Zachary, LA - On Tuesday, July 1, 2025, the Prep Baseball Louisiana staff traveled to the Zachary Youth Park, to host the final rising stars event on our summer calendar, which featured 20 players in the 2029-2030 classes.  Each participant went through a pro-style workout that consisted of running a laser-timed 60 yard dash using Vald Performance, defensive evaluations, and batting practice using Trackman Baseball.  Each pitcher also threw a bullpen with Trackman Baseball to receive all of their data and metrics.  Below, we take a look at the top Trackman pitching metrics and data from Tuesday's event.

AVERAGE FASTBALL SPIN RATE

RANK	NAME	STATE	SCHOOL	CLASS	POS	SPIN RATE
1	Jackson Coffey	LA	Calvary Baptist Academy	2030	LHP	2,046 RPM
2	Leyton Anthony	LA	Catholic-New Iberia	2029	OF	1,993 RPM
3	Kellan Brian	LA	Catholic High School of Baton Rouge	2029	OF	1,979 RPM
4	Tate Underwood	LA	Benton	2029	SS	1,850 RPM
5	Kohner Johnson	LA	Scott Middle School	2030	1B	1,794 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.

 

AVERAGE FASTBALL HORIZONTAL MOVEMENT

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.”

AVERAGE FASTBALL INDUCED VERTICAL BREAK

RANK	NAME	STATE	SCHOOL	CLASS	POS	IVB (AVG.)
1	Leyton Anthony	LA	Catholic-New Iberia	2029	OF	19.1
2	Tate Underwood	LA	Benton	2029	SS	17.7
3	Kohner Johnson	LA	Scott Middle School	2030	1B	14.8
4	Myles Donaldson	LA	St. Michael's	2029	3B	14.4
5	Jackson Coffey	LA	Calvary Baptist Academy	2030	LHP	11.4

Induced Vertical Break: IVB simply means the pitch is "breaking" upward from the average level a pitch falls from release to home plate.  The higher the number, the more "rise" the pitch has compared to average. 

AVERAGE SLIDER SPIN RATE

RANK	NAME	STATE	SCHOOL	CLASS	POS	SPIN RATE
1	Chandler Parker	LA	Doyle	2029	SS	2,492 RPM
2	Jackson Coffey	LA	Calvary Baptist Academy	2030	LHP	2,270 RPM

Spin Rate: The metric calculates how fast the ball is spinning as it leaves the pitcher’s hand, reported in the number of times the pitched ball would spin per minute (“revolutions per minute” or “rpm”).

 

AVERAGE CURVEBALL SPIN RATE

RANK	NAME	STATE	SCHOOL	CLASS	POS	SPIN RATE
1	Chandler Parker	LA	Doyle	2029	SS	2,394 RPM
2	Kohner Johnson	LA	Scott Middle School	2030	1B	2,268 RPM
3	Jackson Coffey	LA	Calvary Baptist Academy	2030	LHP	2,065 RPM
4	Kellan Brian	LA	Catholic High School of Baton Rouge	2029	OF	1,925 RPM
5	John Hamilton	LA	West Feliciana	2029	RHP	1,874 RPM

Spin Rate: The metric calculates how fast the ball is spinning as it leaves the pitcher’s hand, reported in the number of times the pitched ball would spin per minute (“revolutions per minute” or “rpm”).

 

AVERAGE CHANGEUP HORIZONTAL MOVEMENT

Horizontal Break: This metric measures the distance, 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.
