With our 2026 event calendar on the horizon, our staff has dedicated some time to reflect on the top statistical performers that we saw at our events in 2025. We'll be shining some light on Wisconsin natives who put up loud numbers in 2025, showcasing their tools to our staff at Prep Baseball Wisconsin events.

These leaderboards were compiled solely based on numbers at our state events, including Super 60, Preseason IDs, All-States, Open events, Future Games, and the All-American Game, too.
