Area Scout, Illinois & Missouri

On Wednesday, June 15, the PBR Illinois and PBR Missouri staffs collaborated to host the annual St. Louis Open at the Billiken Sports Center on the campus of Saint Louis University. This event regularly allows both us an opportunity to check in on players from the Greater Metro region, including prospects that attend from central and southern Illinois.

To see which players attended, as well as all of the statistics from this event, click HERE.

We recently rolled out the Stat Story from this event, highlighting which players found themselves atop the leaderboards from this event. Today, with the help of our tech partners, we'll dive deeper into the numbers collected by analyzing the pitch metrics and batted ball data captured throughout the day.

Read below to see which prospects' popped from a data standpoint on our TrackMan units.

MAX FASTBALL & PEAK SPIN RATE

Rank Name State School Class Pos Velocity (max)
1 Ronnie Willenbrink MO Affton 2023 RHP 86.6 mph
2 Henry Kufa IL Carlinville 2023 SS 83.1 mph
3 Cole Evans MO Timberland 2023 RHP 82.9 mph

8 Grainger Yurevich IL Woodland, MO 2023 1B 80.0 mph
9 John Hilpert IL Belleville West 2025 OF 79.7 mph
10 Tommy Kramkowski IL Belleville East 2025 RHP 79.5 mph

Rank Name State School Class Pos Spin Rate (max)
1 Ronnie Willenbrink MO Affton 2023 RHP 2236 rpm
2 Zack Boland MO Parkway West 2023 LHP 2184 rpm
3 Tommy Kramkowski IL Belleville East 2025 RHP 2154 rpm
4 Henry Kufa IL Carlinville 2023 SS 2139 rpm

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

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

Rank Name State School Class Pos HM (avg)
1 Ronnie Willenbrink MO Affton 2023 RHP 18.2
2 Reiss Beahan MO Columbia Hickman 2023 LHP -11.9
3 Drew Messey MO Westminster Christian 2026 SS 11.5

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.”
