Blake Treinen Reprimanded by MLB Over Cap Message and Placed on Injured List

Blake Treinen MLB uniform policy elbow injury Los Angeles Dodgers Charlie Kirk

Los Angeles Dodgers reliever Blake Treinen said Major League Baseball warned him after he displayed the name of conservative activist Charlie Kirk on his cap during a September 2025 game. Treinen explained the league told him that personal messages on uniforms violate MLB policy and, while no discipline was imposed, future infractions could carry penalties. He linked the warning to similar actions taken against San Francisco Giants relievers for Bible verses on their hats.

On June 20, 2026, the Dodgers moved Treinen to the 15‑day injured list because of right‑elbow inflammation. He had earned the win in a walk‑off victory the day before, but the exact cause of the injury was not immediately disclosed. The team recalled right‑hander Chayce McDermott as a replacement.
