Clint Frazier is standing up for himself.

The outfielder for the New York Yankees expressed his discontent with a broadcaster’s comment earlier this week.

Michael Kay of the YES Network is the play-by-play announcer for Yankees baseball broadcasts, and on Monday’s episode of his self-titled TV show, he seemingly criticized Frazier for his health woes this season. After commenting on Frazier’s “inability to get healthy,” Kay faced immediate backlash, considering concussion concerns are what have limited Frazier to only 15 games so far this year.

The 23-year-old MLB star responded to Kay’s tweet that he was just being “facetious.” Frazier expressed that he did not appreciate the commentary and that he was trying his best to get back to good health and back on the field. His tweet read: “@RealMichaelKay facetious or not, I don’t appreciate what you said today. I’m doing everything I can to get healthy so I can play symptom free … so steer clear of publicly calling me out for not when we haven’t even had one convo about my concussion this year. #ShameOnYouBro”

Frazier has been sidelined since mid-July due to recurring concession signs and symptoms. Along with injuries to Jacoby Ellsbury, Aaron Judge and others, the second-place Yankees have been left scrambling for depth in the outfield as the chase another World Series title.

Earlier this year, Frazier had to combat inaccurate reports that he had requested to wear the retired No. 7 jersey that belonged to Hall of Famer Mickey Mantle. The report was debunked and an apology was issued.
