This past Tuesday, the Prep Baseball Arizona staff hosted it's third Summer ID event with the Peoria Summer ID. This event featured roughly 26 prospects in the 2026–2029 classes and provided a valuable opportunity for young athletes to get quality reps in a structured setting and compete in front of our staff. After some of the standout performances on Tuesday, it is clear that the uncommitted talent pool in Arizona is deep.

Players also received video footage and verified stats added to their profiles, giving them a head start in building their recruiting presence. Summer ID's also serve as key identifiers for Arizona’s Junior Future Games Team, which will head to LakePoint Sports in late July to take on top talent from across the country.

All players ran through a full workout that included batting practice and bullpens captured on our TrackMan and BLAST, as well as the 60-yard dash captured by VALD Performance and positional drills including velocities. Over the next several days we'll be highlighting top performers from the event within our post-event analysis. Stay locked into our social media channels over the next several days as we continue to push out video, leaderboards and more.

Yesterday, we released our Statistical Analysis, where we highlighted some of the top overall performances from the event. Today, we will look into the pitchers and some of the top TrackMan data from the Peoria Summer ID, with some impressive uncommitted arms on board.

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.”
