Staff

FLOWERY BRANCH, GA - The Preseason All-State Underclass Showcase travels to IVSA where this invite-only event that features the top prospects from the 2028 and 2029 grad classes. Every year, the Preseason All-State Showcase highlights the "Who’s Who" of the Georgia baseball landscape. This event is limited and exclusive to the top prospects in Georgia and serves as a springboard as you enter the high school season. Throughout the week we will be pumping out the content from this event. Today, we present the stat leaderboards with the help from our tech partners from this event. More articles and content wil be on the way to break down the entirety of the data collected. 

Inside today’s Pitching Data dive we will highlight the players with top metrics per Trackman. 

Today, we will take an even closer look at the pitchers in attendance with the help of our tech partners, broken down by the categories and leaderboards below.

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.

SPIN EFFICIENCY% (AVG.)

Rank Name State School Class Pos Spin Efficiency % (avg)
1 Tripp Swords GA Eastside 2028 SS 94 %
2 James Brooks GA South Effingham 2028 SS 94 %
3 Lawson Moore GA Gatewood 2028 LHP 94 %
4 Graham Stacey GA Ola 2028 3B 94 %
5 Jax Choi GA Mill Creek 2029 RHP 93 %

8 Will Bracken GA Fellowship Christian 2028 RHP 92 %
9 Cole Roberts GA Walnut Grove 2028 3B 91 %
10 Cayden Mader GA Grayson 2028 3B 91 %

Spin Efficiency: This metric is the percentage of the raw spin rate that directly impacts pitch movement; so while raw spin is measured by revolutions per minute (rpm), spin efficiency is the ratio of true spin divided by raw spin. It’s important to understand that more is not always better when it comes to spin efficiency. The optimal spin efficiency on a pitch depends on the pitch type and should be understood in the context of a pitcher’s entire arsenal. Regarding the true four-seam fastball, a spin efficiency close to 100 percent is preferable, indicating that nearly all the backspin generated on the ball as it leaves the pitcher’s hand is contributing to the “riding” action the pitch has as it enters and exits the strike zone, making it especially effective in the upper third of the strike zone.

INDUCED VERTICAL BREAK (AVG.)

Rank Name State School Class Pos IVB (avg)
1 Jax Choi GA Mill Creek 2029 RHP 23.6 in
2 JR Pearse GA Wheeler High School 2029 OF 21.8 in
3 Nicholas Kupsco GA Chamblee Charter High School 2029 RHP 21.5 in
4 Graysen Radics GA Wesleyan 2029 OF 20.8 in
5 Asher Laur GA Jackson County 2029 RHP 19.8 in
6 James Callaway GA Denmark 2028 RHP 19.2 in

9 Cal Williamson GA North Atlanta 2028 LHP 18.8 in
10 Tripp Swords GA Eastside 2028 SS 18.7 in

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 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.”
