7/01/26
Justice Diaz, Adrienne C. Nelson (OR), 2027
Positional Profile: 3B/RHP
Body: 5-10, 197-pounds.
Delivery: Narrow base as body sets from 1B edge of the rubber. Works from the full wind with hands set at the chin and body square to target. Drop step first move turns body toward 3B through wind. Head drops from target through shorter leg lift and stride. Firm front side land with momentum through home plate.
Arm Action: RH. Longer, low arm swing after hands break at the letters. Lower 3/4 slot release with tucked gloveside follow.
FB: T79, 77-79 mph. T2037, 2000 average rpm.
CB: 68-69 mph. T1991, 1900 average rpm.
SL: 70-70 mph. T1867, 1809 average rpm.
CH: 74-75 mph. T1803, 1798 average rpm.

7/01/26
Justice Diaz, Adrienne C. Nelson (OR), 2027
Positional Profile: 3B/RHP
Body: 5-10, 197-pounds.
Hit: RHH. Weight evenly distributed with slight bend in knees in stance. Hands away from frame with barrel stacked at 45 degrees and subtle rhythm pre-pitch. Standard stride as hands lower then retract in load. Tight turn through the zone with slight uphill path. Catches ball out front with head down through contact. Loose-wristed stroke with two-handed finish. 69.1 mph bat speed with 9.8 G's of rotational acceleration.
Power: 96 max exit velocity, averaged 88.3 mph. 364' max distance.
Arm: RH. INF-77 mph. Standard 3/4 slot release with longer swing and low gloveside follow.
Defense: Bounce in step pre-pitch with controlled first step. Works to position body around and through ball with momentum carried through target. Fields near center of frame and funnels ball to belt before releasing.
ATH: 6.81 runner in the 60. 1.69 and 3.86 in the 10 and 30 yard splits. 23.00 max vertical.
Vizual Edge: 63.81 Edge Score
2/14/26
Justice Diaz, Adrienne C. Nelson (OR), 2027
Positional Profile: 3B/RHP
Body: 5-9, 197-pounds.
Delivery: Goes from the full wind up with feet together and pointed to the third base line, shifted to the first base side of the rubber. Hands set at the chin before working into the windup shifting back foot to near center of rubber before front foot lifts into short stride down the mound into landing with bend in the knee. Balanced mechanics to release then higher trail leg carries momentum back to first base side.
Arm Action: RH. Hands break downwards at the letters into a short arm swing up to a 3/4 arm release.
FB: T78, 76-78 mph. T1893, 1841 average rpm.
CB: 66-68 mph. T1774, 1751 average rpm.
SL: 67-68 mph. T1961, 1942 average rpm.
CH: 71-72 mph. T1726, 1657 average rpm.
ATH: 7.25 runner in the 60. 1.76 and 4.08 in the 10 and 30 yard splits. 17.70 max vertical.
2/14/26
Justice Diaz, Adrienne C. Nelson (OR), 2027
Positional Profile: 3B/RHP
Body: 5-9, 197-pounds.
Hit: RHH. Feet are set more than shoulder width apart with weight even on both feet and bend in both knees, feet are square to the plate. Front shoulder is closed with hands more relaxed shoulder high and bat stacked more vertically over hands. Front foot lifts and lands as hands slowly load back away from the body then hips break fast causing hands to pull through the zone with uphill contact on the ball. Head stays on the ball to contact with weight staying back through the swing finishing with a hard two-handed follow-through. 68.1 mph bat speed with 8 G's of rotational acceleration.
Arm: RH. INF-78 mph. Hands gather and break at the letters up into quick 3/4 arm release.
Defense: Shows glove early on prep step staying relaxed and taller. Drops at the hips into lower stance on approach to the ball, works body position well around the ball to keep momentum to target. Comfortable fielding near center frame both forehand and backhand.
ATH: 7.25 runner in the 60. 1.76 and 4.08 in the 10 and 30 yard splits. 17.70 max vertical.
Vizual Edge: 66.36 Edge Score
