"Update: The Athletic’s Brittany Ghiroli confirmed AA’s reporting that Brown was taken off the air over his comments ahead of that final Rays’ game, and added that he was only on radio on the Phillies’ series thanks to another issue. “Multiple sources briefed on the decision say ownership has enacted a new policy mandating that their broadcasters wear only team gear when on-air, which has rankled some. That snafu lead to Brown filling in on radio after his comment in the Rays series because another broadcaster got in trouble. Broadcasters have also been reprimanded previously for mentioning past Orioles players who are no longer with the team.”
