San Antonio Fall ID: Data Dive
November 1, 2023
TEXAS - On 10/1, we made our way to Cornerstone Christian HS for the San Antonio Fall ID. The day consisted of players running the 60, throwing from defensive positions, then taking BP. Both days were capped off with the pitchers throwing bullpens. Today, we take a closer look at the metrics top metrics with the help from our tech partners.

^ | Austin Shreve | TX | Pieper Ranch | 2025 | OF | 66 % |
Sweet Spot percentage: This metric is determined by how often the player produces a batted ball during the session with a launch angle between 8 to 32 degrees.
BLAST MOTION
HAND SPEED (AVG.)
Rank | Name | State | School | Class | Pos | Hand Speed (avg) |
1 | Austin Shreve | TX | Pieper Ranch | 2025 | OF | 21.8 mph |
2 | Nolan Amerman | TX | San Antonio Christian | 2025 | OF | 21.7 mph |
3 | Cameron Benson | MO | SECKMAN SR. HIGH | 2026 | SS | 21.5 mph |
4 | Wyatt Yeatter | TX | Wimberley | 2025 | 3B | 21.5 mph |
5 | Jacob Aguilar | TX | Cornerstone Christian | 2026 | SS | 21.1 mph |
Hand Speed: The observed speed as measured on the handle of the bat (measured six inches from the knob of the bat). Peak Hand Speed will occur prior to the moment of impact, very close to the commit time in the swing when the wrists unhinge.
BAT SPEED (AVG.)
Rank | Name | State | School | Class | Pos | Bat Speed (avg) |
1 | Samuel Miller | TX | Boerne Champion | 2025 | C | 69.3 mph |
2 | Alexander (AJ) Cantu | TX | Harlan | 2024 | C | 69.2 mph |
3 | Roman Grametbauer | TX | HUTTO H S | 2025 | OF | 67.6 mph |
4 | Wyatt Yeatter | TX | Wimberley | 2025 | 3B | 67.4 mph |
5 | Austin Shreve | TX | Pieper Ranch | 2025 | OF | 67.3 mph |
Bat Speed: The observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.
ROTATIONAL ACCELERATION (AVG.)
Rank | Name | State | School | Class | Pos | Rot. Acc (avg) |
1 | Austin Shreve | TX | Pieper Ranch | 2025 | OF | 23.2 g |
2 | Roman Grametbauer | TX | HUTTO H S | 2025 | OF | 18.1 g |
3 | Nolan Amerman | TX | San Antonio Christian | 2025 | OF | 15.0 g |
Body Rotation: A swing that has the appropriate relative contributions of body and bat rotations is an efficient and Powerful swing that maintains proper sequencing. An efficient baseball swing is one in which the body creates the initial movements, which is then transferred to the arms and out to the bat, thereby maximizing Bat Speed through this proximal-to-distal kinematic sequencing movement pattern.

FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Aiden Shreve | TX | Pieper High School | 2026 | RHP | 86.3 mph |
2 | Ethan Armbruster | TX | Westlake High School | 2027 | RHP | 85.2 mph |
3 | Jackson Melanson | TX | BOERNE - SAMUEL V CHAMPION H S | 2025 | RHP | 82.3 mph |
Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.
INDUCED VERTICAL BREAK (AVG.)
Rank | Name | State | School | Class | Pos | IVB (avg) |
1 | Ethan Armbruster | TX | Westlake High School | 2027 | RHP | 15.2 in |
2 | Cameron Benson | MO | SECKMAN SR. HIGH | 2026 | SS | 14.9 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 | Jackson Melanson | TX | BOERNE - SAMUEL V CHAMPION H S | 2025 | RHP | 15.7 |
2 | Matthew Heredia | TX | Liberty Christian School | 2028 | SS | 14.5 |
3 | Reed Blumhoff | TX | Clemens | 2025 | RHP | 13.0 |
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.”
