Chicago Preseason ID: Pitcher Analysis


By: Illinois Scouting Staff

On Feb. 19, the PBR Illinois staff traveled to the Pullman Community Center in Chicago to host the Chicago Preseason ID. This event provided us an ample opportunity to check-in on some of the area’s top high school prospects and identify several new names to know as we prepare for the IHSA season, as well as future invite-only events on the PBR Illinois calendar, like Saturday’s Preseason All-State events.

In the week that followed this event, we produced post-event analysis that includes performance highlights inside of our Quick Hits story, a look at the traditional stats measured within our Statistical Analysis piece, 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. We began our position-by-position scouting reports process last week with the catching group and followed it up with the outfielders. The position player analysis was concluded shortly afterwards with the event’s infielders and we’ll wrap things up today with the event’s pitchers - found below.
