JJ Herzog, NA (TX), 2029
Positional Profile: OF/LHP LHP will get stronger. Moves well on mound. Repeats delivery, can firm getting over front side. Cutoff circle creates some deception, looking for arm speed to increase with added strength and physical maturity. FB will develop more velocity, will firm ability to work around zone as timing to delivery and arm action firms. CB and SL developing, looking for release point to firm. CB/SL show different shapes, will be effective when command firms. Nice upside to young LHP.
Body: 5-7, 151-pounds. Projects well physically. Width to shoulders and back projects well for added strength.
Delivery: Stretch only, knee lift with inward turn of hip and shoulder. Slight push out of foot, works down the slope. Upright, work to get over front side more with chest. Spinoff finish.
Arm Action: LH. Cutoff circle. Fair extension to release, solid finish. Arm speed will develop. Late at times with front shoulder running away from arm, stay on time with delivery.
FB: T75, 70-74 mph. Arm side tail present. T2074, 1966 average rpm.
CB: 57-59 mph. Shows nice spin developing. Gets on side, work to stay on top. Depth present when landed. T1944, 1861 average rpm.
SL: 62-63 mph. Shows developing feel for pitch. Nice down finish at times. Release point can be firmed. T1733, 1640 average rpm.

Positional Profile: OF/LHP LHH/OF/INF…solid bat/power combo in future. Solid defensive player, moves well on baseball field. Solid bat/power combo in future with adjustments, will take patience. Does have solid base to work from.
Body: 5-7, 152-pounds. Width to shoulders and back. Will have strength to body in future.
Hit: LHH. Upright stance, lands in good position to hit. Rotational back foot, lower 1/2 works fine in swing. Barrel/hands start in good position to hit. With start of swing, gets lead arm bar with separation at stride, dumps barrel around creating length to swing. Lead elbow flares up with swing. Work to soften elbow with stride, eliminating lead arm bar. Take direct path to zone with barrel. Lead arm/elbow can be up, don't let it flare up with swing. Adjustments will take time.
Power: 88 max exit velocity, averaged 78.4 mph. 287' max distance. Project solid bat/power combo in future with adjustments. Will take time to make adjustments, will be solid in time.
Arm: LH. INF-71 mph. OF-75 mph. OF…cutoff circle with length to backside, low slot. Would like to see development of full circle arc circle. Work to keep elbow up throwing and staying behind baseball with hand for carry to throws. 1B…arm works well with solid throws.
Defense: OF…Moves well to baseball, nice job of breaking down to field. feet. Hands set in good position, would like to see bit more out in front. 1B…Moves well to baseball, hands work fielding. Solid base to develop from, will solid infielder in future.
ATH: 7.60 runner in the 60. 1.87 and 4.26 in the 10 and 30 yard splits. Good start, good stride length. Upright runner with shoulders and head up for last 40 yards approx. Work to get lean forward with shoulders and head.
