Wisconsin Underclass Trials: Pitcher Analysis


By Wisconsin Staff

On June 24, the PBR Wisconsin team started its hefty summer showcase circuit with its annual Underclass Trials event, a showcase targeted for prospects representing graduating classes of 2022, 2023, and 2024. We produced our rapid post-event analysis in the days that followed, inside our Quick Hits and Statistical Analysis posts, and we’re wrapping up our event analysis this week having written scouting reports on each of the event’s prospects.

We began our position-by-position analysis with the event’s catchers, outfielders, and infielders, and we’re onto this big list of pitchers today.

Landing a spot atop this group is 2023 righty Cole Selvig (Regis). He has some prominent arm strength for someone his age, and he utilizes a couple upside offspeed pitches within his arsenal. He also showed a feel to locate all three at this event, too, demonstrating a follow profile within the state’s 2023 class of arms.

Big junior righty Chase Ignatius (Barnevald) has impressed in multiple live looks and he substantiated those performances with this up-close look. Inside a durable, strong build, Ignatius throws a heavy fastball that was up to 85 mph, and he complements it with a changeup that features some hard sinking action. Fellow junior Mason Krznarich (Arrowhead) has a really loose, live arm with big extension that helps his mid-80s velo play up.

Check out their scouting reports in full below, as well as the rest of the pitchers who took reps at this event back in June.
