Aidan Nieto, Tesoro High (CA), 2026
Positional Profile: 1B/RHP Intriguing two-way talent that capitalizes on frame in the box and works with deception on the mound.
Body: 6-5, 206-pounds. Long-limbed, wiry frame with present strength and room to add more.
Delivery: Works exclusively from the stretch with hands set at the belt, syncing with the front leg. Utilizes a high leg kick with an inward hip turn and sinks slightly into the back knee as the front leg leads down the mound, finishing with a late push off the drive leg. Shows solid feel for blocking with the plant leg, with hips working well around it. Maintains direction consistently throughout the delivery. Has room to refine lower half and add velocity.
Arm Action: RH. Delivers with a compact arm path that features a quick break out of the glove. Works from a high 3/4 slot with a consistent release point. Displays present arm speed and room to add velocity with a longer path. Hides the ball well behind the frame and finishes with some recoil upon release.
FB: T85, 81-84 mph. FB with ride that sneaks up on hitters with late life due to extension length. North/South approach, but effective to all four quadrants. Misses barrels when elevated. Displays some tail when thrown to arm-side. T2129, 2018 average rpm.
SL: 71-73 mph. Sharp break that plays well North/South FB plane. Displays moderate vertical drop when thrown down in the zone. Gets more sweep when thrown to the glove side edge. T2267, 2130 average rpm.
CH: 75-77 mph. High spin CH with heavy arm-side fade. Separates well off the FB. T2027, 1877 average rpm.
ATH: 20.70 max vertical.

Aidan Nieto, Tesoro High (CA), 2026
Positional Profile: 1B/RHP Intriguing two-way talent that capitalizes on frame in the box and works with deception on the mound.
Body: 6-5, 206-pounds. Long-limbed, wiry frame with present strength and room to add more.
Hit: RHH. Starts from an upright posture with a wide, balanced stance. Hands rest behind the back shoulder with a vertical barrel and a pronounced waggle. Initiates the load by shifting weight into the back side as the hands drift back slightly and the back elbow raises. Utilizes a subtle leg lift for timing, leading into a short, controlled stride forward. Drives the hip turn with the back knee, creating decent separation and working with a short, compact stroke direct to the ball. Uphill barrel path stays on top while relying on his frame to generate natural carry. Works primarily to the pull side with some present pop. 66.2 mph bat speed with 12 G's of rotational acceleration.
Power: 98 max exit velocity, averaged 86.2 mph. 359' max distance.
Arm: RH. INF-75 mph. Short arm path that takes time to come out of the glove, working from a 3/4 slot with the ability to drop down when needed. Shows some feel for accuracy, though release point will need refinement.
Defense: Sinks low pre-pitch, showing soft hands that stay high until the gather. Works downhill with lengthy, direct strides and intent through the ball. Profiles best at 1B.
ATH: 20.70 max vertical.
Vizual Edge: 52.42 Edge Score

Nieto boasts an intriguing 6'5 215 lbs. frame with wiry present strength that has room to fill out more as he matures in the coming years. The Tesoro High product earns his spot on this list both for his performance as a RH hitting 1B who collected a pair of knocks over four total plate appearances while drawing a walk to reach base three times. But, also for how his deceptive short arm delivery with an 83-85 MPH FB performed over three innings of work. Nieto hides the ball behind his body effectively before popping out a quick FB that appeared to get on hitters with more life than just his pure velocity would suggest and backing the offering up with a 75-77 MPH CHG and 71-75 MPH SLD. Nieto attacked the strike zone aggressively picking up called strikes and whiff from hitters over his outing to record a total of 7 Ks. The Orange County based product will be an interesting follow as an uncommitted 2026 for college programs.
