Mid-South Preseason ID: Data Dive, Pitchers
February 6, 2024
COLLIERVILLE, TN - The Mid-South Preseason ID was held on Saturday, January 27th at Collierville High School's Indoor Facility. This event was an open event that consisted of players from the 2024-2028 classes from 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. 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 back at the top data and metrics from the event.
FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Lance Bryan | TN | Briarcrest Christian | 2025 | RHP | 90.4 mph |
2 | Ridge Harvey | TN | Collierville | 2025 | LHP | 86.5 mph |
3 | Caleb Doty | TN | Lausanne Collegiate | 2025 | 3B | 85.4 mph |
4 | Ty Holman | TN | Christian Brothers High School | 2027 | SS | 83.8 mph |
5 | Bradley Stubbs | TN | Collierville | 2026 | SS | 83.2 mph |
SPIN RATE (AVG.)
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Lance Bryan | TN | Briarcrest Christian | 2025 | RHP | 2448 rpm |
2 | Ridge Harvey | TN | Collierville | 2025 | LHP | 2246 rpm |
3 | Hunter Harkness | TN | Tipton-Rosemark Academy | 2025 | RHP | 2173 rpm |
4 | Ty Holman | TN | Christian Brothers High School | 2027 | SS | 2067 rpm |
5 | Hudson Rushing | TN | UNIVERSITY SCHOOL OF JACKSON | 2027 | OF | 2056 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 | Jett Gassid | TN | Collierville | 2027 | SS | 98 % |
2 | Ty Holman | TN | Christian Brothers High School | 2027 | SS | 95 % |
3 | Bradley Stubbs | TN | Collierville | 2026 | SS | 92 % |
4 | Conner Palmer | TN | Collierville | 2026 | 1B | 91 % |
5 | Caleb Doty | TN | Lausanne Collegiate | 2025 | 3B | 90 % |
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 | Conner Palmer | TN | Collierville | 2026 | 1B | 20.6 in |
2 | Jett Gassid | TN | Collierville | 2027 | SS | 19.9 in |
3 | Bradley Stubbs | TN | Collierville | 2026 | SS | 19.5 in |
4 | Lance Bryan | TN | Briarcrest Christian | 2025 | RHP | 19.3 in |
5 | Caleb Doty | TN | Lausanne Collegiate | 2025 | 3B | 18.8 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 High School | 2027 | SS | 18.4 |
2 | Ian Chambers | TN | Collierville | 2025 | OF | 14.3 |
3 | Chase Armistead | TN | Collierville | 2027 | RHP | 12.1 |
4 | Lance Bryan | TN | Briarcrest Christian | 2025 | RHP | 10.4 |
5 | Conner Palmer | TN | Collierville | 2026 | 1B | 9.6 |
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.
