2025 Summer Rewind: Player Data & Analytics

The summer of 2025 provided players across North Carolina with valuable opportunities to continue their on-field development through practices, workouts, events, games, and tournaments. While the summer schedule can be demanding, most players approach it with a clear plan—testing their abilities, gaining exposure, and identifying areas for growth.

Throughout the season, Prep Baseball scouts worked diligently to evaluate as many players as possible. Tournament play offered game-based assessments, while Prep Baseball events provided controlled settings to capture verified metrics, statistics, analytics, and video. As a result, more than 600 players from North Carolina were added to the rankings database this summer, each earning a player grade based on their measurable tools and performance.

With that information compiled, the updated class rankings offer a clearer picture of how players across the state are progressing. The Summer Rewind series takes a closer look at these evaluations, highlighting standout performances from Prep Baseball events. These range from Team Carolina IDs and Organizational Scout Days—focused on data collection—to premier events such as the NC/SC Border Battle, Top Prospect Games, and the Future Games, where top players measure themselves against elite competition in North Carolina and across the country.

In this series, we will also spotlight leaders in ball flight data, swing metrics collected through BLAST Motion, and athletic testing powered by VALD Performance. These tools, integrated into Prep Baseball events, ensure that players are evaluated with precision, making Prep Baseball the most trusted name in amateur baseball scouting.

TRACKMAN PITCHING DATA - NC SUMMER EVENTS 2025

FASTBALL

MAX 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.

HIGHEST AVG. HORIZONTAL MOVEMENT

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.
