“Tarps Off” Shirtless Fan Wave Sweeps Major League Baseball
5/23/2026, 1:15:36 PM
The Phenomenon Takes Hold in MLB
In early May 2026 a group of Stephen F. Austin State University club-baseball players removed their shirts in the right-field bleachers of Busch Stadium during a Cardinals-Royals game. The act sparked a spontaneous wave of shirtless fans that coincided with a 5-4, 11-inning walk-off win. Within days the movement spread to other sections of Busch, to the Cardinals’ clubhouse, and then to ballparks in Detroit, Seattle, Tampa Bay, Philadelphia, Anaheim and beyond.
Origin and Early Context
The practice traces to an October 2025 college-football bet at an Oklahoma State game, where a fan stripped and twirled his shirt. The gesture migrated to college baseball and, according to multiple reports, found its first major-league foothold when the Stephen F. Austin team attended the May 9 Cardinals-Royals contest.
Key Figures and Groups
- Stephen F. Austin club baseball team – the initial participants, including Bryce Bradford, who declared “Screw it. I’ll do it.”
- Oliver Marmol – Cardinals manager who bought tickets for the shirtless revelers and publicly pledged continued support.
- Masyn Winn – Cardinals shortstop who noted the fan energy.
- Chad Bitzer – Seattle fan who described the night as “fresh… a beautiful night. Take it off.”
- Pete Nesbit – Senior vice president of ballpark operations for the Red Sox, who clarified the lack of a formal policy against shirt removal.
Timeline of Major Moments
- Oct 2025 – Shirt-off bet at Oklahoma State football game.
- May 9 2026 – Stephen F. Austin players strip at Busch Stadium; Cardinals win 5-4 in 11 innings.
- May 15 2026 – Cardinals beat Royals again; Marmol purchases a full right-field section for shirtless fans.
- May 16-20 2026 – Cardinals designate a permanent “high-energy” section; the trend appears at Detroit’s Comerica Park, Seattle’s T-Mobile Park, Tampa Bay’s Tropicana Field, and other venues.
- May 21 2026 – MLB reports a season-average attendance increase of roughly 1,000 fans per game, with projections of 30,000 per game if the trend persists.
Data and Statistics
- Attendance up ? 1,000 fans per game league-wide (MLB).
- Projected average attendance could reach 30,000 per game, the highest since 2016.
- Shirtless sections have appeared in at least eight ballparks within two weeks.
Why It Matters
League officials and team executives cite the movement as a boost to stadium atmosphere and a potential tool for attracting younger fans. The Cardinals’ home-field advantage appears enhanced, with Ivan Herrera’s three-run walk-off homer on May 20 linked to the energized crowd.
Official Statements & Responses
- Marmol emphasized the “fun environment” and expressed interest in making the fan section a regular feature.
- Winn praised the fans, noting the “best fans in the world” and the college-like atmosphere.
- Nesbit confirmed Fenway has no specific rule prohibiting shirt removal, urging fans to follow the code of conduct.
- MLB representatives described the trend as “loud, goofy, infectious and new to the baseball world.”
Criticism & Opposition
Some observers warn the craze may become “too tired, too contrived, too 2025,” suggesting the novelty could wear thin if over-commercialized. No formal league opposition has been recorded, but the sentiment reflects a cautious view of its longevity.
On-the-Ground Reports
Fans such as Bitzer in Seattle and local attendees in Detroit described the experience as a spontaneous, high-energy party, with shirts twirled like rally towels and chants echoing throughout the stadiums.
Conflicting Reports & Gaps
Sources differ on the precise origin: a few attribute the first MLB instance to the Stephen F. Austin club baseball team, while others trace the gesture to the 2025 Oklahoma State football fan. No definitive timeline reconciles these accounts.
