Bob Brenly has apologized for a comment he made about Marcus Stroman's head covering during Tuesday night's game.

Brenly, who now calls Arizona Diamondbacks games for Bally Sports Arizona, made a crack about Stroman's attire during the fourth inning Tuesday.

"Pretty sure that's the same do-rag that Tom Seaver used to wear when he pitched for the [New York] Mets," Brenly said during the telecast.

Stroman had tweeted that the comment had "racist undertones."

Brenly issued a statement on social media before Wednesday's Mets-Diamondbacks day game.

"During last night's game, I made a poor attempt at humor that was insensitive and wrong," the statement said. "I apologize to Marcus Stroman and have reached out directly to share those thoughts. I have had several conversations with the D-backs and we agree that seeking sensitivity training is an important step so I can continue to learn from my mistakes in order to be better in the future."
