Cori “Coco” Gauff (born March 13, 2004) is an American tennis player. She is a former world No. 1 junior, having won one junior Grand Slam singles title and another in doubles. She was the runner-up in the girls’ singles event at the 2017 US Open, making her the youngest finalist at the event in the tournament’s history.
Born to athletic parents with NCAA Division I collegiate backgrounds in basketball and track and field, Gauff experimented with a variety of sports as a child. She chose to focus on tennis, having been inspired to play by the Williams sisters and because of her preference to compete in an individual sport. Gauff had quick success as a junior, winning the Little Mo eight-and-under nationals and earning a sponsorship to train at Patrick Mouratoglou’s academy in France. She began playing on the ITF Junior Circuit at 13 and reached the final at the junior US Open in just her fourth ITF event. She won two junior Grand Slam tournament titles, one in singles at the 2018 French Open and one in doubles at the 2018 US Open.
Gauff made her WTA Tour debut in March 2019 at the Miami Open and won her opening match. She received a wild card into the qualifying draw at Wimbledon where she became the youngest player to qualify for the main draw in the tournament’s history. She then rose to prominence by defeating Venus Williams in the first round, and ultimately reached the fourth round of the event. Each of her matches was the most-watched of the day in the United States.
