Underclass Fall Invite: TrackMan Files


PBR Washington Staff

On September 3rd the PBR Washington staff hosted the Underclass Fall Invite at Bannerwood Sports Park, featuring many of the state’s top players inside the 2025-2026 classes. Inside today’s TrackMan Files, we’re highlighting the top performers from this event from the data and metrics from our TrackMan unit.

Earlier this week we published Quick Hits highlighting the top prospects of the event. We also rolled out a Statistical Leaderboard pointing out the top recorded stats by category.

Now we'll continue to roll out the data we gathered from this event, starting with the analytics we have at our disposal from our TrackMan unit. Below we'll look at which players had noteworthy batted ball and pitch metric data.

MAX FASTBALL

RANK   NAME STATE SCHOOL CLASS POS VELOCITY (MAX)
1 Cooper Markham    WA Enumclaw 2025 RHP 86.0 mph
2 Christopher Moore WA Kentlake 2026 SS 82.4 mph
3 Preston Przybylski WA Mount Si 2025 C 80.8 mph
4 Jonah Aase WA Meridian 2025 LHP 80.7 mph
5 Jake McCall WA West Seattle 2026 RHP 79.4 mph
6 McCrea Curfman WA Bainbridge 2026 RHP 79.1 mph

 

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

PEAK SPIN RATE

RANK   NAME STATE SCHOOL CLASS POS SPIN RATE (MAX)
1 Cooper Markham  WA Enumclaw 2025 RHP 2534 rpm
2 Luke Doman WA Glacier Peak 2025 SS 2432 rpm
3 Jake McCall WA West Seattle 2026 RHP 2323 rpm
4 McCrea Curfman WA Bainbridge 2026 RHP 2307 rpm
5 Jonah Aase WA Meridian 2025 LHP 2205 rpm
6 Khing Ljutic WA Seattle Prep 2026 RHP 2203 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.
