On Deck O's Scout Day: Data Dive Pitchers

2026 Prep Baseball Scout Day: On Deck O’s
Prep Baseball North Carolina continued its fall Scout Day schedule with the 2026 Prep Baseball Scout Day: On Deck O's, working with players from the organization across two workout dates. Splitting the event allowed On Deck to continue with its fall development plan while giving Prep Baseball scouts an opportunity to collect updated statistics, analytics, video, and evaluations on the players in attendance.
The first portion of the workout was held on Wednesday, September 9th, featuring bullpens, running evaluations, and defensive work. Arm velocities and catcher pop times were recorded during the defensive evaluations, while pitchers worked through controlled bullpens with TrackMan capturing ball-flight data on each pitch.
Players returned on Wednesday, September 16th for the offensive portion of the evaluation. Hitters worked through rounds of batting practice with TrackMan tracking each batted ball, providing verified exit velocities, distances, and additional ball-flight metrics.
Each participating player will also receive an updated Prep Baseball profile video in the coming weeks. Combined with the statistics and advanced analytics collected during the two workouts, the video provides another tool for college coaches and professional scouts to track and assess players as they continue to grow and develop.
Prep Baseball NC will break down the On Deck O's Scout Day through statistical leaderboards, data analysis, and scouting coverage highlighting the players and performances from the event.

ON DECK O'S SCOUT DAY DATA DIVE - PITCHERS
FASTBALL
MAX FASTBALL VELOCITY
Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.
HIGHEST AVG. SPIN RATE
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
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.)
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%
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.
