South Milwaukee Preseason ID: Top Overall Prospects

Wisconsin Staff

On Sunday, March 3rd, the Prep Baseball Wisconsin staff traveled to the Hitters facility in Caledonia, WI to host one of the largest showcases on our winter calendar, the South Milwaukee Preseason ID. This event provided us an ample opportunity to check-in on some of the area’s high school prospects and identify several names as we prepare for the WIAA season, as well as future invite-only events on the PBR Wisconsin calendar.

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 covered in our Positional and Pitcher data dives.

You can learn more about the state-of-the-art technologies featured at our showcases within the hyperlinks above. Today we’ll conclude our post-event process by rolling out the individual scouting reports of the day, continuing top overall prospects that were in attendance.
