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

A Future Games participant as a member of team PBR Nevada in 2020, AJ moved to Utah this past January to attend Crimson Cliffs, which is an hour and half from where he was raised in the Las Vegas area. A versatile player as he can play both OF corners, but his home and more comfortable spot is 1B. A strong RH hitter with present strength and the ability to drive the ball to the pull side, AJ does wrap his top hand on the bat and this needs to be tweaked to get him to a more conventional position of palm up/palm down. A sponge and receptive and coachable with an engaging personality, AJ has some untapped potential with the bat moving forward and does need some intricacy type stuff at 1B defensively to unlock his full potential. Will be a cog in the order over the next couple of years at Crimson Cliffs, whether that’s 1B, OF corner and DH to get his bat in the order, as Crimson has a strong 2023 class.
Body: 6-foot-0, 185 pounds. Developing, athletic build with some present strength in his lower half. His frame allows for significant gains strength and size.
Defense: 1B. Athletic around the bag. Mechanical sound with some tendency to sit back. Footwork is improving. Presents good target with ability to handle balls in the dirt.
Arm: RH. 74 mph. Quick, short action. Accurate.
Hit: RHH. Wide, athletic set up. Hands close to body, shoulder height. Simple rock back load with pick up/put down stride. Efficient to the ball with a level bat path. Natural lift through extension. Line drive producer with some loud contact during his BP session. Can drive the ball to all fields. Present power to the pull side.
Power: 94 mph Exit Velocity via TrackMan
Run: 7.51 Laser Timed 60
