Following Serena William's claim of sexist behaviour by umpire Carlos Ramos at the 2018 U.S. Open women's final, the Herald Sun's cartoonist Mark Knight drew an illustration of the match which was described as sexist and racist. In the cartoon, Williams is shown to have smashed her racket whilst a baby's dummy lays on the floor. Knight's illustration has been compared by some, including the political cartoonist and Washington Post columnist Michael Cavna, to illustrations popular during the Jim Crow era in the United States.[13] Knight is also accused of making Williams' Japanese opponent, Naomi Osaka, appear as a "white woman".
