Zheng Qinwen 郑钦文 became the first Chinese woman to win Olympic gold in tennis singles. As surprising as this tournament victory was, the 21-year-old earned it. Zheng put an end to Angelique Kerber’s career in the quarter-finals. In the semi-finals, she knocked out the top favorite Iga Świątek before the crowning glory followed in the final: 6:2 and 6:3 against Croatia’s Donna Vekić. All of this came as a surprise. Zheng has only won three small tournaments so far.
