Dallas Preseason ID: Pitcher Data Dive


By: Tyler Defibaugh
Texas Staff

On Sunday, January 12th, the PB Texas staff traveled to NTXBC - Indoor Facility in Keller, TX, to host the Dallas Preseason ID, an open event for the class of 2025-2028.

Players participated in a pro-style workout, gathering unrivaled access to data through our state-of-the-art tech partners, as well as in-depth scouting analysis from our Prep Baseball Texas staff.

We've already posted a Statistical Analysis from the event, highlighting more of the traditional statistical categories, as well as a Takeaways, highlighting some of the events top performers. We also highlighted some of the top positional players within this Data Dive story.

Today, we will be looking at the top measurable data performers from the event, found below.

FASTBALL

VELOCITY (MAX)

Rank Name State School Class Pos Velocity (max)
1 Landon Bertucci TX Rowlett 2025 RHP 87.2 mph
2 Kellan McWhinnie TX Plano East 2027 RHP 84.7 mph
3 Aiden Wright TX Plano 2027 RHP 81.0 mph

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Landon Bertucci TX Rowlett 2025 RHP 2170 rpm
2 Nathan Tomkins TX Southlake Carroll 2028 OF 1997 rpm
3 Aiden Wright TX Plano 2027 RHP 1973 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 Nathan Tomkins TX Southlake Carroll 2028 OF 20.0 in
2 Aiden Wright TX Plano 2027 RHP 18.6 in
3 Michael Maggart TX South Grand Prairie 2028 3B 17.5 in
4 Nash Westerfeld Thomas TX Rock Hill 2026 LHP 16.4 in
5 Landon Bertucci TX Rowlett 2025 RHP 16.4 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 efficiencies. 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 vertical approach angle.

HORIZONTAL MOVEMENT (AVG.)

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.”

STRIKE ZONE RATE%

Rank Name State School Class Pos Zone %
1 Ethan Downing TX Bells 2027 LHP 55 %
^ Michael Maggart TX South Grand Prairie 2028 3B 55 %
2 Nash Westerfeld Thomas TX Rock Hill 2026 LHP 54 %
3 Kellan McWhinnie TX Plano East 2027 RHP 50 %
^ Charlie Kulak TX Southlake Carroll 2027 1B 50 %

 Average MLB pitchers throw 62% strikes, and better pitchers throw strikes 65% of the time, or roughly 2:1 strikes to balls.
