As the summer of 2025 comes to a close, the Prep Baseball Alabama staff took a moment to reflect on a busy and exciting slate of events across the state.

Over three months, we saw standout talent from every part of Alabama, and now we’re diving into the numbers to spotlight the top statistical performers from our summer events. From explosive arms to big-time bats, this summer had it all, and the data backs it up.

Up next, we break down the top average fastball induced vertical break from the summer circuit. Please note that this leaderboard includes all events from summer Scout Days, Summer ID's, Rising Stars ID's, Future Games, Senior Future Games, Junior Future Games, Southeast Super Sophomore Games, and the Yellowhammer State Games.

Top Average Fastball Induced Vertical Break

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.
