IL/WI Underclass Games: Catcher Analysis

By: Illinois Scouting Staff

On Tuesday, July 20, the PBR Illinois staff hosted the Underclass Games at Triton College in River Grove. The invite-only event featured some of the top players from Illinois and Wisconsin in the Class of 2024. A number of high-level follows emerged at the event and many will be names to become familiar with as they enter their sophomore year of high school.

Our staff published several pieces shortly after the event’s conclusion and you can find those by clicking HERE. 

Today we’ll begin rolling out our position-by-position analysis from the day, starting with the catchers and working our way around the diamond throughout the week. Here is a quick nugget on each: 

+ Listed at 5-foot-8 178-pounds, Cal Casper (Bay Port; WI) has a lean and athletic build with wiry strength. The right-handed hitter showed some high level ability with his barrel to ball talent. His swing is loose, short and quick. He peppered the outfield with line drives during his round of batting practice. His top exit velocity was 90 mph per Trackman. Casper’s high level abilities showed on defense as well, starting with his above-average arm strength. His exchange and footwork are advanced behind the plate and out at shortstop. His top pop time was 2.05. Casper emerged as versatile, athletic 2024 to follow moving forward.

+ Seth Impson (Springfield) is 5-foot-10, 155-pounds of energy. Impson was active and loud the entire day no matter where he was on the field, coaching up teammates and handling himself with confidence. Impson also backed up his innate catcher profile with highly-advanced actions, playing quick and athletic out of the crouch. Impson’s pop times ranged from 2.01-2.09.  His throws have carry and were consistently on the bag. Impson is advanced beyond his years behind the plate.  

Ryan Dummer (Burlington; WI) is right-handed hitting catcher that flashed advanced bat speed during batting practice, utilizing a loose, short, and quick swing to produce line drive contact throughout his round of BP while reaching a peak exit velocity of 93.40 mph. 

+ Another Wisconsin native, Joshua Gilroy (Arrowhead; WI) displayed some of the day’s top raw power. Both Gilroy’s hardest hit ball (97 mph) and farthest hit ball (372 ft.) were amongst the highest numbers we saw at the event. There’s certainly a power-driven ceiling attached to the 6-foot, 180-pound Gilroy’s right-handed bat.
