Naomi Osaka said using words like “no education” and “no class” to criticise a Black tennis player were among the worst things to say as the debate over a heated row between Taylor Townsend and Jelena Ostapenko raged on at the US Open.

Townsend, who is Black, overcame 2017 French Open champion Ostapenko 7-5, 6-1 in a tough second-round battle on Wednesday.
