Ostapenko unleashed a verbal volley at her American opponent for being disrespectful during their second-round match.

Taylor Townsend says Jelena Ostapenko told her she has "no class" and "no education" after the American beat her in the US Open second round.

“She told me I have no class," Townsend said in an on-court interview after her 7-5, 6-1 victory.
