A bit of a controversy emerged at the U.S. Open on Wednesday following a second round match between world No. 26 Jelena Ostapenko and Taylor Townsend, in which Townsend pulled off a straight set upset before the two had a tense post-match exchange at the net.
Ostapenko later accused Townsend of breaching one of the unwritten rules of tennis etiquette, where players are supposedly meant to apologize if a winning ball clips the net.
