Mets star Marcus Stroman is NOT happy that a quip was made about his du-rag during a TV broadcast Tuesday ... with the pitcher saying the comment had "racist undertones" to it.
The remark went down during the 4th inning of the Diamondbacks' broadcast of the Mets-DBacks game ... when color commentator (and former World Series-winning manager) Bob Brenly threw a jab over Stroman's visible head covering.
"Pretty sure that's the same du-rag that Tom Seaver used to wear when he pitched for the Mets," Brenly said.
The comment was met by immediate backlash on social media .
