Missouri Summer Data Dive: Pitchers

By: Diego Solares
Area Scout, Illinois & Missouri

As we begin to wrap up the summer circuit and transition towards our fall schedule, we’re taking the time to reflect on players that have impressed us over the past three months at our events.

A main component of what we offer at a PBR Showcase is unrivaled access to underlying data captured through the devices provided via our tech partners. To learn more about all of this information, including how it’s captured and what it means, click HERE.

We began our ‘Data Dive’ late last week by looking at position players who put up noteworthy metrics at our events throughout the summer, which you can find HERE. Today, we’ll turn to the pitching side and analyze prospects who’s TrackMan data popped upon further review, which you can find below. 


+ At 6-foot-3, 175-pounds, RHP Tyler Holman (Liberty, 2024) provided not only an upside physical look at our June event, but an analytical one, too. Holman’s fastball sat at 83-86 mph, peaking at 87 mph, with 2,334 RPM and 20+ inches of vertical carry on average, respectively.

+ Another high-follow arm in the state’s 2025 class is C/RHP JD Dohrmann (Vianney). The 6-foot, 180-pound right-hander pumped his fastball in the low-80s at this event, touching 84 mph and hitting higher marks in our looks across the summer. Dohrmann’s pitch data on his off-speed, however, is the separator for him. His curveball averaged 2,400+ RPM per pitch at 69-72 mph, peaking at 2,535 RPM. Though he used it minimally, Dohrmann’s 72-75 mph changeup flashed intrigue, peaking at 20 inches of horizontal movement with little-to-no lift, which is ideal for the pitch. Dohrmann is someone we’re eager to see throughout the fall and early into next year.


+ RHP Ronnie Willenbrink (Affton, 2023) piqued our interest during his ‘pen at the St. Louis Open. At 5-foot-10, 165-pounds, Willenbrink ripped off a lively 85-87 mph fastball throughout from a lower average arm slot (4.7 ft.) with 18.2 inches of vertical carry, per TrackMan. Willenbrink generated natural raw spin on his 68-70 mph breaking ball, topping at 2,527 RPM with a 2,362 RPM average.


+ At 84-86 mph, RHP Connor McCaleb’s (Timberland, 2023) fastball jumped out of his hand through two innings of work at the St. Louis Top Prospect Games. His heater topped at 23 inches of vertical carry, averaging 18.9 inches, while also peaking at 2,441 RPM. Still uncommitted, the 6-foot-1, 190-pound McCaleb is amongst the top arms available in Missouri’s incoming senior class.

+ One of the first arms to toe the rubber at this event, SS/RHP Mason Beno (Parkway West, 2024) stole the show early. At 5-foot-11, 165-pounds, Beno’s aptitude to spin may be his most redeeming attribute. He ripped off a 74-76 mph slider with conviction from a lower arm slot (4.5 ft.) at 2,469 RPM on average, topping 2,598 RPM during his outing. Beno owns a lively fastball as well, running his heater up to 88 mph in this look.


+ Perhaps the loudest pure stuff we saw this summer came from RHP Denton Biller (Mid Buchanan, 2023; Johnson County CC) at this event. The 6-foot-3, 182-pound Biller pumped low-90s heat with his fastball, averaging 2,466 RPM with a max of 2,571 RPM. Biller’s arm speed helped him generate pure raw spin on his slider, a pitch that topped at 2,636 RPM, spinning at 2,480 RPM on average.

+ One of the top seniors left on the market, RHP Simon Linde (Liberty, 2023) impressed our scouts across multiple looks throughout the summer, including at this event. At 6-foot-1, 190-pounds, Linde’s fastball sat 86-88 mph, but his natural ability to spin a slider at an advanced rate is the separator. He ripped off a hard-biting, late sweeper at 74-77 mph with 17 inches of horizontal movement and 2,564 RPM on average, too.

+ The ability to spin a breaking ball at a high rate tends to be an indicator of future velocity to come, and RHP Jake Thomas (Staley) may be a member of the state’s 2025 class that fits that bill. Currently pumping his fastball in the low-80s, the 6-foot, 155-pound incoming sophomore spun a low-to-mid-70s breaking ball at 2,448 RPM per pitch, peaking at 2,602 RPM.
