ZT Prospects East : Data Dive Pitchers
October 23, 2026
Prep Baseball North Carolina continued its fall Scout Day schedule on Wednesday, October 14, hosting the Prep Baseball Scout Day: ZT Prospects East at Terry Sanford High School in Fayetteville, NC. The event provided players from the ZT Prospects East organization, along with invited players from Terry Sanford HS, an opportunity to showcase their development and update their Prep Baseball profiles with verified statistics, video, and scouting evaluations.
The workout opened with a laser-timed 60-yard dash, capturing each player's overall time and 10-yard split to provide additional insight into acceleration and explosiveness.
Players then moved into the offensive portion of the workout, completing multiple rounds of batting practice. Defensive evaluations followed, with players showcasing their abilities at their primary positions. The Prep Baseball scouting staff evaluated athleticism, movement, hands, footwork, arm strength, carry, and accuracy.
The event concluded with controlled bullpens, giving pitchers and catchers a final opportunity to showcase their abilities. The scouting staff evaluated each pitcher's delivery, pitch arsenal, stuff, command, and overall effectiveness on the mound.
Prep Baseball North Carolina will continue its coverage of the ZT Prospects East Scout Day with statistical leaderboards, scouting notes, and additional analysis highlighting the players and performances that stood out.

FASTBALL
MAX FASTBALL VELOCITY
| Rank | Name | State | School | Class | Pos | Velocity (max) |
| 1 | Gavin Bynum | NC | Terry Sanford High | 2029 | RHP | 86.5 mph |
| 2 | Conner Jackson | NC | Terry Sanford High | 2029 | RHP | 78.2 mph |
| 3 | Andrew Peavey | NC | Gray's Creek | 2031 | OF | 78.1 mph |
| 4 | Matthew Nash | NC | Gray's Creek | 2032 | 1B | 71.6 mph |
| 5 | Preston Locklear | NC | South View High | 2032 | 3B | 71.1 mph |
Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.
HIGHEST AVG. SPIN RATE
| Rank | Name | State | School | Class | Pos | Spin Rate (avg) | Spin Efficiency % (avg) |
| 1 | Andrew Peavey | NC | Gray's Creek | 2031 | OF | 2174 rpm | 87 % |
| 2 | Gavin Bynum | NC | Terry Sanford High | 2029 | RHP | 2023 rpm | 81 % |
| 3 | Conner Jackson | NC | Terry Sanford High | 2029 | RHP | 2014 rpm | 77 % |
Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.
HIGHEST AVG. IVB
| Rank | Name | State | School | Class | Pos | IVB (avg) | Velo Range |
| 1 | Preston Locklear | NC | South View High | 2032 | 3B | 21.3 in | 68.7-70.2 mph |
| 2 | Raiden Manalili | NC | John Griffin Middle School | 2032 | RHP | 20.0 in | 56.9-58.2 mph |
| 3 | Andrew Peavey | NC | Gray's Creek | 2031 | OF | 19.4 in | 76.5-78.1 mph |
Induced Vertical Break: Used in short form as "IVB," this metric is most important on fastballs for creating rise and on curveballs for creating depth – it can also have some use when measuring sliders and cutters as well. Sliders tend to be closer to zero inches while cutters are generally between 5 and 15 inches. Usually fastballs and curveballs with large IVB have higher spin efficiencies as well. Sliders generally have very little (closer to zero) IVB and very low spin efficiency. You could also categorize IVB into spin rate as this is part of the “useful movement” you’re looking for, and it’s also important to consider the pitch’s velocity as well as its release height when evaluating IVB measurements against each other.
HORIZONTAL MOVEMENT (AVG.)
| Rank | Name | State | School | Class | Pos | HM (avg) | Velo Range |
| 1 | Gavin Bynum | NC | Terry Sanford High | 2029 | RHP | 13.4 | 84.6-86.0 mph |
| 2 | Matthew Nash | NC | Gray's Creek | 2032 | 1B | 12.5 | 68.8-71.1 mph |
| 3 | Conner Jackson | NC | Terry Sanford High | 2029 | RHP | 10.8 | 76.6-78.1 mph |
Horizontal Break: Outlined on TrackMan’s own website: “... horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.”
HIGHEST STRIKE ZONE RATE%
| Rank | Name | State | School | Class | Pos | Zone % | Velo Range |
| 1 | Cooper Johnson | NC | Midway High | 2032 | RHP | 70 % | 65.4-69.8 mph |
| 2 | Matthew Nash | NC | Gray's Creek | 2032 | 1B | 42 % | 68.8-71.1 mph |
| ^ | Gavin Bynum | NC | Terry Sanford High | 2029 | RHP | 42 % | 84.6-86.0 mph |
| 3 | Penn Harrelson | NC | Midway Middle | 2032 | SS | 25 % | 59.3-61.9 mph |
For some context, in 2023 MLB pitchers averaged an In Zone% of around 49 percent in live game settings measured across all pitch types, according to Statcast.
