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

Physical: Highly projectable 6-foot-6, 185lb frame. 8.07 runner in the 60-yard dash.
Offensively: RHH. Spread, slightly bent stance, as the hands operated calmly to begin. Utilized a toe-tap stride to initiate the swing through a flat, whippy path with some directional parts. Worked towards a soft front side, allowing for a middle of the field approach during BP. Recorded a T88 mph exit velocity and 261 foot distance, leveraged off the front of the plate.
Defensively: The outfielder moved well in space for size, chopping the feet around the ball with a bent back at the fielding window. Gathered off his left and delivered an accurate, carrying throw up to 82 mph positionally (H ¾). Corner OF skill set.
Pitching: RHP. Stretch-only from the left corner of the rubber; comes set with some crossfire. Hides the rear-hip with quality movements down the slope. Clean extension on an 83-84 mph FB (1986) for strikes. Mixed a tight mid-60’s CB with two-plane shape and commanded 73-75 mph CH with fade.
