, short arm action that finishes over the top. Ball leaves the hand with noticeable speed.
Defense: Works out of a strong base and works around the baseball. Quick, snappy hands allow for last second adjustments. Utilizes good direction when throwing to bags.
