Future Game Testing: JAX – Data Analysis

On Tuesday, July 2, the Future Games Trials: JAX took place at the University of North Florida in Jacksonville, Florida. The event featured players from the classes of 2025-2028 who participated in a pro-style workout followed by bullpen sessions in front of the Prep Baseball Florida scouting staff.

In today’s Data Dive, we’ll be highlighting the players with the best metrics according to Trackman, Blast, and Swift.

On Wednesday, we broke down the stats leaders in the more traditional categories on our statistical leaderboards. Today, we’ll take a closer look at the players present with the help of our technology partners, broken down by category and leaderboard below.

Pitchers

MAXIMUM SPEED (MPH)

SPINNING SPEED (AVERAGE)

Turning speed: This metric calculates the spin rate of the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs reduce the impact of gravity, allowing for more “lift” (or less drop, in other words) as it travels through the zone. Low-spin fastballs generally indicate that the pitch has more horizontal action, often making it harder to square up but generally easier to make contact with, leading to more balls on the ground, while high-spin fastballs show a correlation with swings and misses.

SPINNING EFFICIENCY % (AVERAGE)

Spin efficiency: This metric is the percentage of raw spin rate that directly affects the movement of the pitch; therefore, while raw spin is measured in revolutions per minute (rpm), spin efficiency is the ratio of actual spin divided by raw spin. It is important to understand that more is not always better when it comes to spin efficiency. Optimal spin efficiency on a pitch depends on the type of pitch and must be understood in the context of a pitcher’s entire arsenal. With respect to the true four-seam fastball, near 100 percent spin efficiency is preferable, indicating that nearly all of the backspin generated on the ball as it leaves the pitcher’s hand contributes to the “traveling” 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 BREAKAGE (AVERAGE)

Induced vertical breakage: Used in shorthand as “IVB,” this metric is most important on fastballs to create lift and on curveballs to create depth; it can also have some use when measuring sliders and cutters. Sliders tend to be closer to zero inches, while cutters are usually between 5 and 15 inches. Typically, fastballs and curveballs with large IVB also have higher spin efficiencies. Sliders typically have very little (close to zero) IVB and very low spin efficiency. You could also categorize IVB under spin rate, as this is part of the “useful movement” you’re looking for. IVB is also a big part of vertical approach angle.

HORIZONTAL MOVEMENT (AVERAGE)

Horizontal break: As described on the TrackMan website: “…horizontal movement is measured in inches between the point at which the pitch crosses the front of home plate sideways and the point at which it would have crossed sideways if it had followed a perfectly straight line from the time of delivery. 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.”

SPINNING SPEED (AVERAGE)

INDUCED VERTICAL BREAKAGE (AVERAGE)

HORIZONTAL MOVEMENT (AVERAGE)

SPINNING SPEED (AVERAGE)

1 Lord of Denton Florida SOUTH WALTON HIGH SCHOOL 2026 Fast pitcher

1830 rpm

2 Kyle Hopper Florida THE FIRST ACADEMY 2025 Fast pitcher

1154 rpm

HORIZONTAL MOVEMENT (AVERAGE)

Batters

60 YARD DASH


OUTPUT SPEED (MAXIMUM)

EXIT SPEED (AVERAGE)

Exit velocity:This metric measures the speed of the ball, measured in miles per hour, as it leaves the bat at the moment of contact.

DISTANCE OF BATTED BALL (MAXIMUM)

FAIR POINT%

Optimal point percentage:This metric is determined by how often the player produces a batted ball during the session with a launch angle between 8 and 32 degrees.


HAND SPEED (AVERAGE)

Hand speed:Observed speed, measured at the bat handle (six inches from the bat handle). Peak hand speed occurs before the moment of impact, very close to the moment of engagement in the swing when the wrists are unhinged.

BAT SPEED (AVERAGE)

Bat speed:The velocity observed at the sweet spot of the bat at the moment of impact. The sweet spot of the bat is measured six inches from the tip of the bat.

ROTATIONAL ACCELERATION (AVG.)

Rotational acceleration:Spin measures how quickly the bat accelerates through the swing plane. Spin is a good indicator of how bat speed is increased by performing the correct sequence rather than pulling the bat with your hands. The faster the rotational acceleration, the more power you have and the more time you have to make a decision at the plate.
