Underclass Trials: Statistical Analysis

Staff Writer, Associate Scout

On Wednesday, June 23, the PBR Wisconsin staff hosted the Underclass Trials, our first showcase of the summer in the Badger State and an annual staple on our calendar. This open event served as an identifier to all members of high school classes 2023-25, serving as an up-close look for future invite-only events, like the PBR Future Games, among others.

We’ll begin our post-event coverage today by breaking down those who stood out from a traditional statistical standpoint inside this stat story. As the week rolls on, we’ll dive deeper into the data gathered by our partners at TrackMan and Blast Motion, so be on the lookout for that.

For now, let’s jump into those who put up noteworthy numbers from this showcase:

+ RHP/OF Sawyer Deering (Kimberly, 2025) fully cemented himself as one of the top names in the state’s incoming freshman class after his performance at this event. We had seen Deering twice already this summer at The Rock, but this up-close look at the future Papermaker helped reassure our previous thoughts. A well-proportioned 5-foot-9, 160-pound athlete, Deering topped at 81 mph from the outfield, the highest mark of the event, with natural carry on his throws to home. He reached an 81 mph high on the mound as well, just missing the event lead of 82 mph by one tick despite being one of the youngest prospects in attendance. The spin characteristics on his fastball and breaking ball, which we’ll highlight in our TrackMan files, make for a rather impressive all-around profile, too.

+ OF Cal Adamczyk (Tremper, 2023) is a quick-twitch 5-foot-8, 135-pound athlete with above-average athleticism and speed for his age. Adamczyk ran the fastest 60-yard dash of the day with a 6.72 and just missed the event lead in max outfield velocity, maxing at 80 mph to home.

+ C Griffin Bowers (Homestead, 2024) looked the part behind the plate during his defensive workout, leading this catcher’s crop in max throwing velocity by topping at 76 mph from the chute. He’s an advanced athlete for his age, running the second-fastest 60-yard dash at 6.80 seconds.

+ OF/RHP Charlie Jackson (Waukesha West, 2023) is a physical 6-foot-3, 200-pound left-handed hitter that oozes projection on the diamond. Jackson moves well for his size, running a 7.03 60-yard dash with athletic strides that cover ground. The Waukesha West sophomore led the event in max exit velocity, barreling one up in his BP round that registered at 95 mph and traveled 359 feet, per TrackMan. He also touched 80 mph on the mound with his fastball.

+ INF/RHP Kyle Alivo (St. Thomas More, 2024) continues to pop up as a follow athlete inside the state’s 2024 class. A high-waisted, projectable athlete, Alivo topped at 85 mph across the infield with natural carry to his throws, showing off a loose, quick arm that can play from multiple arm angles on the move. Alivo’s arm strength translated to the mound, bumping his fastball up to 81 mph.

+ 1B/OF Jason Adix (University School, 2023) has long been on our radar as one of the strongest 2023 graduates in the state. The 6-foot-3, 200-pound right-handed hitting first baseman has plenty of bat strength and physicality attached to his swing, barreling the second-hardest ball of this entire event up at 93 mph.

+ LHP Easton Harris (Middleton, 2025) emerged as a follow name in the state’s incoming freshman class. The 6-foot, 180-pound southpaw touched 77 mph with his fastball, sitting at 74-76 mph from a loose, clean arm. He spun two different breaking balls; a curveball at 2,400+ RPM and a slider at 2,300+ RPM. The projectability paired with his current arsenal make for an intriguing future profile.
