Wilmington Summer ID / Post 10 Scout Day: Data Dive - Pitchers


Sean Smith
Mid-Atlantic Operations Manager

WILMINGTON, NC -- On Saturday, May 16th, Prep Baseball North Carolina was back in Wilmington for the 2026 Wilmington Summer ID and the Wilmington Post 10 Scout Day, held together at Buck Hardee Field at Legion Stadium. The event featured players from the 2026-2031 grad classes, giving our staff an opportunity to evaluate a wide range of talent from across the region in a full showcase setting.

Players opened the workout with laser-timed 60-yard dashes, collecting 10-yard and 30-yard split data along the way. Position players then moved through an offensive workout that included multiple rounds of batting practice on the field with TrackMan technology capturing ball flight and batted ball data, while players attending the ID also received BLAST swing metrics. Defensively, players worked through position-specific evaluations, allowing our scouting staff to gather looks at athleticism, footwork, hands, exchanges, arm action, and overall defensive actions while recording arm strength data across the field.

Additional athletic testing, including jump metrics, was also collected throughout the day. Pitchers wrapped up the event with controlled bullpen sessions featuring TrackMan ball flight data, giving an in-depth look into pitch metrics, movement profiles, and overall arsenal evaluation.

Over the coming days, Prep Baseball NC will continue to release statistical leaderboards, scouting notes, and player reports from both events.

WILMINGTON SUMMER ID / POST 10 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.
