2023 Senior State Games: Data Dive, Pitchers


PBR Florida
PBR Florida Staff

The 2023 Senior State Games took place September 23-24 at Holman Stadium in Vero Beach, FL. The event featured players from the 2024-2025 classes participating in a pro-style workout and three games over the two day span in front of the PBR Florida Scouting Staff.

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

Monday, we broke down the stat leaders from the more traditional categories in our Statistical Analysis. 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.

FASTBALL 

MAX VELOCITY (MPH)

Rank Name State School Class Pos Velocity (max)
1 Chayce Kieck FL Bolles 2024 RHP 89.5 mph
2 Noah Campbell FL Mulberry 2024 RHP 88.6 mph
3 Amarri Daniel FL Sunshine State Elite Academy 2024 3B 88.2 mph
4 Brady Wright FL East Lake 2024 RHP 87.9 mph
5 Jael Hernandez FL Monarch 2024 SS 87.8 mph

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Jael Hernandez FL Monarch 2024 SS 2423 rpm
2 Brady Wright FL East Lake 2024 RHP 2359 rpm
3 Cooper Emery FL Lakeland 2024 RHP 2288 rpm
4 Chayce Kieck FL Bolles 2024 RHP 2283 rpm
5 Jackson Leggett-Walford FL Palm Harbor University 2024 LHP 2276 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 Amarri Daniel FL Sunshine State Elite Academy 2024 3B 94 %
2 Christian Borbely FL Montverde Academy 2024 RHP 93 %
3 Marshall Cobb FL Vero Beach 2025 RHP 92 %
4 Dane Rossi FL American Heritage Delray 2024 LHP 92 %
5 Jael Hernandez FL Monarch 2024 SS 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 Christian Borbely FL Montverde Academy 2024 RHP 19.5 in
2 Andrew McWilliams FL Bishop Kenny 2024 RHP 19.0 in
3 Cooper Emery FL Lakeland 2024 RHP 18.3 in
4 Chris Miranda FL Miami Springs 2024 RHP 18.3 in
5 Ryley Chapman FL Lake Brantley 2024 SS 18.3 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 Jael Hernandez FL Monarch 2024 SS 18.3
2 Rolando Castillo FL Mater Lakes Academy 2024 LHP -14.9
3 Daniel Milian FL MIAMI BEACH SENIOR HIGH SCHOOL 2024 LHP -14.9
4 Amarri Daniel FL Sunshine State Elite Academy 2024 3B 14.9
5 Vincent Cooke FL Jensen Beach 2025 RHP 13.9

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.”
