In the first round of Wimbledon, Zheng Qinwen faced Lulu Sun, a qualifier ranked outside the top 100, who had never won a Grand Slam match before. Despite winning the first set 6-4, Zheng lost the next two sets 2-6 and 4-6, double-faulting in a crucial service game. This handed Sun her first Grand Slam victory and first win against a top-ten player.
