TN Top Prospect Games: Data Dive, Pitchers


Colin Chamblin

NASHVILLE, TN - The Prep Baseball Tennessee Top Prospect Games was held on Tuesday, May 28th at Vanderbilt University, followed by game play the next day on May 29th at Grace Christian Academy in Franklin, TN. This event was an invite-only event that consisted of some of the top players from the 2025-2027 classes from across Volunteer state. Players went through an extended pro-style workout that included batting practice using Trackman, ran the 60-yard dash using Swift Performance, and much more. Pitchers were able to get numbers and metrics on TrackMan during game play. There were some players who showed up and continued to build off of prior performances, but there were also some new names who jumped onto our radar with a strong showing at the event.

Continuing our post-event coverage for this event, we take a look at some of the standouts from the event. Below you will see the Pitching Leaderboards from the TN Top Prospect Games.

10 Adam Riley TN Jo Byrns High School 2026 RHP 88.7 mph

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Harrison Pollina TN Arlington 2026 RHP 2387 rpm
2 Hiram Lewis TN Ravenwood High School 2025 RHP 2385 rpm
3 Cayden King TN MIDDLE TENNESSEE CHRISTIAN SCHOOL 2026 RHP 2366 rpm
4 Noel LeBlanc MS LAUSANNE COLLEGIATE SCHOOL 2025 RHP 2363 rpm
5 Jackson Goddard TN Liberty Creek High School 2026 SS 2271 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 Gavin Bergeron TN Bearden High School 2026 SS 99 %
2 Matt Dill TN The Baylor School 2025 3B 98 %
3 Tyler Bennett TN CHRISTIAN ACADEMY OF KNOXVILLE 2025 SS 98 %
4 Porter Murff TN Clarksville High 2026 LHP 96 %
5 Graham King TN BAYLOR SCHOOL 2026 OF 96 %

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 Gavin Bergeron TN Bearden High School 2026 SS 23.9 in
2 Andrew Smith TN Maryville High School 2026 OF 23.5 in
3 Dominic Malich TN White House Heritage 2025 RHP 22.4 in
4 Jackson Goddard TN Liberty Creek High School 2026 SS 20.7 in
5 Rhett Slagle TN Elizabethton High School 2026 RHP 20.5 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 Ty Holman TN Christian Brothers 2027 RHP 17.3
2 Tyler Bennett TN CHRISTIAN ACADEMY OF KNOXVILLE 2025 SS 16.7
3 Wyatt Clatur TN Nolensville 2026 RHP 16.7
4 Matt Dill TN The Baylor School 2025 3B 16.0
5 Rhett Slagle TN Elizabethton High School 2026 RHP 15.7

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.”

STRIKE ZONE RATE%

Average MLB pitchers throw 62 percent strikes, and better pitchers throw strikes 65 percent of the time, or a ratio of roughly 2:1, strikes to balls.
