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
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Adler Holtz, Valparaiso High School (IN), 2025
Positional Profile: RHP/SS
Body: 6-3, 200-pounds. Tall, projectable frame.
Hit: RHH. Starts in a taaller, relaxed stance. Slightly open. Toe tap into stride on load. Hands get good separation. 79.8 mph bat speed with 22 G's of rotational acceleration.
Power: 100 max exit velocity, averaged 88.3 mph. 320' max distance. 100.1 max exit velocity, averaged 88.3 mph. 320' max distance.
Arm: RH. INF-91 mph. Long arm action from over-the-top arm slot.
Defense: Solid footwork, keeps feet active. Stays light on feet. Moves well into fielding position. Quick exchanges, smooth and under control movement.
ATH: 7.25 runner in the 60. 7.25 runner in the 60.
'25 RHP/SS Adler Holtz (Valparaiso HS) was another prospect that has seriously elevated his game this offseason. Holtz improved his fastball from 77-80 mph at last summer's Northwest Indiana Open, now sitting 84-87, touching 88 mph. The proportional, 6-foot-2, 195 pound right-hander works with little effort from an over-the-top slot to create downhill angle on a riding fastball (16"+ IVB). I really liked how easy the delivery was, allowing him to fill the zone consistently with all three of his offerings. The fastball is certainly his best pitch, but he also showed an 11/5 shaped curveball with depth at 71-72 mph, and flashed a changeup at 73-75 mph. I like Adler as an arm more than as a bat, but he did show some two-way prowess as a physical infielder with plenty of arm strength (89 mph across) and solid bat strength (96 mph exit velocity).
Adler Holtz, Valparaiso High School (IN), 2025
Positional Profile: SS/RHP
Body: 6-2, 185-pounds. Proportional build
Delivery: Simple, stretch-only delivery with low-effort. Quick, athletic lift that gets to a strong balance point. Short stride down the slope with in-line shoulders. Finishes with balance.
Arm Action: RH. Long arm action from an over-the-top slot.
FB: T81, 77-80 mph. Straight FB w/ some ride T1872, 1732 average rpm.
CB: 61-65 mph. Gradual break, 11/5 shape T1900, 1846 average rpm.
CH: 65-67 mph. Some fade - shows feel for command of CH. T1750, 1628 average rpm.
ATH: 7.92 runner in the 60. 1.85 and 4.31 in the 10 and 30 yard splits.
Adler Holtz, Valparaiso High School (IN), 2025
Positional Profile: SS/RHP
Body: 6-2, 185-pounds. Proportional build
Hit: RHH. Sets up in a tall stance & uses a short, simple stride with a small load of the hands - hands load up & back to get into a strong hitting position at heel strike. Has some whip in the barrel - path works slightly uphill to match plane. Shows gap-to-gap strength.
Power: 91 max exit velocity, averaged 85.0 mph. 323' max distance.
Arm: RH. INF-86 mph. Long arm action from an over-the-top arm slot - good arm strength.
Defense: Fundamental actions. Consistent footwork that plays through the baseball. Soft hands - shows feel to play with one-hand. Exchanges are quick & clean. Playable actions that should translate to gameplay, likely 3B long-term.
ATH: 7.92 runner in the 60. 1.85 and 4.31 in the 10 and 30 yard splits.
