The Illinois high school baseball season kicks off on March 13, opening day for regular season action under IHSA regulations. Leading up to opening day, we're publishing our team previews ahead of the 2023 spring season, touching on programs spanning all state classifications, counting down through the official PBR Illinois Preseason Power 25 Rankings.
After Opening Day, our scouts will be out and about covering the 2023 season, publishing scout notes and additional in-season content along the way, like Power 25 updates, Player of the Week awards, and weekly top performers included inside Diamond Notes.
Follow along throughout the spring season by following us on Twitter @PBRIllinois.
