Prep Baseball Scout Day: Phillies Scout Team: Data Dive - Pitchers
June 9, 2024
On May 29th, we traveled Infinite Vision Sports Academy for the Preseason All-State event. This event featured players from the 2025-2027 classes, and it provided our staff with an in-depth look at some high-follow players for the spring high school season. we were excited to some of the top talent across the state as we head into the spring.
Inside today’s Pitching Data dive we will highlight the players with top metrics per Trackman.
Early this week, 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 | Cohen Tyre | GA | Wayne County | 2027 | SS | 83.9 mph |
2 | Hayden Waller | TN | IMG ACADEMY | 2026 | RHP | 83.7 mph |
3 | Cayden Dartez | LA | ST THOMAS MORE HIGH SCHOOL | 2026 | LHP | 82.7 mph |
4 | Dominic Rosa | IL | Midland High School | 2026 | RHP | 79.7 mph |
5 | Pierce Anderson | MS | MADISON RIDGELAND ACADEMY | 2027 | OF | 79.6 mph |
SPIN RATE (AVG.)
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Dominic Rosa | IL | Midland High School | 2026 | RHP | 2079 rpm |
2 | Trevor Alons | NM | CENTENNIAL HIGH SCHOOL | 2028 | 1B | 2006 rpm |
3 | Cayden Dartez | LA | ST THOMAS MORE HIGH SCHOOL | 2026 | LHP | 1924 rpm |
4 | Cohen Tyre | GA | Wayne County | 2027 | SS | 1875 rpm |
5 | Hayden Waller | TN | IMG ACADEMY | 2026 | RHP | 1870 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 | Cayden Dartez | LA | ST THOMAS MORE HIGH SCHOOL | 2026 | LHP | 94 % |
2 | Pierce Anderson | MS | MADISON RIDGELAND ACADEMY | 2027 | OF | 94 % |
3 | Max Raley | SC | Trinity Collegiate | 2027 | 1B | 92 % |
4 | Hayden Waller | TN | IMG ACADEMY | 2026 | RHP | 90 % |
5 | Cohen Tyre | GA | Wayne County | 2027 | SS | 89 % |
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 | Pierce Anderson | MS | MADISON RIDGELAND ACADEMY | 2027 | OF | 19.5 in |
2 | Cayden Dartez | LA | ST THOMAS MORE HIGH SCHOOL | 2026 | LHP | 19.5 in |
3 | Hans Lund | CO | Rock Canyon | 2026 | OF | 18.9 in |
4 | Max Raley | SC | Trinity Collegiate | 2027 | 1B | 16.3 in |
5 | Dominic Rosa | IL | Midland High School | 2026 | RHP | 16.1 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 | Hayden Waller | TN | IMG ACADEMY | 2026 | RHP | 15.0 |
2 | Trevor Alons | NM | CENTENNIAL HIGH SCHOOL | 2028 | 1B | 12.6 |
3 | Cohen Tyre | GA | Wayne County | 2027 | SS | 10.1 |
4 | Max Raley | SC | Trinity Collegiate | 2027 | 1B | 9.9 |
5 | Dominic Rosa | IL | Midland High School | 2026 | RHP | 8.8 |
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.”
