On Tuesday, July 1st, 2025, the Prep Baseball Utah staff hosted its first big event of the summer, with around 50 prospects on deck. This group featured players from the 2026–2029 classes, many of whom turned in standout performances that caught our staff’s attention.

All players went through a full workout that included batting practice tracked by TrackMan and BLAST, a 60-yard dash recorded by VALD Performance, and defensive evaluations with positional velocities. Pitchers threw 15–20 pitch bullpens with TrackMan recording all of their pitches, giving us an in-depth look at how their stuff plays.

Over the next few days, we’ll be rolling out post-event coverage spotlighting top performers, stat leaders, and more. Stay tuned to our social channels for video highlights, leaderboards, and continued content from the event.

Yesterday, we released our Statistical Analysis, highlighting some of the top overall data performances. Today, we take a closer look at the TrackMan Pitching data collected during the bullpen sessions at the Salt Lake City Summer ID.

FASTBALL

MAX VELOCITY (MPH)

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

SPIN RATE (AVG)

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.

INDUCED VERTICAL BREAK (AVG.)

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. IVB is also a huge part of the vertical approach angle.

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.”
