Los Angeles Dodgers reliever Blake Treinen paid tribute to conservative activist Charlie Kirk during Friday night’s game against the San Francisco Giants by wearing a cap featuring Kirk’s name alongside a cross. The gesture occurred as Treinen entered the ninth inning, drawing attention from fans who noticed the message on his headwear.

Kirk, 31, was fatally shot Wednesday during a campus event at Utah Valley University. He was struck by a single bullet and later declared dead. Tyler Robinson, a 22-year-old Utah resident, was arrested as a suspect in the killing. Utah Gov. Spencer Cox disclosed that a family member of Robinson contacted authorities with claims the suspect had confessed to the incident.

Other sports teams also honored Kirk following his death. The Green Bay Packers observed a moment of silence for him before their game against the Washington Commanders on Thursday night. Kirk, founder of Turning Point USA, was a prominent ally of former President Donald Trump, who condemned his assassination on social media and announced plans to posthumously award Kirk the Presidential Medal of Freedom.
