Prep Baseball Florida Staff

The East Florida Top Prospect Games took place on Tuesday, June 2, at Cacti Park in West Palm Beach, FL. The event featured players from the 2027-2029 classes participating in a pro-style workout, followed by gameplay in front of the Prep Baseball Florida Scouting Staff.

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

Wednesday, we broke down the stat leaders from the more traditional categories in our Statistical Leaderboards. 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 (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Jacob Holley FL West Orange High 2028 RHP 2299 rpm
2 Ryan Musa FL Belen Jesuit Prep 2028 RHP 2210 rpm
3 Tyler Stertzbach FL Stoneman Douglas 2028 RHP 2108 rpm
4 William Miller FL St. Thomas Aquinas 2029 RHP 2104 rpm
5 Austin Nash FL Calvary Christian High School 2027 RHP 2015 rpm
6 Kline Cummings FL The Bolles School 2028 LHP 2011 rpm
7 Aidan Giedrys FL Spruce Creek High School 2027 RHP 1968 rpm

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 Kline Cummings FL The Bolles School 2028 LHP 95 %
2 Ryan Musa FL Belen Jesuit Prep 2028 RHP 92 %
3 William Miller FL St. Thomas Aquinas 2029 RHP 91 %
4 Austin Nash FL Calvary Christian High School 2027 RHP 90 %
5 Jacob Holley FL West Orange High 2028 RHP 89 %
6 Tyler Stertzbach FL Stoneman Douglas 2028 RHP 85 %
7 Aidan Giedrys FL Spruce Creek High School 2027 RHP 79 %

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 Kline Cummings FL The Bolles School 2028 LHP 18.2 in
2 Ryan Musa FL Belen Jesuit Prep 2028 RHP 16.8 in
3 Aidan Giedrys FL Spruce Creek High School 2027 RHP 16.6 in
4 Tyler Stertzbach FL Stoneman Douglas 2028 RHP 16.0 in
5 William Miller FL St. Thomas Aquinas 2029 RHP 15.4 in
6 Jacob Holley FL West Orange High 2028 RHP 13.4 in
7 Austin Nash FL Calvary Christian High School 2027 RHP 13.3 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 MOVEMENT (AVG.)

Rank Name State School Class Pos HM (avg)
1 Jacob Holley FL West Orange High 2028 RHP 16.2
2 Austin Nash FL Calvary Christian High School 2027 RHP 15.4
3 Ryan Musa FL Belen Jesuit Prep 2028 RHP 13.6
4 Tyler Stertzbach FL Stoneman Douglas 2028 RHP 13.3
5 William Miller FL St. Thomas Aquinas 2029 RHP 11.2
6 Kline Cummings FL The Bolles School 2028 LHP -6.9
7 Aidan Giedrys FL Spruce Creek High School 2027 RHP 2.8

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.”
