Top prosecutors in multiple states have launched investigations into Major League Baseball after the league issued warnings to San Francisco Giants players for displaying Bible verses on their hats during a recent Pride Night game.

The controversy began last week when Giants pitchers Landen Roupp, JT Brubaker, and Ryan Walker wrote “Gen 9:12-16” on their rainbow-themed caps. The scripture cited the biblical covenant with Noah, which references the rainbow as a divine sign. Following the game against the Chicago Cubs, Major League Baseball notified the players that their actions violated uniform policies. An MLB spokesperson later stated that the warning was “not disciplinary” and unrelated to the content of the message, emphasizing that league rules prohibit any personal messages on equipment or apparel. The league also noted that similar warnings have been issued for other personal inscriptions, such as “Dad” or “Happy Mother’s Day.”

Despite this explanation, the issue has attracted significant attention from state and federal officials who contend the league’s enforcement may be selectively targeting religious expression. On Saturday, Florida Attorney General James Uthmeier confirmed that his office had issued an investigative subpoena to MLB. The inquiry aims to determine whether the league’s uniform regulations discriminate against Christian players. The subpoena demands production of documents related to uniform rules, enforcement history, and internal communications by July 23. Florida, home to two MLB teams, is scrutinizing the league under the Florida Civil Rights Act and the Florida Deceptive and Unfair Trade Practices Act.

Missouri Attorney General Catherine Hanaway, representing another state with two MLB franchises, has also threatened an investigation. Hanaway called on MLB to pledge that players would not be disciplined for refusing to wear Pride Night uniforms or for writing Bible verses on their hats. She argued that baseball, as the nation’s pastime, should not discriminate against players based on their moral, political, or religious beliefs.

The federal Department of Justice (DOJ) has similarly stepped into the matter. DOJ Assistant Attorney General Harmeet Dhillon announced that the DOJ referred the issue to the Equal Employment Opportunity Commission for further investigation. Dhillon criticized MLB for permitting other forms of expression, such as players wearing “Black Lives Matter” patches, while allegedly punishing those voicing religious objections. “They don’t mind when players are taking a knee and exhibiting all kinds of stuff on the job, but when people are pushing back on being forced to promote a sexual practice that is against their religion, they’re threatening them,” Dhillon said.

MLB has maintained that its uniform policy is neutral and consistently applied, emphasizing that the warnings relate to any unsanctioned messages regardless of content. The league has not formally disciplined any players over the issue.

As the investigations unfold, MLB faces mounting pressure to clarify how it balances uniform standards with players’ rights to religious expression amid an increasingly charged cultural environment. Representatives for the league have been contacted for comment.
