Taylor Townsend and Jelena Ostapenko were involved in a heated exchange at the end of their second-round match on Wednesday

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.
