Mets' Marcus Stroman Calls Out 'Racist Undertones' After Bob Brenly's Do-rag Remark

New York Mets pitcher Marcus Stroman was unhappy with comments made by Arizona Diamondbacks broadcaster Bob Brenly during Tuesday's game. 

Brenly attempted to make a joke about a do-rag Stroman wore under his hat, suggesting it was the same one "Tom Seaver used to wear when he pitched for the Mets."

Stroman tweeted after the game that the comments contained "racist undertones."

Brenly, who is white, has been the color commentator for Diamondbacks games since the 2013 season. 

Stroman also retweeted the Washington Post's Chelsea Janes, who called Brenly's comments "racist and unacceptable" and that the Mets pitcher "deserves an apology."

Mets manager Luis Rojas also took exception to Brenly's comments, per Deesha Thosar of New York Daily News:

Per Saleam Singleton of Byrdie.com, the do-rag became "a necessary tool for Black men, used to train their curl patterns or to lock down hairstyles during sleep" in the 1970s. 

Singleton added in the 1990s that do-rags "started to become a symbol of inner-city Black culture."

Stroman, who has dreadlocks, uses a do-rag to keep his hair in place under his hat. The right-hander tossed six innings against the Diamondbacks on Tuesday.
