On March 10th, Prep Baseball Wisconsin hosted one of its largest events on the state’s showcase calendar: the Madison Preseason ID at GRB Academy in Windsor, Wis. Nearly 150 players from across the state met in the Madison area to participate in this event, a Preseason ID that consistently provides our staff with need-to-know names and players to consider for future invite-only events, like the PBR Future Games, among others.

Yesterday, we published our Statistical Analysis, where we broke down the stat leaders from the more traditional categories and our Quick Hits, where we dove into some of the top players from the event. Today, we will take a further in-depth look at the top pitchers with the help of our tech partnerships, broken down by the categories down below:

TRACKMAN

FASTBALL

VELOCITY (MAX)

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.”

STRIKE ZONE RATE%

Average MLB pitchers throw 62% strikes, and better pitchers throw strikes 65% of the time, or roughly 2:1 strikes to balls.
