Tucson Preseason ID: Pitching Data Dive

On Saturday, January 20th, the PBR Arizona staff hosted it's second Preseason ID of the month with the Tucson Preseason ID at Kino Sports Complex in Tucson, Arizona. This event featured 14 prospects from the 2024 - 2028 classes and allowed our staff an opportunity to get an in-depth look and analysis of the players in attendance.

Earlier this week, we broke down the top measurable data performers from the event with our Statistical Analysis article. Now, we will take a further in-depth look at the top pitchers with the help of our tech partnerships, broken down by the categories down below:

FASTBALL

MAX VELOCITY (MPH)

Rank Name State School Class Pos Velocity (max)
1 Kash Espinosa AZ Salpointe Catholic 2026 RHP 75.9 mph
2 William (Austin) Feurstock AZ Ironwood Ridge 2026 SS 73.4 mph
3 Tanner Sultan AZ Catalina Foothills High School 2028 SS 72.0 mph
4 Christopher Bennett NM Silver 2025 C 67.2 mph

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

SPIN RATE (AVG)

Rank Name State School Class Pos Spin Rate (avg)
1 Kash Espinosa AZ Salpointe Catholic 2026 RHP 1992 rpm
2 William (Austin) Feurstock AZ Ironwood Ridge 2026 SS 1940 rpm
3 Christopher Bennett NM Silver 2025 C 1849 rpm
4 Tanner Sultan AZ Catalina Foothills High School 2028 SS 1784 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.

INDUCED VERTICAL BREAK (AVG.)

Rank Name State School Class Pos IVB (avg)
1 Kash Espinosa AZ Salpointe Catholic 2026 RHP 18.3 in
2 Christopher Bennett NM Silver 2025 C 14.2 in
3 Tanner Sultan AZ Catalina Foothills High School 2028 SS 10.6 in
4 William (Austin) Feurstock AZ Ironwood Ridge 2026 SS 6.8 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 Tanner Sultan AZ Catalina Foothills High School 2028 SS 13.6
2 Kash Espinosa AZ Salpointe Catholic 2026 RHP 11.4
3 William (Austin) Feurstock AZ Ironwood Ridge 2026 SS 9.9
4 Christopher Bennett NM Silver 2025 C 1.2

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.”
