What happened: The Cincinnati Reds are designating Rows L-Y in sections 401-406 of the Kroger Bleachers as the dedicated "Tarps Off" 3-2-1 Tuesday Sections during Tuesday home games at Great American Ball Park. The club says any fan in the ballpark, regardless of where their seat is located, can move into the area to take part. It is being positioned as a high-energy gathering spot for supporters.

Why it matters: Concentrating engaged fans into a single bleacher zone gives the Reds a built-in atmosphere booster on weeknight home dates, when crowds can run lighter. Opening the section to anyone in the building lowers the barrier for casual attendees to join the most vocal part of the park, which can lift the in-stadium experience and the home-field feel.

What to watch: Watch how the section fills on the next Tuesday home date and whether the Reds expand the format to other weeknights if turnout in the Kroger Bleachers responds.
