The incident involving San Francisco Giants players writing on their Pride Night caps led Major League Baseball (MLB) to issue a warning regarding uniform policy violations. The league stressed its regulations, emphasizing that players should refrain from displaying any personal messages or nicknames on their attire.

San Francisco starter Landen Roupp marked his cap with the Bible verse “Gen 9:12-16,” alongside the rainbow SF logo during the Pride Night game against the Chicago Cubs. The verse reiterates God’s covenant never to flood the earth again, marked by a rainbow—a symbol of such promise. Roupp explained his action as personal belief and the freedom to express what one believes.

Relievers JT Brubaker and Ryan Walker followed suit with similar inscriptions, leading to MLB’s advisory that future actions might result in policy breaches. While the warning was explicitly non-disciplinary, it reaffirmed uniform regulations prohibiting personalized messages. Past warnings have been issued for benign inscriptions such as family names or holiday greetings.

“To be clear, this routine verbal warning not to wear the hat in future games is not disciplinary and had absolutely nothing to do with the content of the message.”

MLB has been proactive among major U.S. sports leagues in organizing Pride Nights, coordinating events with community leaders and entertainers, and incorporating tailored patches and logos during Pride Month. Giants manager Tony Vitello noted that players exercised freedom in choosing personal expressions without prior discussion.
