West Suburban Open: Position Player Analysis


By: Illinois Scouting Staff

On Tuesday, June 28, the PBR Illinois staff hosted the West Suburban Open at Lee Pfund Stadium in Carol Stream, Illinois. The event hosted 30 players ranging from the 2023-2026 grad classes and provided our staff an in-depth look at all prospects in attendance. Despite being one of the smaller events of the summer, this open event was jam-packed with talent - with two participants eventually landing spots on Team Illinois for the Future Games and a few others garnering invites to the Illinois State Games

In the week that followed this event, we produced a post-event analysis that includes performance highlights inside of our Quick Hits story, a look at the batted-ball and pitch data compiled in TrackMan Files, swing metrics captured on the Blast Motion Board, and sight scores from an athletic perspective tracked on the Vizual Edge Scoreboard.

You can learn more about the state-of-the-art technologies featured at our showcases within the hyperlinks above. Today we’ll begin our post-event process by rolling out the individual scouting reports of the day, starting with the position players.
