The St. Louis Cardinals have embraced the 'Tarps Off' fan movement, officially dedicating the upper right-field bleachers to high-energy supporters starting May 21, 2026. What began as an organic surge of enthusiasm—led by shirtless Stephen F. Austin college baseball players during a visit to Busch Stadium—has become a sanctioned part of the game-day experience. Fans from all over the stadium are now welcome to join the section, regardless of their original seat location.

The movement gained momentum during a May 16 game against the Kansas City Royals, when the 17 visiting players ignited a wave of cheering and shirt-waving that spread through the crowd. The energy coincided with a walk-off single by Yohel Pozo, and manager Oliver Marmol later praised the atmosphere, even offering to buy tickets for future participants. The section remained electric in subsequent games, including a walk-off home run by Ivan Herrera on May 20.

Though the Cardinals were expected to be in rebuild mode in 2026, they’ve surged to a 28-19 record and second place in the NL Central. The 'Tarps Off' phenomenon has since inspired similar fan sections in Detroit, Tampa Bay, Philadelphia, Seattle, and Anaheim, signaling a potential cultural shift in how fans engage with MLB games.
