GBC Scout Day: Full Workout & Data Breakdown at Proehlific Park & Greensboro Batting Center

On Friday, February 13, 2026, Prep Baseball was on site at Proehlific Park & Greensboro Batting Center for a Scout Day with GBC . The event featured a full pro-style workout, giving players the opportunity to showcase their tools in a complete, data-driven evaluation setting.

Position players worked through a defensive workout before taking batting practice with TrackMan capturing ball flight data throughout each round. Pitchers threw controlled bullpen sessions with TrackMan tracking pitch metrics, movement profiles, and overall performance data. Every swing and every pitch was measured, allowing our staff to pair in-person evaluation with verified analytics.

Athletic testing was also a key component of the day. Players ran a laser-timed 60-yard dash, including 10-yard and 30-yard splits, powered by VALD Athletics’ laser timing system to ensure precise results. Between speed metrics, offensive data, pitch analytics, and defensive evaluations, athletes left the day with a comprehensive statistical profile to complement their video and scouting notes.

In the coming weeks, we will roll out a series of leaderboards and statistical breakdowns from the GBC Scout Day, highlighting top performers across various categories — from exit velocity and power production to pitch metrics, speed, and more. Each post will spotlight the measurable standouts and provide context behind the numbers.

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) as the pitch carries through the zone. Low-spin fastballs typically indicate greater horizontal action, often making them tougher to square up but generally easier to make contact with, leading to more ground balls. High-spin fastballs show a correlation with swings and misses.

HIGHEST AVG. IVB

Induced Vertical Break (IVB): 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 be useful when measuring sliders and cutters. Sliders tend to be closer to zero inches, while cutters are generally between 5 and 15 inches. Fastballs and curveballs with large IVB usually have higher spin efficiency. Sliders generally have very little (closer to zero) IVB and low spin efficiency. It’s important to consider pitch velocity and release height when evaluating IVB measurements.

HORIZONTAL MOVEMENT (AVG.)

Horizontal Break: Horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-to-side and where it would have crossed if 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.

HIGHEST STRIKE ZONE RATE%

For 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.
