Hattiesburg Summer ID: Data Dive, Pitchers
July 12, 2024
HATTIESBURG, MS - The Hattiesburg Summer ID was held on July 2nd at Pete Taylor Park on the campus of Southern Miss in Hattiesburg, MS. This event was an open event that consisted of some prospects from the 2025-2028 classes across all parts of Mississippi. These players went through extended pro-style workout that included batting practice using Trackman, and much more. Pitchers were able to throw simulated innings during gameplay and were able to get numbers and metrics via 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 at some of the standouts from the Hattiesburg Summer ID. Below, you can find an in depth look at the data and metrics on the pitchers from the event.

FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Landry Winter | MS | EUPORA HIGH SCHOOL | 2025 | RHP | 89.0 mph |
2 | Cooper Rayburn | MS | Jackson Academy | 2025 | RHP | 87.2 mph |
3 | Konnor Cazenave | MS | Pearl River Central | 2025 | RHP | 85.7 mph |
4 | Dominic Smith | MS | North Pike | 2025 | RHP | 84.9 mph |
5 | Dylan Varnell | MS | Northwest Rankin | 2026 | OF | 84.3 mph |
SPIN RATE (AVG.)
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Asher Cox | MS | Madison Ridgeland Academy | 2028 | 2B | 2133 rpm |
2 | Cooper McCoy | MS | Sumrall High School | 2028 | 3B | 2109 rpm |
3 | Maddox Perry | MS | Germantown | 2027 | SS | 2105 rpm |
4 | Carson Philyaw | MS | Kosciusko | 2026 | 3B | 2098 rpm |
5 | Konnor Cazenave | MS | Pearl River Central | 2025 | RHP | 2091 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 | Latham Bynum | MS | Hartfield Academy | 2026 | RHP | 97 % |
2 | Duane Dantzler | MS | North Forrest | 2027 | 2B | 97 % |
3 | Rush Watkins | MS | Baldwyn | 2027 | RHP | 96 % |
4 | Bryce Bailey | MS | Sumrall | 2028 | 2B | 94 % |
5 | Asher Cox | MS | Madison Ridgeland Academy | 2028 | 2B | 92 % |
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 | Latham Bynum | MS | Hartfield Academy | 2026 | RHP | 18.9 in |
2 | Carson Philyaw | MS | Kosciusko | 2026 | 3B | 17.7 in |
3 | Asher Cox | MS | Madison Ridgeland Academy | 2028 | 2B | 17.5 in |
4 | Kadan Sahler | MS | Madison Ridgeland Academy | 2025 | LHP | 16.6 in |
5 | Rush Watkins | MS | Baldwyn | 2027 | RHP | 16.2 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 | Rush Watkins | MS | Baldwyn | 2027 | RHP | 16.1 |
2 | Landry Winter | MS | EUPORA HIGH SCHOOL | 2025 | RHP | 15.5 |
3 | Asher Cox | MS | Madison Ridgeland Academy | 2028 | 2B | 14.2 |
4 | Chad Davidson | MS | St. Joseph Catholic | 2027 | LHP | -13.4 |
5 | Carson Philyaw | MS | Kosciusko | 2026 | 3B | 12.6 |
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.”
