Los Angeles Dodgers relief pitcher Blake Treinen says Major League Baseball contacted him last season after he wore a cap displaying the name of conservative activist Charlie Kirk. Treinen described being “chastised” by MLB in connection with the hat message. The reports say the incident occurred during a game after Kirk was killed, when Treinen wrote Kirk’s name on his cap as a tribute. Multiple outlets frame Treinen’s account as an MLB warning or reprimand, without detailing any further disciplinary outcome in the cited coverage. The stories rely on Treinen’s statements and do not provide additional specifics about what MLB said beyond characterizing it as a reprimand. Overall, the coverage centers on Treinen’s claim that MLB challenged his use of Kirk’s name on the uniform following the activist’s death, and it highlights the league’s involvement in responding to the on-field display.
